A SeaJelly Robotics BootCamp with Boston Students

During the Boston Public School’s (BPS) Winter Vacation, February 20 – 22, GreenSight was host to a Robotics Bootcamp at our Boston facility; nine (9) BPS students participated. Guided by seven members of our staff, the students took a deep dive into aquatic robotic technologies as they worked together to build their first SeaJelly.

While the students learned how to mold silicon rubber components, solder electronic circuits, and program real time processors, the GreenSight staff participants learned better ways to communicate concepts and teach skills. However, the most important thing we learned is that building a SeaJelly really is fun; the students’ enthusiasm was high, and they enjoyed all three days. (So did we!)

Key to Moving Our Project Forward

The overall project vision is to create an ecosystem of STEM education tools and resources based upon soft aquatic robots that attracts the attention of and educates students K-12 and beyond. SeaJelly is the project’s first robot design. We know that it is fully capable of underwater operations, yet simple to build.

Our next step is to learn the best ways to teach students the necessary foundational concepts and then find the most effective ways to guide them through the process of building a functional SeaJelly. The bootcamp was key to this step, bringing in a group of students new to robotics and finding out what works and what doesn’t for the teaching and guiding.

 Building a SeaJelly

The intense, three-day bootcamp was focused on creating, assembling, and integrating all the SeaJelly components. The students first learned how to build molds for the SeaJelly body, then prepare and pour the silicon rubber that filled those molds. Electronic assembly was next, building the controller and soldering the connections. Lastly, writing the real-time software that directs SeaJelly’s underwater operations.

This process, building a SeaJelly from scratch, gave the students a truly unique learning experience. They worked, hands-on, with a range of technologies to make the individual components, then learned about system behaviors as they pulled them together into a functioning unit. This approach to STEM education is challenging for instructors but in the bootcamp we saw, firsthand, the rewards of deeply engaged students learning new things, trying their own ideas, and absorbing an ‘I can make this work’ attitude.

Partnering with the Boston Community

It’s important to recognize our partners in the Boston community who assisted in making the bootcamp possible.The Boston Private Industry Council (PIC) is a nonprofit organization at the intersection of education and workforce development. Among its tasks is connecting Boston students to promising career pathways; robotics certainly fits that description. Our event was organized under the auspices of PIC’s industry bootcamp program, which includes payment as interns for the students.

Boston Public Schools (BPS) was key, coordinating the participation of students from three different city high schools.

Jim Sproul, part of our project team and a bootcamp STEM instructor, used his experiences from bringing MIT robotics courseware, BeaverWorks, into BPS schools. He is also on the BPS STEM committee.

A Great Student Response

Our bootcamp was held during a school vacation week. The students, a self-selected group interested in technology, were enthusiastic and thoroughly engaged from the beginning.  All of them are members of underserved communities; sadly, some do not have access to a computer at home. Most were bilingual, with languages, in addition to English, including Somali, Spanish, and Vietnamese. Getting a stipend from PIC certainly helped but they chose working with SeaJelly over hanging out with their friends.

Debugging software, one of bootcamp’s biggest challenges

The background material we taught was not trivial and the students were asked to perform totally new tasks, yet their positive attitudes never wavered. The post-program survey showed they were never totally comfortable with what we asked them to do, indicating how they were pushed by the challenges. But the survey also showed overwhelming interest in further work with SeaJelly as an after-school STEM program, demonstrating that the hands-on approach to learning about technology is highly effective.

The GreenSight Staff Learned A Lot

While the students were learning about SeaJelly-related technologies, the GreenSight staff was learning even more about how to teach and guide. As the students moved through the bootcamp activities they ran into roadblocks, concepts they did not fully grasp and techniques that were difficult to implement.

We also learned about individual differences. “There are different levels of aptitude for precise physical tasks, like building a mold,” commented Maria Kloiber, a mechanical engineer and one of our project leads. “I knew that intellectually but actually helping different people really puts it into perspective. Anyone can learn how to build a mold, but for some folks it takes a little longer.”

 Summary

The SeaJelly bootcamp was a great success on two levels. In the short term, it was a rich learning opportunity for our nine students. They learned multiple concepts related to robotics and biomimetics, grasping them in a way unique to the hands-on approach. They also learned how to lean into and absorb totally new technologies, an ability critical to success in the future world where they will work.

In the longer term, GreenSight gained important insights into requirements for the lesson plans and other educational materials we are developing. Our materials can now anticipate and address the roadblocks the bootcamp students encountered. This is very important as we move forward towards one of our Phase II goals, organizing a SeaJelly-based STEM after-school program at multiple BPS high schools, culminating with a competition.

Autonomous Vehicles as a ‘Family Affair’

Autonomous Vehicles as a ‘Family Affair’

Adrita and Soham Samanta bring RACECAR to Tufts University

Autonomous vehicle technology will drastically change our world, but when? Full of promise but fraught with controversy, perhaps it really belongs to the next generation. If that is true, a teenage sister and brother team in Boston is ready to take ownership.

Adrita Samanta and her younger sibling Soham got started a couple of years ago, assembling a small robotic vehicle, called RACECAR*, as part of MIT’s Beaver Works Summer Institute (BWSI). Building on that effort, and expanding their skills, Adrita and Soham developed their own operational software for RACECAR’s onboard computer. The software takes input from advanced sensors, then, in response to human direction, makes decisions that drive electronic commands controlling the car.

The pair advanced their autonomous vehicle expertise to the point where they have served as guest lecturers – at the college level.

Presenting at Tufts

In October, the Samantas brought their RACECAR to a Tufts University classroom, presenting and demonstrating during a session of ‘The Impact of Self-Driving Cars’. This interdisciplinary course examines the technologies, human-factors, key players, and far-reaching implications of autonomous vehicles.

Adrita’s presentation introduced the self-driving technologies in RACECAR, then got into some of the design details. This was followed by demonstrations, with Tufts students participating, of the RACECAR following a small orange pylon around the classroom.

Competence Not Always a Function of Age

“It was amazing to see how Adrita captured the complete attention of the Tufts students,” said Jim Sproul, a Tufts Guest Speaker who facilitated the Samantas’ participation in the class. “They quickly recognized that she was truly an expert in this facet of autonomous technology and were quite willing to learn from her, even though she was a lot younger. “

“RACECAR was the experience that first got me interested in robotics,” explained Adrita.” After that I began working in a Tufts University lab under the supervision of Prof. Jivko Sinapov. Now I am taking Math and Computer Science courses at Tufts while working on a Cloud Computing project in Prof. Raja Sambasivan’s Tufts lab as an MIT PRIMES student.”

Preparing Students for Tomorrow’s World

 

Tufts students explore ‘The Impact of Self-Driving Cars’

“Our course ‘The Impact of Self-Driving Cars’ helps students understand this rapidly emerging technology and appreciate the powerful ways it will impact the future of their world,” said Hal Miller-Jacobs,  one of the course instructors at Tufts. “It was so meaningful for our students to see young people interested in moving technology forward. We often only hear the ‘bad’ news about kids, so this experience was refreshing and encouraging for our future.”

Dr. James Intriligator, the other instructor, was equally enthusiastic. “It was great that Jim Sproul could bring the Samantas to visit our class as guest lecturers. The students were incredibly impressed with Adrita and Soham – their knowledge and passion were inspiring. At the end of the semester many listed the RACECAR visit as one of the class highlights. Beyond just RACECAR, our students were also extremely interested in the innovative STEM classes that Jim has enabled for greater Boston public schools.”

Some Background on RACECAR

RACECAR itself deserves some attention. There are two versions, (1) MIT RACECAR Model Nano and (2) RACECAR-Zero.

Model Nano is the high-powered version used by the Samanta’s. The kit of components, costing around $750, includes LIDAR and IR sensors, a battery, an NVIDIA GPU computer, and a chassis with flexible front-end steering. It is a sophisticated package capable of advanced self-driving functions, used during BWSI by selected high school students who first assemble, then program the robotic cars.

A lower kit cost was required to make the BWSI approach broadly available to middle and high school STEM programs. That was achieved with RACECAR-Zero, a kit that includes a Pi video camera, a Raspberry Pi Zero computer, disposable batteries, and a differential-steered chassis. With a total cost of around $125, RACECAR-Zero can be programmed to autonomously navigate a track with a variety of curves. “A shout out to Bob Cassels, an avid volunteer to the Beaver Works program and supporter of STEM education who made RACECAR-Zero a reality,” said Sproul.

STEM Education Really Can Be Exciting

“RACECAR has been a wonderful hands-on STEM education opportunity for Soham and me,” said Adrita. “Making design choices, discovering how components interact, and debugging problems, these are all great ways to learn. Then there is the reward of watching the car do what we wanted it to do.”

So yes, a couple of things are true. Autonomous vehicle technology really does work and STEM education really can be exciting. “I have been involved with RACECAR for over four years, and it always gets an enthusiastic response, ”shared Sproul. “It’s just a great may to teach STEM skills to middle school and high school students, helping them work together in small groups to create their own solutions to design challenges.”

Meeting SeaJelly

On Saturday, October 21, 2023, students in Boston Public Schools (BPS) had an opportunity to interact with a soft body, aquatic robot called SeaJelly. The annual BPS STEM Fair introduces kids from Boston communities to new, innovative technologies, a category where SeaJelly clearly qualifies.

The word ‘robot’ makes us think of intelligent devices that roll or walk, using jointed mechanical ‘arms’ to accomplish various tasks. SeaJelly is intelligent but it is constructed using flexible and deformable, not rigid, materials. Like a jellyfish, it uses flexible tenacles to swim and do its underwater work. While SeaJelly is a first-generation device, the future applications for soft body, aquatic robots range from marine pipeline repair to managing undersea farms.

Created using simple, low-cost components, SeaJelly represents a collaboration between Greensight, Inc., Florida Atlantic University (FAU), and The Sproul Company (TSC). “SeaJelly’s design uses biomimicry to create a free-swimming soft robot that is well-suited to operating in an underwater environment, “said Joel Pedlikin, COO of GreenSight. “The biomimicry also seems to have resulted in something people find very engaging.”

That may be an understatement – the kids at the STEM Fair loved SeaJelly. Takin Tadayon, an engineer with GreenSight, was one of the demonstrators at the Fair and got to see the kids’ excitement firsthand. “The students were great, with lots of awesome questions,” he said. “They really liked the way it actually looked like a sea animal and were just totally open to learn about SeaJelly.”

SeaJelly is being developed as part of a project funded by the Office of Naval Research. The goal is to teach K-12 students the principles of biomimicry and soft robotics, ultimately providing kitted soft robots that students can build, modify, and improve upon. Judging by the STEM Fair reactions, the project is off to a good start.

“I want to thank GreenSight and BPS for making SeaJelly accessible to Boston students, “said James Sproul, founder of TSC. “It was a hands-on learning experience with an exciting technology still in its infancy. As STEM educators, our mission is to prepare kids for tomorrow’s opportunities; this was a good step in that direction. We look forward to partnering with the GreenSight team in curriculum development, classroom enrichment, and BPS STEM competitions.”

Northeastern University Intern Shares a Unique STEM Mentorship at Madison Park

 

A new STEM class is being piloted at Madison Park Technical High School. Cardinal Works, which is adapted from theMIT LL Beaver Works RACECAR curriculum, is currently being taught to a small group of juniors at the school. Theclass meets every other week for about two hours per day, led by Mr. Berger. It will culminate in the students racing autonomous cars that they have designed and programmed themselves, and I am excited to be a part of the effort.

 

A Little About Me

My name is Ishika Choudhary, and I am a fourth-year student at Northeastern University studying Computer Scienceand Mathematics. This is my final semester, and I am happy to be an intern for the Cardinal Works program while Ifinish up my classes. I’ve been a teaching assistant for computer science classes at Northeastern for about two years but working at Madison Park has provided me with a new experience.

Teaching Our Class Python

So far, the students have learned the basics of Python. This will be necessary for when theybegin programming the cars. Working on Python with a younger age group has been a fun challenge for me after working with college students. I’ve had to explain concepts in a simpler way, which in turn has made me gain a deeper understanding. You need to understand a subject well in order to make it easier and teach it! It’s also been rewarding to help the students; I love to see them grasp the concept and apply it themselves. Additionally, since the class is small it’s easy to walk around to help the students and feel like I’ve helped them accomplish something by the end of the day.

Our Cardinal Works Students Learn to Design & Cut Their Robotic Vehicles

As much as I love Python, I think my (and the students’) favorite part so far has been designing the chassis of the car. This has been our latest lesson, and the students have learned to use Cuttle.xyz to design the sides and bottom of their cars. In the following weeks, we will laser cut the designs and assemble the cars! From sports cars to the Spongebob Patty Mobile, they have been very creative with this task. I think it is making them more interested in the program as they are building out something that they like. This part of the process has also been completely new for me. As a computer science major, I rarely see the engineering side of things, but it’s been a great experience for meas well learning the Cuttle software. I’m excited to build the cars in the following weeks and get some experience with that as well!

I recommend this program to any college students who have some extra time and are looking to teach. It does require some patience, but I personally love seeing the outcomes. Also, I’m very excited to work with the cars since I don’thave much experience with robotics and autonomous vehicles. As much as I am helping in the classroom, I’m learning a lot too!

BPS STEM Class Visits Cutting-Edge Robotics Company

BPS STEM Class Visits Cutting-Edge Robotics Company

Seeing a young person’s imagination and ambition come alive is a beautiful thing. It rarely happens for a whole class, but sometimes special things happen.

In mid-January it happened at Boston Dynamics for a great group of 11th grade students from Madison Park Technical Vocational High School (MPTVHS) in Roxbury, MA.

The Students Had Some Hands-on Robotic Experience

The students from Madison Park are taking a unique STEM class called Cardinal Works. Using the RACECAR curriculum, adapted from the MIT – Beaver Works Summer Institute (MIT-BWSI), they are learning all the aspects of first building, then programming a fully autonomous small robotic car. At year’s end, it will drive itself around a complex track.

From the Classroom to an Industry Lab

Jim Sproul is a Cardinal Works instructor at Madison Park and a member of the BPS STEM Advisory Committee. Recognizing the potential student impact of seeing real-world industrial robots, and talking to the people who build them, Jim reached out to Boston Dynamics; the pioneering robotics company agreed to host a visit.

Boston Dynamics has developed dynamically stable, legged machines to the point where their flagship product, a four-legged robot called Spot, is now available for commercial purchase. They have also created, and are still perfecting, an advanced humaniod robot call Atlas. Both Spot and Atlas were part of the Madison Park experience, as the students went into the lab and spoke with robotics engineers.

“Our visit to the Boston Dynamics lab was an extraordinary opportunity for the class,” said Michael Berger, another Cardinal Works teacher. “Seeing Spot and Atlas in action was amazing and allowing the students to ‘walk’ Spot was a truly memorable educational experience.”

Kudos to Boston Dynamics

It wasn’t just the robots that inspired the students, but also the Boston Dynamics field trip host, Cassie Moreira, “ I’m so incredibly happy that we could make this happen, and I truly enjoyed the students at Madison Park. I could tell they were engaged and gave me their full attention.” Cassis said after the visit.

“The kids really resonated with her story,” explained Jim Sproul. “She went to a vocational high school, started with Boston Dynamics as a robotic technician, and is now an electrical engineer. Her enthusiasm for robotics is infectious.”

Everyone at Madison Park is deeply grateful to Boston Dynamics, and especially Cassie, for making the visit so meaningful. “The students raved about the trip,” said Dr. Sidney Brown, Head of School, at MPTVHS . “And when I walked into class the next day, I noticed the 11th graders in Mr. Berger’s class were watching the Boston Dynamics YouTube channel to learn more about robotics”.

Bring RACECAR to Your School

The Madison Park faculty and MIT-BWSI want to help bring the RACECAR Program to more students in Boston and beyond. The need for future-focused technology education is clear and RACECAR has proven itself as an outstanding way to meet that need with hands-on robotic experience.

For more details, reach out to Jim Sproul. He’d enjoy discussing your specific needs and how RACECAR can help your students prepare for tomorrow.
