BOSTON — Robots in Northeastern College’s new EXP constructing wield chopsticks, rotate platforms and appear to be snakes. Roboticists on the Institute for Experiential Robotics’ lab mentioned they’re conducting transformative analysis.
The robots are dealing with chopsticks for exact manipulation. Analysis continues with a snake-like robotic created for NASA’s BIG Concept Problem that may navigate in sandy environments just like the moon. And the lab has fabrication rooms for electronics, 3D printing, and laser slicing.
The brand new area takes up the vast majority of the primary degree of the eight-story science and engineering complicated on the college‘s Boston campus. Its excessive bay space is in regards to the dimension of a basketball court docket. It’s decked out with robotics methods spanning the technological gamut, together with collaborative robots, industrial robotic arms, cell robots, drones, digital actuality methods, and rather more.
The institute additionally has area on the seventh ground of EXP that features extra robots, in addition to desk and laboratory area for researchers to conduct their work.
Northeastern lab focuses on human-robot interplay
“Our mission is easy in my thoughts — enrich human experiences by significant improvement and deployment of robotics know-how,” mentioned Taskin Padir, a Northeastern robotics professor and the director of the institute.
“We’ve been working with the design group for the previous six years even earlier than the groundbreaking of the constructing,” he mentioned. “We had a imaginative and prescient for the area the place we are able to reveal what we imply by ‘experiential robotics.’”
A number of Northeastern college students and college members within the lab are engaged on tasks being led by Padir.
VERA might change how workcells look
As a part of a Nationwide Science Basis grant, Northeastern developed a collection of robotics functions designed to assist employees within the seafood packaging business use robots to maneuver and pack merchandise.
A type of methods concerned making a workstation that options an assistive robotic desk. The title of the robotic system is VERA, which stands for “voxel-enabled robotic assistant.”
Embedded within the desk is a collection of robotic cube-like gadgets referred to as voxels. The voxels are in a position to spin to maneuver of an object, equivalent to plastic packaging. The workcell additionally encompasses a mounted digicam to trace the motion of an object.
“The thought right here was motivated by us having gone to seafood manufacturing websites and seeing folks lower up actually massive fish like tuna and noticing that that they had plenty of bother transferring round sure elements,” defined Mark Zolotas, a analysis scientist at Northeastern. “In order that motivated us to design a robotic that wouldn’t intrude along with your workspace.”
It’s just a little totally different than what one would anticipate a typical automated workcell to look, since there aren’t any robotic arms concerned, he famous.
“We type of see it as being a basic means of rethinking about the best way we view robots on the whole,” mentioned Zolotas.

Institute for Experiential Robotics conducts interdisciplinary analysis
As of now, 20 college members working in a lot of disciplines together with robotics, synthetic intelligence, laptop science, bodily remedy and entrepreneurship have a presence within the new area, Padir mentioned.
“It’s not the area or gear that creates information or pushes the boundaries of analysis,” he added. “It’s the folks. With out researchers, we can not do something. It really works in a hierarchical means — we’ve got college who set the imaginative and prescient for tasks then we’ve got full-time postdoctoral researchers who assist information the Ph.D. college students. We even have a really massive cohort of grasp’s college students in robotics. I envision they may become involved.”
“The institute additionally all the time gives experiential studying alternatives for our undergraduates. We now have a monitor report of recruiting certified college students in our institute, so they may become involved in our analysis,” Padir mentioned.
Hanumant Singh, a professor of robotics at Northeastern, has a lot of robots housed within the lab, together with robots designed for underwater use. He says one of many key improvements of the lab is that it lets robotics researchers work collectively in a shared area.
“The largest and an important a part of that is that we’re working as a collaborative,” mentioned Singh, who notes the lab’s massive open area permits for modularity and permits researchers to make use of it any means they see match. “It’s an open area that doesn’t belong to anyone that’s reconfigurable primarily based on the mission and the folks which can be engaged on stuff.”
Julie Marble, govt director of the institute, echoed Singh’s sentiment.
“One of many foremost objectives for the Institute for Experiential Robotics is to turn into the flagship for robotics at Northeastern,” she mentioned. “If you wish to have robotics at that degree, it’s good to be not solely interdisciplinary however you additionally have to have plenty of collaboration. One of many objectives of this area is to create an area the place all of our college and their grad college students can work collectively collaboratively.”
COBRA copies biology to roll onward
Doctoral college students Adarsh Salagame and Kruthika Gangaraju are definitely benefiting from the area. They had been a part of the group behind the COBRA system, or the Crater Observing Bio-inspired Rolling Articulator.
Northeastern snake-like robotic was created for NASA’s BIG Concept Problem, which referred to as on groups of scholars to develop a robotic system designed to navigate troublesome terrain. Alierez Ramezani, a Northeastern assistant professor {of electrical} and laptop engineering, led the group that developed the mission.
The researchers’ objective was to develop a robotic that would function on the lunar south pole. They turned to nature to discover a answer, mentioned Salagame throughout an illustration.
“Snakes are well-documented to have the ability to function in these sandy environments,” he mentioned. “Different typical robots don’t function in these sorts of environments, in order that’s the place the snake locomotion happened.”
One notable side of the COBRA system is its skill to attach each of its ends to create an ideal circle, which permits it to simply roll down hills whereas utilizing little vitality, defined Marble.
“It may journey an especially lengthy distance with out shedding any energy,” she mentioned.

HASHI takes a chopstick strategy to manipulation
Austin Allison is one other one among Padir’s college students. A doctoral scholar finding out bioengineering, he’s a part of the analysis group that created HASHI, or the Extremely Adaptable Seafood Dealing with Instrument for packaging.
Allison confirmed the robotic system in motion, which features a robotic arm and end-of-arm instruments that appear to be chopsticks. (Hashi can also be the Japanese phrase for chopsticks.)
The robotic is designed to deal with and transfer small items of fish meals like sushi, he mentioned. And what’s one of the best ways to deal with sushi? With chopsticks, after all.
“We thought, ‘Effectively, there’s most likely been 1000’s of civilizations and billions of individuals all through historical past which have used chopsticks not just for sushi however [also] to prepare dinner total meals,’” Allison recalled.
He famous that every chopstick appendage has three levels of freedom and might be managed utilizing a online game controller. The robotic chopsticks are in a position to manipulate the gadgets in hand pretty simply. Ideally, this method might be used for packaging of pre-made meals, equivalent to Lunchables.
“There’s a time period in robotics referred to as ‘hand manipulation,’ which is if you wish to consider choosing one thing up and doing it like a pinch and roll,” mentioned Allison. “It’s attention-grabbing to have the ability to do it on a small scale.”

Northeastern dedicates area at EXP for robotics
Allison mentioned that the brand new robotics lab has been a fantastic addition and that he loves that he now has extra space to do devoted analysis.
“Our desks are a bit extra separated from loud and distracting equipment, in addition to bigger {hardware} that’s saved on the primary ground,” Allison mentioned. “We even have extra devoted rooms for fabrication, like a purpose-build machine store, an electronics/3D printing/laser slicing room, and many others.”
As he progresses by his doctorate, Allison mentioned he’s excited to take a look at extra of what’s on supply in EXP.
“Having future entry to among the beforehand unavailable tooling within the first ground of EXP — waterjet cutter, CNC router and mill, welding, and many others. — will allow me to effectively prototype and create extra superior {hardware} for future robotics tasks and endeavors,” added Allison.
