The prototype of the STARFISH underwater gripper developed by RE2. | Supply: Sarcos
RE2 Robotics, a completely owned subsidiary of Sarcos Expertise and Robotics Company, introduced that it reached a technical milestone on its Robust Tactile mARitime hand for Feeling, Inspecting, Sensing and Dealing with (STARFISH). The corporate has efficiently assembled and lab examined a whole gripper that may grasp and maintain quite a lot of objects.
STARFISH is an underwater end-of-arm tooling that’s outfitted with tactile suggestions. The gripper will likely be deployed with the U.S. Navy for mine countermeasures and explosive ordnance dispose (EOD). The challenge is being funding by means of the U.S. Navy’s Workplace of Naval Analysis (ONR).
“The way in which they deal with EOD’s now could be they sometimes ship a diver down within the water to render a menace protected. You’ll be able to take into consideration the united statesCole, for instance,” Jorgen Pedersen, Sarcos COO and former RE2 CEO, mentioned. “That will be an instance the place if that they had suspected that there could be a menace there, they might ship a diver right down to go attempt to care for that. Now now we have the flexibility to copy that diver functionality in robotic type.”
The STARFISH prototype makes use of three tactile-sensing fingers to grip small and bigger objects. It’s even capable of carry out wonderful motor abilities like squeezing tweezers. The grippers fingers conform to the form of the objects its holding, which permits it to deal with objects on contact.
The prototype is sturdy sufficient to face up to turbulent underwater circumstances, like ocean swells and different hazards. Its fingers are coated in a multimodal tactile sensor pores and skin that enables them to really feel regular and shear forces.
Sarcos developed this expertise with Dr. Veronica Santos, the director of the Biomechatronics Laboratory at UCLA, and Dr. Jonathan Posner, a professor of mechanical engineering and chemical engineering on the College of Washington.
“[The skin] offers completely different types of suggestions—stress, temperature, vibration—in order that the identical kind of sensing that you’ve got as a human you’re getting now on the finish of the robotic’s fingertip,” Pedersen mentioned.
The gripper will be teleoperated and might carry out some autonomous capabilities with a human at all times within the loop to ensure issues are working easily.

Within the subsequent part of the challenge, the STARFISH gripper will likely be hooked up to Sapien Sea Class underwater arms mounted onto an underwater remotely operated car (ROV). Whereas the expertise is being developed to be used within the Navy, in keeping with Pedersen the corporate hopes to use it to extra functions sooner or later.
“What’s cool about this expertise is it’s foundational,” Pedersen mentioned. “This identical expertise that works underwater can work on land. So, it’s not restricted to subsea, we simply occurred to choose the toughest surroundings to work in. So my confidence in extending this right into a terrestrial utility may be very excessive.”
RE2 was acquired by Sarcos in March 2022 for $100 million. The deal consists of $30 million in money and $70 million of Sarcos frequent inventory, and is anticipated to shut within the second quarter of 2022.
“It was an ideal strategic match type each side. Each firms had basically the identical mission,” Pedersen mentioned. “We’re enhancing employee security and productiveness by means of robotics. So there was no change within the aim by bringing these two firms collectively.”
The deal practically doubles Sarcos’ engineering crew and provides Pittsburgh, one of many world’s main robotics clusters, as a second location. RE2 will finally be rolled up into the Sarcos model however will stay in Pittsburgh.
