The Light Duo Mini comfortable grippers are appropriate for meals dealing with. Supply: Ubiros
Dependable and delicate robotic greedy has lengthy been a problem, however Ubiros Inc. mentioned it might clear up the issue with out the cumbersome pneumatics or advanced coding of earlier approaches.
The firm’s electrically pushed and modular grippers are simpler to deploy and use than different comfortable grippers, in keeping with Onder Ondemir, president of Ubiros. He’s additionally a professor within the engineering division at Northeastern College.
Ubiros affords the Light Flex Module and Light Flex CC for customers that need to construct their very own grippers. The spinout of Worcester Polytechnic Institute (WPI) additionally affords Light Duo with two comfortable fingers and Light Professional with 4 fingers, in addition to Contact fashions for each that embrace power management, half sensing/affirmation, and a low-power mode.
The Natick, Mass.-based firm mentioned its compliant grippers are appropriate for meals dealing with and packaging, textiles, and a few warehouse functions. Ubiros, which is a resident startup at MassRobotics, already has distributor agreements in China, South Korea, Turkey, the U.Ok., and the U.S.
Founder fascinated by expertise
“I liked Knight Rider as a child and requested my mother, ‘Who makes [smart car] KITT? What do I have to change into to make one thing like that?’” recalled Ondemir. “She mentioned ‘mechanical engineer.’”
“I grew up and have become an industrial engineer, however I’ve at all times been fascinated with mechanical techniques,” he instructed The Robotic Report. “I labored at an insurance coverage firm modeling the capability of techniques and demand forecasts, and I turned a vp.”
Ondemir later ran right into a buddy [Cagdas Onal] who was doing post-doctoral affiliate work at MIT and collaborating with Harvard College researchers engaged on comfortable robotics.
“We knew the restrictions of pneumatics – precision is low, management is difficult, and the gear wanted to generate compressed air makes use of a variety of electrical energy,” he mentioned. “After spending years within the lab, someday, he got here to me and mentioned, ‘Onder, I believe I’ve groundbreaking expertise for packaging and gripping normally, however I don’t need to run the corporate.’ Turning into the CEO was a no brainer to meet my need to construct machines and work with my buddy.”

The genesis of Ubiros
Ubiros has largely targeted on meals dealing with.
Automating the dealing with of fruit and baked items will not be simple, as a result of such delicate meals gadgets are simply broken, Ondemir famous. Inflexible grippers sometimes don’t have adequate sensitivity, and plenty of different corporations try to resolve issues resembling object detection and singulation, he mentioned.
“In farming, crops are being left to rot within the area, which is a large waste,” added Ondemir. “A key barrier to getting automation is dealing with meals with a comfortable contact.”
“However the actual downside we’re fixing is the employee scarcity,” he mentioned. “Harvesting and packing jobs aren’t fascinating to folks, and there are the problems of effectivity for the employer – most individuals work one shift – and in addition accidents and at last the price of meals.”
Fingers versus suction cups
For many functions the place comparable gadgets are picked, suction cups are adequate, mentioned Ondemir. Nonetheless, when there’s muddle, resembling in e-commerce bins, or tight areas like bookshelves, selecting then requires a mix of sensing to establish every object and the flexibility to singulate that object.
Suction cups are versatile, however porous, dusty, fragile, or oddly weighted gadgets should not at all times appropriate for suction cups, Ondemir noticed.
“We’re proud to be one of many few corporations growing particular person finger actuation moderately than the entire hand,” he mentioned. “For singulation, it might present options in advanced selecting conditions.”
Ubiros Light grippers promise advantages
Ubiros’ Light grippers use electrical servo motors and a cable-driven system much like the tendons of the human hand.
“The issue in designing the system was sustaining softness whereas mechanically working the finger – that’s the place our patent is,” Ondemir mentioned. “Our expertise permits the finger unit to be versatile within the greedy path however very inflexible in twisting or bending sideways.”
Electrical end-of-arm tooling (EOAT) removes the necessity for tubes, valves, and compressors, he mentioned. Additionally, whereas pneumatic techniques have to cycle to aim one other grasp, an electrical one can reposition extra shortly.
As well as, electrical grippers have immediate torque moderately than needing to construct up strain for heavy payloads as hydraulic or pneumatic techniques do, mentioned Ondemir.
As much as 35% of the electrical energy invoice in factories is spent on pressurized air, and 40% of the battery lifetime of a cellular manipulator is consumed by a suction cup, he asserted. Thus, Ubiros’ grippers might save a variety of battery energy for autonomous cellular robots (AMRs) or drones, Ondemir mentioned.
Is Ubiros taking a look at cellular manipulation?
“We’ve had severe conversations with Staubli,” Ondemir replied. “Our gripper could be along with its present arm and base, in contrast to others.”
As well as, United Robotics Group has built-in Ubiros’ gripper with a cellular manipulator that will probably be demonstrated at Automate.
Ondemir surveys tech developments
Past cellular manipulation, Ondemir relied on his expertise in robotics improvement to touch upon present tech developments.
“Synthetic intelligence and machine studying enable us to implement predictive upkeep,” he mentioned. “Our electrical micro-controller is partly a system for power management and partly sensing. It’s in a position to accumulate temperature knowledge from contained in the gripper, plus cycle counts and electrical present to construct fashions to foretell failures. That’s in our roadmap.”
Ubiros will not be presently working with digital twins as a result of it’s tough to know the precise deflection of sentimental objects and the place one thing is in house, acknowledged Ondemir. Loads of analysis is being dedicated to this subject, he mentioned.
What about humanoids? “They’ll must have comfortable elements for security and to protect towards falling,” Ondemir mentioned. “This will probably be a key use for comfortable robotics normally, not simply comfortable grippers. As a result of we’re a by-product of WPI, we have already got comfortable 3D sensors and a patented design of a comfortable arm, however there’s loads nonetheless to do.”
Mechanical intelligence for manipulation
“The thought behind what we name ‘mechanical intelligence’ is that when you can mechanically obtain one thing, you want costly programming, movement management, and imaginative and prescient much less,” mentioned Ondemir. “We constructed one thing that’s under-actuated, with fewer motors to maneuver the joints. Electrical actuation permits us to have full-bodied fingers moderately than hole ones that may be punctured or leak in in any other case sanitary environments.”
“Relying on the form of the item, the gripper can mechanically conform to it. It’s extra forgiving of inaccuracies, and also you don’t want excessive precision,” he continued. “As a result of the grippers bend themselves over an object like an egg or an apple, the power is distributed over a bigger space.”
Ubiros did construct some power management into its Light grippers, permitting customers to extend or lower strain, but it surely’s not needed generally, Ondemir mentioned.
Ubiros and its companions lately participated in a MassRobotics Demo Day. Supply: Ubiros
Ubiros appears forward
The Light gripper is initially tackling labeling and grading of tomatoes and cucumbers, and Ubiros has acquired a variety of curiosity lately from bakeries, mentioned Ondemir. A hygienic gripper might then handle dealing with of uncooked beef, poultry, and fish.
To that finish, Ubiros is in search of funding to make its grippers extra hygienic and sturdy towards cleansing brokers. It’s engaged on safe-food dealing with certifications.
On the commercial aspect, Ubiros is conducting a pilot with Mitsubishi to deal with quite a lot of objects and handle robotic greedy by way of Mitsubishi’s train pendant.
“Down the street a number of years, we need to focus extra on the information aspect, permitting clients to entry knowledge by way of the tip effectors,” Ondemir mentioned. “We plan to finally deliver different patented applied sciences into the office – 3D sensors, haptic gloves, human-in-the-loop techniques, distant manipulation, and comfortable arms.”
Ubiros will probably be on the Robotics Summit & Expo subsequent week and Automate the week after that.
