The Light Duo Mini smooth grippers are appropriate for meals dealing with. Supply: Ubiros
Dependable and delicate robotic greedy has lengthy been a problem, however Ubiros Inc. stated it may possibly remedy 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 smooth 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 smooth fingers and Light Professional with 4 fingers, in addition to Contact fashions for each that embody pressure management, half sensing/affirmation, and a low-power mode.
The Natick, Mass.-based firm stated 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.Okay., 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 must grow to be to make one thing like that?’” recalled Ondemir. “She stated ‘mechanical engineer.’”
“I grew up and have become an industrial engineer, however I’ve all the time been fascinated with mechanical techniques,” he informed 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 smooth robotics.
“We knew the constraints of pneumatics – precision is low, management is difficult, and the gear wanted to generate compressed air makes use of a number of electrical energy,” he stated. “After spending years within the lab, someday, he got here to me and stated, ‘Onder, I feel I’ve groundbreaking expertise for packaging and gripping on the whole, however I don’t need to run the corporate.’ Changing into the CEO was a no brainer to satisfy my want 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 shouldn’t be straightforward, as a result of such delicate meals objects are simply broken, Ondemir famous. Inflexible grippers sometimes don’t have ample sensitivity, and plenty of different firms are attempting to unravel issues resembling object detection and singulation, he stated.
“In farming, crops are being left to rot within the subject, which is a big waste,” added Ondemir. “A key barrier to getting automation is dealing with meals with a smooth contact.”
“However the actual downside we’re fixing is the employee scarcity,” he stated. “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 likewise accidents and at last the price of meals.”
Fingers versus suction cups
For many functions the place related objects are picked, suction cups are ample, stated Ondemir. Nevertheless, when there’s litter, 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 objects aren’t all the time appropriate for suction cups, Ondemir noticed.
“We’re proud to be one of many few firms growing particular person finger actuation quite than the entire hand,” he stated. “For singulation, it may possibly present alternate 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 stated. “Our expertise permits the finger unit to be versatile within the greedy route however very inflexible in twisting or bending sideways.”
Electrical end-of-arm tooling (EOAT) removes the necessity for tubes, valves, and compressors, he stated. Additionally, whereas pneumatic techniques must cycle to try one other grasp, an electrical one can reposition extra rapidly.
As well as, electrical grippers have prompt torque quite than needing to construct up stress for heavy payloads as hydraulic or pneumatic techniques do, stated 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 number of battery energy for autonomous cellular robots (AMRs) or drones, Ondemir stated.
Is Ubiros taking a look at cellular manipulation?
“We’ve had critical conversations with Staubli,” Ondemir replied. “Our gripper can 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 tendencies
Past cellular manipulation, Ondemir relied on his expertise in robotics improvement to touch upon present tech tendencies.
“Synthetic intelligence and machine studying enable us to implement predictive upkeep,” he stated. “Our electrical micro-controller is partly a system for pressure management and partly sensing. It’s in a position to accumulate temperature information from contained in the gripper, plus cycle counts and electrical present to construct fashions to foretell failures. That’s in our roadmap.”
Ubiros shouldn’t be presently working with digital twins as a result of it’s tough to know the precise deflection of soppy objects and the place one thing is in house, acknowledged Ondemir. Numerous analysis is being dedicated to this subject, he stated.
What about humanoids? “They’ll must have smooth parts for security and to protect in opposition to falling,” Ondemir stated. “This will probably be a key use for smooth robotics on the whole, not simply smooth grippers. As a result of we’re a derivative of WPI, we have already got smooth 3D sensors and a patented design of a smooth arm, however there’s lots nonetheless to do.”
Mechanical intelligence for manipulation
“The thought behind what we name ‘mechanical intelligence’ is that if you happen to can mechanically obtain one thing, you want costly programming, movement management, and imaginative and prescient much less,” stated 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 quite than hole ones that may be punctured or leak in in any other case sanitary environments.”
“Relying on the form of the thing, 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 pressure is distributed over a bigger space.”
Ubiros did construct some pressure management into its Light grippers, permitting customers to extend or lower stress, however it’s not needed normally, Ondemir stated.

Ubiros appears to be like forward
The Light gripper is initially tackling labeling and grading of tomatoes and cucumbers, and Ubiros has acquired a number of curiosity lately from bakeries, stated Ondemir. A hygienic gripper might then deal with dealing with of uncooked beef, poultry, and fish.
To that finish, Ubiros is searching for funding to make its grippers extra hygienic and sturdy in opposition to cleansing brokers. It’s engaged on safe-food dealing with certifications.
On the commercial facet, Ubiros is conducting a pilot with Mitsubishi to deal with quite a lot of objects and handle robotic greedy by means of Mitsubishi’s educate pendant.
“Down the street a couple of years, we need to focus extra on the info facet, permitting prospects to entry information by means of the tip effectors,” Ondemir stated. “We plan to finally deliver different patented applied sciences into the office – 3D sensors, haptic gloves, human-in-the-loop techniques, distant manipulation, and smooth arms.”
Ubiros will probably be on the Robotics Summit & Expo subsequent week and Automate the week after that.
