Dependable and delicate robotic greedy has lengthy been a problem, however Ubiros Inc. stated it might 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 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 embody drive 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 purposes. 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 cherished 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 stated ‘mechanical engineer.’”

“I grew up and have become an industrial engineer, however I’ve all the time been fascinated with mechanical techniques,” he advised The Robotic Report. “I labored at an insurance coverage firm modeling the capability of techniques and demand forecasts, and I grew to become a vice chairman.”

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 tough, and the tools wanted to generate compressed air makes use of a whole lot of electrical energy,” he stated. “After spending years within the lab, at some point, 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.’ Turning 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 centered on meals dealing with.

Automating the dealing with of fruit and baked items will not be straightforward, as a result of such delicate meals objects are simply broken, Ondemir famous. Inflexible grippers usually don’t have ample sensitivity, and plenty of different firms try to resolve issues resembling object detection and singulation, he stated.

“In farming, crops are being left to rot within the discipline, which is a big 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 stated. “Harvesting and packing jobs aren’t attention-grabbing to individuals, and there are the problems of effectivity for the employer – most individuals work one shift – and in addition accidents and eventually the price of meals.”

Fingers versus suction cups

For many purposes the place related objects are picked, suction cups are ample, stated Ondemir. Nevertheless, when there’s muddle, resembling in e-commerce bins, or tight areas like bookshelves, choosing then requires a mixture of sensing to establish every object and the power to singulate that object.

Suction cups are versatile, however porous, dusty, fragile, or oddly weighted objects will not be all the time appropriate for suction cups, Ondemir noticed.

“We’re proud to be one of many few firms creating particular person finger actuation relatively than the entire hand,” he stated. “For singulation, it might present options in advanced choosing 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 problem 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 course 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 have to cycle to aim one other grasp, an electrical one can reposition extra shortly.

As well as, electrical grippers have on the spot torque relatively 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 cell manipulator is consumed by a suction cup, he asserted. Thus, Ubiros’ grippers might save a whole lot of battery energy for autonomous cell robots (AMRs) or drones, Ondemir stated.

Is Ubiros cell 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 cell manipulator that shall be demonstrated at Automate.

Ondemir surveys tech developments

Past cell manipulation, Ondemir relied on his expertise in robotics growth to touch upon present tech developments.

“Synthetic intelligence and machine studying enable us to implement predictive upkeep,” he stated. “Our electrical micro-controller is partly a system for drive management and partly sensing. It’s capable of 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 will not be presently working with digital twins as a result of it’s troublesome to know the precise deflection of soppy objects and the place one thing is in area, acknowledged Ondemir. Numerous analysis is being dedicated to this matter, he stated.

What about humanoids? “They’ll must have comfortable parts for security and to protect in opposition to falling,” Ondemir stated. “This shall be a key use for comfortable robotics on the whole, 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 rather a lot nonetheless to do.”

Mechanical intelligence for manipulation

“The concept behind what we name ‘mechanical intelligence’ is that should you 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 relatively than hole ones that may be punctured or leak in in any other case sanitary environments.”

“Relying on the form of the article, the gripper can robotically 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 drive is distributed over a bigger space.”

Ubiros did construct some drive management into its Light grippers, permitting customers to extend or lower stress, nevertheless it’s not essential typically, 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 whole lot of curiosity lately from bakeries, stated Ondemir. A hygienic gripper might then handle dealing with of uncooked beef, poultry, and fish.

To that finish, Ubiros is on the lookout for funding to make its grippers extra hygienic and strong in opposition to 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 Mitsubishi’s train pendant.

“Down the street just a few years, we need to focus extra on the info aspect, permitting prospects to entry information by the tip effectors,” Ondemir stated. “We plan to finally carry different patented applied sciences into the office – 3D sensors, haptic gloves, human-in-the-loop techniques, distant manipulation, and comfortable arms.”

Ubiros shall be on the Robotics Summit & Expo subsequent week and Automate the week after that.
