Rending of the TSF-85 tactile sensor fingertips on the 2F-85 Adaptive Gripper. Supply: Robotiq
Robotic finish effectors don’t must be humanoid to be extra delicate and efficient, in keeping with Robotiq Inc. The corporate in the present day launched the TSF-85 tactile sensor fingertips for its 2F-85 Adaptive Gripper. It stated that its built-in sensing allows robots to reliably really feel, perceive, and work together with the world at scale.
“Bodily AI calls for greater than intelligent algorithms—it calls for dependable interplay with the actual world,” said Vincent Duchaine, chief expertise officer for synthetic intelligence at Robotiq. “By combining adaptive gripping with high-frequency tactile sensing, we’re giving robots the sense of contact and management they should generalize throughout objects, duties, and environments with out the fee and complexity of anthropomorphic palms.”
Based in 2008, Robotiq stated it constructed the TSF-85 on years of analysis and discipline expertise, with greater than 23,000 grippers deployed worldwide. The Lévis, Quebec-based firm stated main AI labs and producers use its merchandise to “bridge the hole between digital intelligence and bodily actuality.”
Robotiq commercializes college R&D
“Tactile sensing has been in academia for a very long time,” famous Jennifer Kwiatkowski, an AI specialist at Robotiq. “Robotics corporations are realizing the boundaries of what imaginative and prescient can do for planning, navigation, and manipulation when it comes to their robotic notion stacks.”
Robotiq’s tactile sensor got here out of analysis that Kwiatkowski labored on on the École de technologie supérieure (ETS) in Montreal, she instructed The Robotic Report.
“My analysis was on grasp stability prediction utilizing these sensors and AI,” Kwiatkowski stated. “There have been different experiments round object and texture recognition, in addition to detecting if there’s a crack in a chunk. For those who’re squeezing totally different objects, are you able to acknowledge them?”
“Robotiq acknowledged that we had one thing, having been concerned with end-of-arm tooling [EOAT] for 17 years,” she added. “The gripper is the way in which that the robotic interacts with the world, so your entire notion on the finish of the arm is what makes your robotic helpful.”
2F-85 gripper designed for sensitivity, simplicity
Whereas parallel grippers depend on exact positioning and inflexible alignment, Robotiq stated its 2F-85 EOAT presents each pinch and encompassing grips, with stroke lengths of 85 and 140 mm (3.3 and 5.5 in.). It stated this enables the gripper to adapt to an object’s form, reduces grasp planning complexity, and minimizes reliance on unobstructed imaginative and prescient, making it appropriate for dealing with a variety of objects.
Robotiq listed the next capabilities:
- A 4×7 static taxel grid to observe drive distribution
- Micro-slip detection at 1000 Hz for secure, exact manipulation
- An built-in IMU (inertial measurement unit) for proprioceptive sensing and make contact with consciousness
“Not like different sensing mechanisms — optical or magnetic — we’re capacitor-based, like a smartphone touchscreen, which is well-established,” defined Kwiatkowski. “We deal with having good integration of the sensor into the robotic hand, which must be dependable within the warehouse.”
The tactile-enabled 2F grippers combine into present robots utilizing native RS-485 communication and a USB conversion board, stated Robotiq. The tactile fingertips are designed to protect grip mechanics with minimal influence on stroke and attain, they usually characteristic strong cabling.
Robotiq touts sturdiness, scalability of EOAT
Robotiq stated that hundreds of its grippers are already working in demanding analysis and industrial environments worldwide. It claimed that its grippers have a decrease invoice of supplies (BOM) and substitute price than anthropomorphic or DIY palms, lowering price and offering “a sensible path from lab prototype to large-scale robotic fleets.”
“We’re within the strategy of doing assessments, however the threshold we’re seeking to match is our grippers’ lifecycles, which is on the order of hundreds of thousands of cycles,” Kwiatkowski stated. “One other fascinating component of our design is scalability. These sensors are usually not too advanced to fabricate, which is vital to us if we’re getting orders for tons of of hundreds of grippers.”
“Articulated palms are tougher to regulate and have extra failure modes,” she stated. “Humanoid palms are very cool, however they’re extra of a 10-year play, whereas we’ll be able to ship models within the coming months and iterate towards the very best sensor that matches essentially the most use circumstances.”

TSF-85 sensors to supply information for bodily AI
Robotiq stated it shares greatest practices for tactile information dealing with, together with steering on bias administration, normalization, and outlier detection, to assist groups generate constant, high-quality information for mannequin coaching. It asserted that its sensors allow robots to grasp contact geometry, detect incipient slip, and enhance generalization throughout numerous objects, all of that are crucial for bodily AI datasets.
“It’s vital to just remember to’re aligning your information assortment to the suitable duties so that you just’re not losing time,” stated Kwiatkowski. She cited three mechanisms of the human sense of contact — sustained or quick modifications in strain, vibration, and configuration of the palms. These form notion of an object’s form in addition to greedy and manipulation capabilities.
The dearth of dependable information throughout sensor modalities has hindered the event and manufacturing of bodily AI, in keeping with Robotiq. The corporate stated that its standardized {hardware} and tactile information present a base for reinforcement studying, vision-language-action (VLA) fashions, and imitation studying.
Regardless of how good simulations could also be, builders nonetheless want real-world information as they construct towards generalized techniques, Kwiatkowski stated. “On the Humanoids Summit, I heard how bodily AI is rising into operational AI, however it wants 99.9% reliability,” she recalled.
“To construct bodily AI that actually works, you want {hardware} that may sense, reply, and be taught from each interplay,” stated Aleksei Filippov, head of enterprise growth at Yango Tech Robotics. “That’s why we selected Robotiq. With Robotiq precision drive management and dependable suggestions, we seize wealthy sensory information from each grasp.”
“By giving robots a dependable sense of contact that mixes with adaptive gripping and industrial-grade reliability, Robotiq allows the following technology of bodily AI techniques to be taught quicker, function extra robustly, and scale past the lab,” stated the firm, which is seeking to collaborate with builders.
