Rending of the TSF-85 tactile sensor fingertips on the 2F-85 Adaptive Gripper. Supply: Robotiq
Robotic finish effectors don’t should be humanoid to be extra delicate and efficient, based on Robotiq Inc. The corporate as we speak launched the TSF-85 tactile sensor fingertips for its 2F-85 Adaptive Gripper. It mentioned 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 true world,” acknowledged Vincent Duchaine, chief know-how 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 fingers.”
Based in 2008, Robotiq mentioned it constructed the TSF-85 on years of analysis and subject expertise, with greater than 23,000 grippers deployed worldwide. The Lévis, Quebec-based firm mentioned 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 bounds of what imaginative and prescient can do for planning, navigation, and manipulation by way of 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 informed The Robotic Report.
“My analysis was on grasp stability prediction utilizing these sensors and AI,” Kwiatkowski mentioned. “There have been different experiments round object and texture recognition, in addition to detecting if there’s a crack in a bit. If you happen to’re squeezing completely 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 best way that the robotic interacts with the world, so all your 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 mentioned its 2F-85 EOAT gives each pinch and encompassing grips, with stroke lengths of 85 and 140 mm (3.3 and 5.5 in.). It mentioned this enables the gripper to evolve 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 watch drive distribution
- Micro-slip detection at 1000 Hz for steady, 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 concentrate on having good integration of the sensor into the robotic hand, which must be dependable within the warehouse.”
The tactile-enabled 2F grippers combine into current robots utilizing native RS-485 communication and a USB conversion board, mentioned Robotiq. The tactile fingertips are designed to protect grip mechanics with minimal influence on stroke and attain, they usually function strong cabling.
Robotiq touts sturdiness, scalability of EOAT
Robotiq mentioned 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 fingers, decreasing price and offering “a sensible path from lab prototype to large-scale robotic fleets.”
“We’re within the means of doing assessments, however the threshold we’re seeking to match is our grippers’ lifecycles, which is on the order of tens of millions of cycles,” Kwiatkowski mentioned. “One other fascinating aspect of our design is scalability. These sensors should not too advanced to fabricate, which is essential to us if we’re getting orders for lots of of hundreds of grippers.”
“Articulated fingers are tougher to manage and have extra failure modes,” she mentioned. “Humanoid fingers 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 one of the best sensor that matches essentially the most use circumstances.”

TSF-85 sensors to offer information for bodily AI
Robotiq mentioned 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 various objects, all of that are needed for bodily AI datasets.
“It’s essential to just remember to’re aligning your information assortment to the suitable duties so that you just’re not losing time,” mentioned Kwiatkowski. She cited three mechanisms of the human sense of contact — sustained or quick modifications in strain, vibration, and configuration of the fingers. These form notion of an object’s form in addition to greedy and manipulation capabilities.
The shortage of dependable information throughout sensor modalities has hindered the event and manufacturing of bodily AI, based on Robotiq. The corporate mentioned that its standardized {hardware} and tactile information present a base for reinforcement studying, vision-language-action (VLA) fashions, and imitation studying.
Irrespective of how good simulations could also be, builders nonetheless want real-world information as they construct towards generalized methods, Kwiatkowski mentioned. “On the Humanoids Summit, I heard how bodily AI is rising into operational AI, but it surely 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,” mentioned 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 subsequent era of bodily AI methods to be taught quicker, function extra robustly, and scale past the lab,” mentioned the firm, which is seeking to collaborate with builders.
