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, in accordance with Robotiq Inc. The corporate immediately 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 actual 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 associated fee and complexity of anthropomorphic fingers.”
Based in 2008, Robotiq mentioned 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 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 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 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. 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 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 presents each pinch and encompassing grips, with stroke lengths of 85 and 140 mm (3.3 and 5.5 in.). It mentioned this permits 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 pressure distribution
- Micro-slip detection at 1000 Hz for steady, exact manipulation
- An built-in IMU (inertial measurement unit) for proprioceptive sensing and phone consciousness
“Not like different sensing mechanisms — optical or magnetic — we’re capacitor-based, like a smartphone touchscreen, which is well-established,” defined Kwiatkowski. “We give attention to 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 impression on stroke and attain, they usually characteristic sturdy cabling.
Robotiq touts sturdiness, scalability of EOAT
Robotiq mentioned that 1000’s 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 alternative value than anthropomorphic or DIY fingers, decreasing value and offering “a sensible path from lab prototype to large-scale robotic fleets.”
“We’re within the technique of doing assessments, however the threshold we’re seeking to match is our grippers’ lifecycles, which is on the order of thousands and thousands of cycles,” Kwiatkowski mentioned. “One other attention-grabbing aspect of our design is scalability. These sensors are usually not too complicated to fabricate, which is essential to us if we’re getting orders for a whole bunch of 1000’s 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 the very best sensor that matches essentially the most use instances.”

TSF-85 sensors to supply knowledge for bodily AI
Robotiq mentioned it shares finest practices for tactile knowledge dealing with, together with steerage on bias administration, normalization, and outlier detection, to assist groups generate constant, high-quality knowledge 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 obligatory for bodily AI datasets.
“It’s essential to just remember to’re aligning your knowledge assortment to the suitable duties so that you simply’re not losing time,” mentioned Kwiatkowski. She cited three mechanisms of the human sense of contact — sustained or quick adjustments in stress, vibration, and configuration of the fingers. These form notion of an object’s form in addition to greedy and manipulation capabilities.
The dearth of dependable knowledge throughout sensor modalities has hindered the event and manufacturing of bodily AI, in accordance with Robotiq. The corporate mentioned that its standardized {hardware} and tactile knowledge 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 knowledge as they construct towards generalized methods, Kwiatkowski mentioned. “On the Humanoids Summit, I heard how bodily AI is rising into operational AI, nevertheless it wants 99.9% reliability,” she recalled.
“To construct bodily AI that really works, you want {hardware} that may sense, reply, and study from each interplay,” mentioned Aleksei Filippov, head of enterprise improvement at Yango Tech Robotics. “That’s why we selected Robotiq. With Robotiq precision pressure management and dependable suggestions, we seize wealthy sensory knowledge 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 study quicker, function extra robustly, and scale past the lab,” mentioned the corporate, which is seeking to collaborate with builders.
