In context
In October 2024, collaborative robots were expanding into heavier payload classes, with Universal Robots introducing upgraded UR20 and UR30 models capable of handling 25 kg and 35 kg respectively. This shift demanded force-torque sensing solutions that could maintain precision at higher loads without adding integration complexity, making sensor design a critical enabler for advanced automation in material handling and manufacturing.
What was reported
Bota Systems unveiled the SensONE T80, a multi-axis force-torque sensor engineered for larger cobots. The sensor features ISO-9409-1-80-6-M8 flanges on both sides, directly matching the mounting flanges of Universal Robots' UR20 and UR30, eliminating the need for adapter plates. This simplifies integration for system integrators, reduces time to market, and minimizes overall assembly weight, allowing the robot's full payload capacity to be used for material handling rather than supporting tooling.
The sensor also includes an ISO 9409-1-50-4-M6 flange to accommodate third-party devices compatible with Universal Robots, facilitating new interface development. By removing adapters, the design also avoids potential stiffness compromises that could affect measurement accuracy. The SensONE T80 handles up to 80 Nm of torque, with peak-to-peak noise of 0.3 N for force and 0.012 Nm for torque, matching the precision of sensors used on lower-payload cobots.
According to Bota Systems, the sensor is particularly suited for heavy palletizing, tightening tasks (typically handled by the UR30), and welding (common for the UR20). Additional applications include large-scale sanding and polishing, precision mechanical assembly, and face matching/alignment of heavy workpieces in CNC loader operations. The sensor was showcased at RoboBusiness Conference & Expo in Santa Clara, CA, on October 16-17, 2024.
Why it mattered
The SensONE T80 addressed a growing need for high-payload force sensing in collaborative robotics, enabling precise force-controlled tasks in heavy-duty applications. By eliminating adapters and maintaining accuracy at higher loads, it supported the trend toward larger cobots taking on more demanding industrial roles, potentially accelerating adoption in sectors like automotive, metal fabrication, and logistics.
“This sensor, featuring ISO flanges on both sides, is a perfect fit for the UR20 and UR30 models.”
