Bota Systems Rokubi
Bota Systems Rokubi is an ultra-light, compact 6-axis force/torque sensor designed for humanoid wrists, lightweight manipulators and quadrupeds. At a mass of only ~165 g and a height of ~22 mm, Rokubi measures three force components (Fx, Fy, Fz) and three moments (Mx, My, Mz) at up to 8 kHz sampling with on-board temperature compensation.
The sensor includes an integrated 6-DoF IMU for gravity and acceleration compensation, eliminating contact-measurement drift on mobile robots. Communication uses EtherCAT (1 kHz cycle) or CAN, with optional UART/RS-485 for research applications. Rokubi is used in ANYmal humanoids (research configurations), in teleoperated hands, and in selected Boston Dynamics Atlas research programs.

Force Torque Sensor · serves as: Sensing, Manipulation, Grasping.
Which group Bota Systems Rokubi belongs to and how it is built
A Force Torque Sensor measures linear forces and rotational torques at a single measurement point. In robotics, it is particularly important in manipulators, robot wrists, grippers, and human–robot collaboration systems. It enables force control, contact detection, load monitoring, and improved safety and manipulation precision. Sensors of this type are widely used in assembly, laboratory, and research applications.
