Original Bota Systems 6-Axis Force Torque Sensor - Ultra-Lightweight & Integrated
Bota Systems, a spin-off from the Robotic Systems Lab at ETH Zurich, is a pioneer in highly integrated force-sensing solutions for the next generation of collaborative robots and advanced research platforms. Their 6-axis Force/Torque (F/T) sensors break the limitations of traditional systems by embedding all necessary electronics—including amplifiers and data acquisition—directly into the compact sensor housing. This eliminates the need for bulky external interface boxes. By integrating a 6-axis F/T sensor with a 6-axis IMU (Inertial Measurement Unit), Bota Systems provides a full 12-degree-of-freedom (DoF) perception in a package weighing just over 100 grams. It is the gold standard for surgical robotics, humanoid wrists, and legged robot balance control.
Product Highlights
Fully Integrated Electronics: Amplifiers, data acquisition, and communication circuits are all built-in, enabling true single-cable "Plug & Play" functionality without external hardware.
Ultra-Lightweight Design: Models like the Rokubi weigh as little as 120g, significantly reducing the payload at the robot's end-of-arm and improving dynamic response.
12 Degrees of Freedom (12 DoF): Beyond 6-axis force/torque, the built-in high-precision IMU provides synchronized acceleration and angular velocity data.
Ultra-High Refresh Rate: Supports sampling frequencies up to 1000 Hz (EtherCAT) or 800 Hz (USB/Serial), meeting the demands of high-performance closed-loop force control.
Extreme Compactness: The flat, low-profile design is ideal for integration into dexterous hands, exoskeletons, and space-constrained joints of micro-robots.
Extensive Open-Source Support: Features deeply integrated ROS/ROS2 drivers and Python libraries, making it the top choice for academia and high-tech startups.

Frequently Asked Questions
Q: Why does Bota Systems not require an external interface box?
A: We use advanced System-on-Chip (SoC) technology to compress all signal conditioning and processing circuits directly into the mechanical structure of the sensor.
Q: What is the benefit of the built-in IMU?
A: The IMU (accelerometer + gyroscope) monitors the sensor's motion in real-time. This allows force-control algorithms to compensate for inertial forces and gravity during movement, providing the "true" contact force.
Q: Which robot brands does the SensONE support?
A: The SensONE is optimized for Universal Robots (UR) with a dedicated URCaps plugin, but it also natively supports protocols for Yaskawa, KUKA, ABB, and more.
Q: Is the sensor crash-resistant? What is the overload protection?
A: All sensors feature high overload protection (typically 300%-500% of rated capacity). Precision will not be affected by minor emergency stop collisions within these limits.
Q: How is the sensor calibrated?
A: Every sensor is precision-calibrated at our Swiss factory. Users can read decoupled physical units (N and Nm) directly via the software interface.
Q: What is the typical lead time?
A: Common models (SensONE, Rokubi) typically ship in 2-4 weeks. Specialized interfaces or high-sensitivity versions may take 6-8 weeks.
