Advanced Force and Torque Sensing for Collaborative Robots

The OnRobot Hex 6-Axis Force / Torque Sensor gives collaborative robots the sense of touch needed for advanced automation tasks. Designed for precision, flexibility, and fast deployment, this innovative sensor improves the performance of polishing, sanding, assembly, insertion, and deburring applications across many industries.

At PSI, we provide advanced end of arm tooling solutions that help manufacturers improve quality, productivity, and consistency. The Hex 6-Axis Force / Torque Sensor allows cobots and industrial robots to perform delicate and highly accurate tasks that would otherwise require skilled manual labour.

By adding intelligent force control to your robotic system, you can achieve smoother movements, more accurate assembly, and better surface finishing results while reducing downtime and waste.

What Is the Hex 6-Axis Force / Torque Sensor?

The OnRobot Hex Sensor is an advanced force and torque measurement device designed for collaborative robots and industrial robot arms. It accurately measures forces and torques along all six axes, giving the robot precise feedback during operation.

This sensing technology allows the robot to react intelligently to pressure, resistance, and movement. As a result, the robot can adapt to uneven surfaces, delicate components, and complex assembly tasks with exceptional accuracy.

The sensor works seamlessly with major robot brands, including Universal Robots cobots. It integrates quickly into existing automation systems with minimal disruption.

The Hex Sensor is available in several models including:

  • HEX-E High Precision
  • HEX-H Low Deformation
  • HEX-E QC
  • HEX-H QC

Each version supports demanding industrial applications where precision and repeatability matter most.

Why Choose the OnRobot Hex Sensor?

Many manufacturing processes require more than simple positioning. In applications such as polishing, grinding, insertion, or precision assembly, robots must apply the correct amount of force at all times.

The Hex 6-Axis Force / Torque Sensor delivers that control.

Unlike traditional robotic systems, the Hex Sensor allows the robot to feel how much pressure it applies during movement. Consequently, manufacturers achieve better accuracy, fewer defects, and more consistent production quality.

The sensor helps automate tasks that previously required skilled operators. This improves productivity while reducing labour demands and repetitive strain injuries.

The sensor also includes advanced software features such as:

  • Path recording
  • Force control
  • Hand guiding
  • Insertion optimisation
  • Crash detection

As a result, even complex automation projects can be deployed quickly and efficiently.

Improve Surface Finishing Applications

Surface finishing tasks require consistent pressure and smooth movement to achieve high-quality results. Therefore, force control plays a vital role in applications such as:

  • Polishing
  • Sanding
  • Deburring
  • Grinding
  • Surface preparation

The Hex Sensor maintains constant force and speed while the robot moves across the workpiece. Consequently, the finishing tool follows surface contours accurately and consistently.

This level of precision helps manufacturers reduce scrap, improve surface quality, and achieve flawless finishes across every production cycle.

The sensor reduces variation between operators, ensuring repeatable results throughout production.

Optimise Assembly and Insertion Tasks

The Hex 6-Axis Force / Torque Sensor also performs exceptionally well in assembly and insertion applications.

Many assembly processes require precise positioning and controlled pressure. Without accurate force feedback, components may become damaged or incorrectly fitted.

However, the Hex Sensor enables the robot to detect contact instantly and respond with precision. As a result, insertion tasks become faster, smoother, and more reliable.

Applications include:

  • Component insertion
  • Pin insertion
  • Connector assembly
  • Precision fitting
  • Press applications
  • Electronics assembly

Because the sensor measures forces along all six axes, the robot can compensate for slight misalignments during insertion. Consequently, manufacturers experience fewer defects and improved product quality.

Easy Programming and Fast Deployment

One of the biggest advantages of the OnRobot Hex Sensor is its ease of use.

The integrated graphical user interface allows operators to program applications quickly without advanced robotics knowledge. Additionally, the intuitive software reduces commissioning time significantly.

Many applications can be configured and running within hours rather than days.

The sensor also supports easy hand guiding and path recording. Therefore, operators can physically guide the robot through complex movements and record the exact path instantly.

This feature simplifies programming for:

  • Polishing paths
  • Sanding contours
  • Assembly movements
  • Surface tracking
  • Precision finishing

Advanced Optical Sensor Technology

The Hex Sensor uses unique optical-based sensing technology. Unlike traditional strain gauge systems, this advanced design provides exceptional durability and resistance to sudden shocks.

The sensor performs reliably in demanding industrial environments.

The technology also delivers extremely accurate force and torque measurements across all six axes (Fx, Fy, Fz, Tx, Ty, Tz ).

This high level of accuracy allows robots to perform delicate operations with confidence and repeatability.

The robust sensor design helps reduce maintenance requirements and improve long-term reliability.
