Maximum safety for human-robot collaboration

Sensodrive torque technology is used in the cobots of many renowned industrial and medical robot manufacturers. We are making this innovative technology available in a complete drive for the first time with SensoJoints, offering you the highest level of safety for your robotics solutions.

Fully safety certified

SensoJoints are already certified in accordance with all key international safety standards - such as e. g: ISO 13849, IEC 62061, IEC 61508 and DIN ISO/TS 15066 (from 2024). So there's no need to go through any more lengthy certification processes.

Maximum safety for users humans

Thanks to market-leading sensor technology and precise, highly safe control technology, SensoJoints offer maximum reliability in every respect so that robots and humans can work together safely without protective fences.

Maximum production reliability

Sensodrive only uses high-quality components that are perfectly compatible with each other. SensoJoints are therefore completely maintenance-free and set new standards in terms of their durability.

 

For maximum safety in industrial robotics and medical technology - the SensoJoint safety functions

STO - Safe Torque Off

Safe Torque Off interrupts the power supply to the drive while the brake is applied. The joint controller is deactivated and the joint is mechanically stopped.The STO function ensures that no torque can act on the motor and is therefore used in industrial machines, robots and force feedback solutions for emergency stop and safety stop functions.

SBC – Safe Brake Control

Safe Brake Control (SBC) ensures that the brakes are locked when Safe Torque Off (STO) is activated. This ensures that lifted loads are braked in good time and do not drop. This is how SBC ensures the reliable implementation of emergency and safety stops in industrial machines, robots and force feedback solutions.

SBT – Safe Brake Test

After appropriate implementation in the safety control system, the Safe Brake Test (SBT) safety function ensures that the brakes can apply the required holding torque at all times by cyclically checking them. In combination with Safe Torque Off (STO) and Safe Brake Control (SBC), it guarantees an absolutely safe braking and stopping system.

SS1 – Safe Stop 1

If the drives were simply switched off, they would run down, which could lead to hazards. With the help of the Safe Stop 1 (SS1) safety function, the SensoJoint drive is therefore brought to a controlled standstill. As soon as the motor movement stops, the STO function is automatically triggered. This allows the drive to be fast and safely stopped and the brake is noticeably protected.

SS2 – Safe Stop 2

The SensoJoint drive is brought to a standstill in a controlled manner and remains in control even when at a standstill. By keeping the drive powered, the position can be held precisely, and it is quicker to move on after the safety stop than with other stop functions.

SOS – Safe Operating Stop

With the Safe Operating Stop (SOS) safety function, the SensoJoint reliably monitors the holding of a position (for example after activation of the SS2 function). The drive may only move within a precisely defined position window. If the permissible position tolerance is exceeded, a suitable error reaction takes place, e.g. activation of the STO function.

Safe Position (SP) & Safely Limited Position (SLP)

These two safety functions monitor the robot arm's
positioning. SP uses FSoE (FailSafe over EtherCAT)
to ensure the safe provision of the SensoJoint's
output position to the higher-level safety controller
(FSoE master).
Based on this information, the SLP carries out a
safe limitation of the axis and spatial movements.
In addition, further position-dependent safety
functions can be activated if required.

Safe Velocity (SV) & Safely Limited Speed (SLS)

These safety functions ensure that the speed is
monitored. SV provides precise measurement data
of the respective output speed via FSoE, which is
processed by the higher-level safety control.
Based on the measurement data, the robot speed
can be optimally limited by SLS during axis and
spatial movements – for example in robots and
force feedback products.

 

Safe Torque (ST) & Safely Limited Torque (SLT)

The ST and SLT safety functions enable reliable
monitoring of a robotics solution's forces and torques
(axis and spatial movement). ST sends the SensoJoint's
precise output torque measurement data via FSoE
to the safety control. Based on this information,
SLT ensures safe force and torque limitation for all
movements.

 

Impressive quality made in Germany

High-quality lightweight materials, market-leading torque sensors and precise finishing ensure reliable product quality that is worth the investment. SensoJoints are extremely robust and completely maintenance-free.

Ultra-light and compact

Size and weight are reduced to an absolute minimum thanks to the perfect compatibility of all components and the use of sturdy, lightweight materials.

Highly precise

The innovative Sensodrive torque control ensures that motions are executed with maximum precision – without any oscillation.

Fast and powerful

Particularly powerful motors and market-leading gears with output bearing enable safe and reliable power transmission.

 

 

Advanced Control Algorithms

Advanced Position Control

The active vibration damping reliably prevents unwanted oscillations and, with precise friction compensation, enables fine adjustment of the smallest vibrations – even with higher inertias and loads. SensoJoints are thus guaranteed to securely hold a defined position, even when affected by disturbing forces, e.g. for the vibration-free positioning of surgical microscopes.

Advanced Velocity Control

The precise speed control ensures smooth, steady control even at low speeds of less than 1°/s. Its active friction compensation reliably prevents the occurrence of stick-slip effects as well.

Advanced Torque Control

SensoJoints impress with their highly precise and dynamic torque control at the output:

  • Active friction compensation
  • Active motor ripple compensation
  • Active gearbox wobble compensation
  • Motor inertia compensation for even more dynamics

Optimum safety for all areas of application


Thanks to their comprehensive safety functions, SensoJoint complete drives meet all the requirements of safety integrity level SIL3/PLe. They are already fully safety-certified* in accordance with IEC 61508, IEC 62061 as well as ISO 13849, thus saving you significant time and costs when meeting the requirements of ISO 10218 and ISO/TS  15066 compared to developing your own solutions.

  • Develop cobots and medical robots in under 5 months.
  • Halve your time-to-market.
  • Save 7-figure development and certification costs.
  • Implement ISO 10218 and ISO/TS 15066 up to 4 times faster.

The efficient alternative – the SensoJoint basic design

For use in less safety-critical areas, our SensoJoint complete drives are also available in a
basic version with only two safety functions – the efficient solution for all applications that
do not require extended safety certification to SIL3/PLe level.

* Certification process completion expected in Q1 2024.
