The story of the first torque-controlled lightweight robot?
And how the torque sensors made the jump from the German Aerospace Center's research institute to industry?
It's a real success story.
The German Aerospace Center, early 1990s.
A unique robot was being developed: It was the world's first torque-controlled lightweight robot - the DLR LBR I.
It soon became clear that torque control of drives would open up a whole range of applications for industry;
the technology used for the torque sensors would be needed.
In 2003, the LBR project managers founded the company Sensodrive to make the torque sensors suitable for use in industry.
With great success.
After all, the technology behind the Sensodrive torque sensors is elaborate and perfectly designed for use in torque-controlled drives.
Every year Sensodrive develops, produces and sells tens of thousands of torque sensors to renowned companies worldwide.
Get to know our Sensodrive torque sensors and their strengths.
And write history with us.
The basic principle of Sensodrive torque sensors is based on the resistance change of strain gauges. This is detected and interpreted with great accuracy.
The Sensodrive torque sensors offer all the characteristics needed for their specialist field – use in robot joints.
Such as their disk-shaped, sophisticated and compact design.
This makes it possible to fully integrate the torque sensors into joints and drives without taking up a significant amount of additional installation space.
What is more, the sensors barely add any extra weight.
Alongside the pure torque measurement function, the Sensodrive torque sensors also act as a bearing seat, sealing component and connection component.
The patented Sensodrive technology which compensates for interference from gears, bearings and external loads makes the Sensodrive torque sensors unique.
This is good news for precision and results. And, of course, for you.
Here at Sensodrive we have developed 50 different torque sensor types in the last 15 years.
During this time, experience has shown us that replacing an off-the-shelf torque sensor with a sophisticated and adapted product is the key to success.
Because every customer is different. Every sensor is different. And every requirement is different too.
This is why, when it comes to selecting the right product, we work closely with you, make changes if need be, and, in some cases, even develop completely tailor-made torque sensors.
Our slogan is: Individuality meets perfection.
Not only does this work, it generates enthusiasm.
You can see the specification range for our torque sensors here.
If you have different requirements, please contact us – we would be happy to advise.

At Sensodrive, the initial consultation is one of the most important steps.
We will discuss your requirements with you to gain an understanding of your application and the end product you need.
Together we will draw up an initial specification.
We then use this to determine whether an existing product variant is suitable, whether this needs to be adapted to meet your requirements or whether we need to develop a completely new sensor for you.
Thanks to our extensive experience and numerous completed projects, we are able to quickly draw up a quotation for you. Open and transparent.
If you choose to work with us, the development or adaptation work will be carried out according to defined and established processes.
We work closely with you throughout the entire process and always keep you in the loop about the current status.
Once the final specification has been approved, it is time for the FEM calculation and production.
All quality-relevant production steps, tests, calibration, and quality control are carried out in-house – ensuring high quality and short delivery times.
In the case of developments where the focus is on safety, we also work closely with the TÜV for example, create the required safety documents and carry out continuous load and failure insertion tests.
Optimum care from your enquiry to delivery.
Welcome to Sensodrive.
Sensodrive proves that innovations are at home not only in the industry, but also in the operating theater.

Ballbot didn't have any arms.
And then Sensodrive came along.
Would you put your hand in the way of a fast-moving robot? No one would, unless they knew very little about technology. Or would they?
