Steering Robots

Steering robot and path-following being used on an ice track.

AB Dynamics has the widest range of steering robots in the world; whatever your requirements are, we can offer you the best solution. Our robots are the industry reference point – the 25 most successful vehicle manufacturers in the world use them. 

A steering robot applies accurate and repeatable inputs to a vehicle’s steering, allowing the test engineer to completely remove the variability that comes from a human driver. The range includes robots specifically designed for vehicle dynamics, durability testing and ADAS development, with models that exceed the requirements for tests such as the NHTSA Fishhook, FMVSS 126 / Reg13H sine-dwell and many other industry standards.

Our steering robots are engineered to the highest standards to ensure that they are reliable - the first ever robot was supplied in 1997 and is still in use today.

Perfect Repeatability

Highly repeatable, perfectly accurate

The graph shows raw, unfiltered steering angle data from a sine-sweep test, performed six times with the runs overlaid. AB Dynamics’ advanced motion control technology guarantees total repeatability, with a perfect blending of amplitude and frequency.

Direct-drive motors

The SR35, SR60, SR60 Torus and SR150 use advanced direct-drive motors which require no gears or clutch. As a result, they are quieter, smoother and have the lowest possible inertia*.

Testing the Torus with an airbag deployment by ABD

Airbag compatible

Several of our steering robots have a key feature – the hole in the middle. This allows the robot to be attached to the vehicle’s steering wheel without disabling or removing the airbag. The hollow-centre range includes the following models: SR15, SR15 Orbit, SR60 Orbit, SR60 Torus. Our robots have been tested to ensure they allow the safe deployment of a typical steering wheel airbag, as shown in this video.
