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.
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.
The SR35, SR60, SR60 Torus, Halo 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*.
*SR35 rotational inertia is 0.0074kgm2 excluding steering wheel
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 and Halo. Our robots have been tested to ensure they allow the safe deployment of a typical steering wheel airbag, as shown in this video.
The SR35 replaces the hugely successful SR30 - the original steering robot. It uses a lighter, thinner version of the SR60 motor to provide ample performance for typical driving scenarios and vehicle dynamics tests (but isn’t suited to fishhook or sine-dwell testing). It has the lowest rotational inertia of our range.
The unique patented design with direct-drive hollow motor allowing installation without removing the airbag. Using a carbon fibre steering rim and innovative wrap-around design. The Halo delivers both the high torque necessary to evaluate limit handling as well as precision, light-touch control needed for the latest ADAS tests.
