MAGUS

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.

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.

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.

Our Range of Steering Robots

SR15

Low-cost geared model

Ideal for ADAS testing and driverless use

20Nm maximum torque

The SR15 was designed to meet the requirement for a low-cost steering robot which could easily attach to a vehicle\'s steering wheel without removing the airbag. It\'s a very popular choice for ADAS testing and is also well-suited to durability applications.

SR15 Orbit

Geared motor which fits behind steering wheel

Improved driver ergonomics compared to SR15

20Nm maximum torque

Using the same lightweight motor as the SR15, combined with the split-gear design of the SR60 Orbit, this model can be installed behind the steering wheel rim for excellent driver ergonomics, or in front of the rim where the dash or stalks would otherwise interfere.

SR35

Ultra-low inertia and friction

Replaces the SR30 model

43Nm maximum torque

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.

SR60

Ideal for fishhook, sine-dwell and other high-torque tests

Best-selling model

70Nm maximum torque

Designed specifically for high-power tests such as the fishhook and sine-dwell, the SR60 is our best-seller, used worldwide by OEMs and test houses. With a maximum speed of over 2500˚/s, the SR60 can apply steering inputs that no driver could do.

SR60 Orbit

Installs without removing airbag

Similar performance to SR60

Ideal for ESC testing

The SR60 Orbit offers a similar performance to the SR60 but can be installed in vehicles without removing the steering wheel airbag. As with any geared steering robot, it is not as quiet or smooth as our range of direct-drive motors.

SR60 Torus

Unique, patented design with direct-drive hollow motor

Ideal for fishhook, sine-dwell and other high-torque tests

85Nm peak torque

Perhaps the ultimate steering robot, the Torus offers the best of both worlds. Its hollow centre means that it can be installed without removing the airbag, while also being quieter and smoother than any geared robot. The Torus is protected by international patents.

Halo

Lowest inertia and friction of any hallow-centre SR on the market. Ultra-low profile with motor height of just 78mm.

Peak Torque at 90 Nm

Ideal solution for New Euro NCAP Emergency Steering Support (ESS) Procedure.

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.

SR150

Designed for steering homologation tests in trucks and buses

160Nm maximum torque

The SR150 was designed for testing power-failure situations in trucks and buses - a requirement for homologation - meaning that is has the highest torque of any AB Dynamics robot. It can also be used for a wide range of other handling tests.
