Pedal Robot Test System
Our pedal robots can be used on their own or combined with a steering robot to provide full control of a vehicle. The brake robot range is used by vehicle manufacturers, brake and tyre suppliers to test and validate vehicle braking performance.
The Combined Brake and Accelerator Robot (CBAR) is the most widely used pedal robot, allowing precise vehicle speed control as well as brake or throttle inputs. The CBAR can be upgraded with a backup safety brake system for use in driverless testing.

The range also includes a throttle robot and a clutch robot which can be combined with a gear-shift robot. As with all AB Dynamic's driving robots, pedal robots can be quickly installed in almost any vehicle, making them ideal for benchmarking competitor vehicles.
Our pedal robots allow for a variety of control modes :
Vehicle speed
Brake pedal force
Pedal travel
Vehicle deceleration
Brake line pressure
Engine RPM
CBAR - an essential tool in the development of test procedures
The AB Dynamics CBAR is the pedal robot of choice for the organisations that determine tomorrows test procedures. Tests can be programmed to include accurate control of the vehicles speed in combination with other pedal actions, allowing the creation of complex procedures. All of the seven Euro NCAP labs use the CBAR, along with NHTSA in the USA and Transport Canada.
Compatible with a driver
The mechanical design of our pedal robots (like all of our driving robots) is based upon the concept of allowing a human driver to operate the vehicle safely and comfortably from the drivers seat, even with the robots installed. The driver is always able to override the robots and take control of the vehicle if necessary.
Our Range of Pedal Robots
CBAR600
ADAS testing and durability
Max brake force 750N
Upgradeable for driverless testing
The CBAR600 is the best-selling of our range of pedal robots, used in a wide range of applications. Its the standard choice for AEB testing and other ADAS tests, and also the easiest way to add speed control to a vehicle dynamics test.
CBAR1000
Versatile robot for brake tests and speed control
Max brake force 1300N
Upgradeable for driverless testing
Where more brake force is needed, choose the CBAR1000 – the big brother of the CBAR600. It has enough power for aggressive brake testing, and the CBAR1000 is also suitable for general speed control use and ADAS testing.
AR1 accelerator robot
Controls throttle position or vehicle speed
Can be combined with BR1000
Max force 150N
The AR1 was the original tool for controlling throttle position and vehicle speed (before the CBAR was designed). It is the lowest-cost way of adding simple speed control to a steering robot system and can also be combined with a BR1000.
RBR1500
Ideal for aggressive brake stop testing
Highest speed and force from rotary actuator
Max force 1600N
Tests such as the AMS Brake Fade procedure require a very high pedal force and apply rate. The RBR1500 is the perfect tool for the job, with an ultra-powerful rotary actuator capable of pushing the pedal faster and harder than most human drivers.
