UFO is an UltraFlat Overrunable robot used for

Advanced Driver Assistance Systems (ADAS)

testing. Because of its 2D motion and its

programmable speed profiles it allows testing of

real world scenarios.

Its very stable structure can be overrun by test

vehicles – without damaging them – and the

target will be pushed away from the UFO. UFO is

designed from the beginning for crash and post-

crash scenarios and not only pre-crash.

Your advantages

| Different Targets � maximum usability

| Removable ramps and battery

� fast and easy transportation

| Transp. handles � very easy handling

| Smart Software � fast and easy to use

| Ultra flat design � no damage to test car

| Robust 3D dummy � no need to

reassemble after crash

UFO-Standard / UFO-High performance

The UFO is monitored and operated using a

wireless receiver. The on-board processor

connected to the inertial and dGPS

platform is controlling the UFO following the

pre-programmed target trajectories.

Free trajectories can be programmed easily

and user friendly. This allows a very easy and

fast setup and change of trajectories.

The start can be triggered by light gates or

position information from the test vehicle.

The four wheel concept with its front steer

axle and the rear traction axle can be used

for real and stable vehicle motions.

The electric engines are powered by fast

swappable batteries. Mechanical brakes

allow high and precise decelerations.

Removable ramps and battery allow easy

transportation and maintenance due to

reduction of size and weight. A fast wheel

change concept allows wheel changes in

shortest time.

Not all parameters can be reached simultaneously * recommended test scenario speed: 40kph ** depending on aerodynamic of dummy
