The on-board 68331 microprocessor permits autonomous or teleoperated navigation. Polaroid and Sharp PSD ultrasonic sonar sensors detect obstacles. The sensor head currently contains a metal detector; other sensors will be tested for the detection of plastic (minimum metal) mines.
At the entrance to EPFL.
In the weeds.
Mined terrain is often overgrown with dense vegetation. Pemex-BE's mountain
bike wheels allow it to move in high grass.
Climbing a pile of rocks.
With climbing cleats mounted on its wheels, Pemex-BE can climb irregular slopes
of 20° to 30°. It can also climb stairs. The wheels go first when
climbing to prevent the sensor package leaving the ground.
On the beach.
Philip Mächler holds the optional teleoperation control. Pemex-BE can
be teleoperated or can explore autonomously.
Going for a swim.
Equipped with optional water wings, Pemex-BE floats and swims.
This allows it to operate in environments such as rice paddies and,
on land, reduces the pressure on the ground when searching for
very sensitive pressure-triggered mines.
Packed for travel.
For transport, the wheels are removed and attached to the sides of the
main chassis. All components can be packed into a special rucksack.
Easily carried by one person.
Weighing a total of 20 kg including all accessories, Pemex-BE can be
easily transported by one person.
