The wheels are custom built per order, expect a maximum lead time of 60 days.
•All metallic wheel,
•Passive stiffness variability.
•Tracked grouser rim.
•250N maximum operational load.
•800N maximum static load.
•Easy motor implementation.

This version of the wheel comes without internal motor. Motorization can be easily achieved from the front interface.
The wheel is the closest equivalent of a flight wheel that can survive the lunar environment. Operating your rover with these wheels will give you the closest possible behavior of your machine on a lunar landscape. The performance of the wheel is astonishing, even when compared with rubber tires. The wheel actually behaves like a caterpillar, embracing terrain irregularities and absorbing shocks. The resulting operation is extremely smooth.
The wheel comes in 2 spring stiffness options: 06 and 08.
Both 06 and 08 wheels also automatically vary their stiffness during operation: The stiffness increases when the wheel generates higher torque, in connection with the ground. That is, the harder the soil, the higher the stiffness the wheel can reach (within a predefined range). This further increases the adaptability and efficiency of the wheel.
The 06 wheel is designed to carry a smaller load (150 N) compared to the 08 type of wheel, that can carry a 250 N load. The 06 wheel is more suitable for very loose (GRC-1) type of soils, while the 08 wheel is designed for soils bearing higher ground pressures.
The wheels have a preferential direction of motion. This is due to the automatic stiffness adaptation, which will operate correctly if the wheel is operated along its preferential direction of motion. We recommend to apply this direction as the forward direction of motion of your rover. Therefore, for use on a 4 wheel rover, you must use 2 wheels with clockwise preferential direction of motion and 2 wheels with counter-clockwise preferential direction of motion. The preferential direction of motion is shown on each wheel cover (see in manual).
