Study on an 8-Wheel Suspension to Enhance the Hill-Climbing Performance for a Planetary Exploration Rover
Planetary exploration rovers are likely to make a trip on a winding and sloping road of irregular surfaces to the destination in order to accomplish scientific missions.

| description | Planetary exploration rovers are likely to make a trip on a winding and sloping road of irregular surfaces to the destination
in order to accomplish scientific missions. One of the key technologies for rovers is a suspension for traveling and
performing exploration missions; the suspension is an essential area of technology for a stable movement of a rover. In this
study, an 8-wheel suspension is designed to enable efficient climbing of slopes on a passage to the destination. For the two
front wheels among the eight wheels, the moment at the pivot connecting two wheels is derived when the distance between
the wheels and the torque of wheels are same. A test experiment was performed to compare the magnitude of moment
according to the change in tilt angle and the position of the pivot. Finally, a suspension design considering the position of
the pivot was proposed to enhance the hill-climbing performance. |
