Locomotion

SEAR belongs to the class of wheeled robots for planetary exploration. The drivetrain consists of eight wheels passively suspended on a Rocker-bogie system. Both rockers are connected to each other and to the chassis through an averaging mechanism. The rockers and the bogies are machined from an aluminum alloy.
