How was the design of the rocker-bogie system finalized? Specifically, how were the various arm lengths and pivots points chosen to maximize the rovers mobility?
The footprint of the rover was determined by the size of the vehicle which could be safely stowed on the lander petal. Within this constraint, the rocker-bogie system for Sojourner was adapted from the system implemented on Rocky 4 (an early technology demonstration vehicle). That system (6 evenly spaced wheels, allowing for more than a wheel diameter of obstacle traversal, nearly symmetrical in capability for forward/backward motions, unusual rock configuration needed for hangup, etc.) met all requirements for the Sojourner vehicle mission. Pivot joint stops were determined by potential for interference with other portions of the vehicle structure (solar panel, wire bundles, etc.). Back to the top of the page.
