  Semi or completely autonomous unmanned vehicles, remotely driven or
controlled through artificial intelligence, are instrumental to foster space
exploration. One of the most essential tasks of a rover is terrain traversing
which requires the need of efficient suspension systems. This communication
presents a suspension system giving degrees of freedom to every wheel with the
help of linear actuators connected through bell crank levers. The actuation of
linear actuators directly varies the height of every wheel from the chassis
hence offering articulation to the rover. A control system is developed
offering an algorithm for its autonomous actuation. This system proves
instrumental for leveling of the chassis where any kind of slope, roll or
pitch, may impute abstaining of payloads from efficient working. This was tried
and tested successfully as a part of the rover developed by Team RUDRA from SRM
University, INDIA (first Team from Asia and finishing at the fifth position) at
University Rover Challenge 2013, held at UTAH, USA in May-June.
