EXTRATERRESTRIAL EXPLORATION REQUIRES INNOVATION IN LOCOMOTION METHODS AND THE ABILITY TO MANEUVER ROUGH TERRAIN. CURRENT ROVER TRAJECTORIES ON MARS MUST BE CAREFULLY PLANNED TO MINIMIZE RISK REDUCING THE SET OF REACHABLE LOCATIONS AND SLOWING DOWN PROGRESS. SOLUTIONS SUCH AS ACTIVE SUSPENSION LEGGED ROBOTS AND TENSEGRITIES ARE PROMISING BUT INTRODUCE VARYING LEVELS OF MECHANICAL AND COMPUTATIONAL COMPLEXITY AND THUS RISK. MEANWHILE FLYWHEELS ARE CURRENTLY THE STANDARD FOR PRECISION ATTITUDE CONTROL. CONSEQUENTLY A SIMPLE QUICKLY-REALIZABLE SOLUTION FOR ADDITIONAL TERRAIN FLEXIBILITY IS TO USE THE GYRODYNAMIC PROPERTIES OF A FLYWHEEL TO REDISTRIBUTE A ROVER S WEIGHT OVER ITS WHEELS IN ORDER TO MAXIMIZE TRACTION FORCES AND STABILITY. THE FLYWHEEL CAN ALSO SERVE AS A RECHARGEABLE ENERGY SOURCE TO OFFLOAD BATTERY CAPACITY AND CYCLING REQUIREMENTS. THUS THIS PROPOSAL SEEKS TO DEVELOP BOTH TA 4.2.5 SURFACE MOBILITY AND TA 3.2.2 FLYWHEEL ENERGY STORAGE.
