Abstract :

The Rocker-Bogie Mobility System Was Designed To Be Used At Slow Speeds. It Is Capable Of Overcoming Obstacles That Are On The Order Of Side Of A Wheel. However, When Surmounting A Sizeable Obstacle, The Vehicles Motion Effectively Stops While The Front Wheel Climbs The Obstacle. NASAs Currently Favored Design, The Rocker - Bogie, Uses A Two Wheeled Rocker Arm On A Passive Pivot Attached To A Main Bogie That Is Connected Differentially To The Main Bogie On The Other Side. This Paper Describes A Method Of Driving A Rocker - Bogie Vehicle So That It Can Effectively Step Over Most Obstacles Rather Than Impacting And Climbing Over Them. Most Of The Benefits Of This Method Can Be Achieved Without Any Mechanical Modification To Existing Designs Only A Change In Control Strategy. Some Mechanical Changes Are Suggested To Gather Maximum Benefit And To Greatly Increase The Effective Operational Speed Of Future Rovers. The Rover Has Been Completely Made From PVC To Increase Its Capability To Withstand Shocks, Vibrations And Mechanical Failures Caused By The Harsh Environment Where It Is Operated On. Using CAD Software, The Design Of The Rover Has Been Fine-tuned And By Experimenting With Prototypes And Models Of The Rover In The Experimental Setup Of The Live Test. Key Words: Bogie, Mars Rover, Mobility System, NASA, Rocker-Bogie Mechanism, Rocker, PVC Pipes, Rough Terrain
