Mechanical Engineering Senior Theses

The versatility of current rovers and exploratory vehicles is limited by a single drive system. The Variable Drive Vehicle (VDV) employs a actuated systemcapable of switching between wheeled and tracked drive modes. This allows the vehicle to travel quickly and efficiently over smooth terrain and to traverse more arduous terrain by switching between these two systems. The small scale prototype built over the course of this project is equipped with two modular wheel driven track units to demonstrate the viability of the system. Electric linear actuators and servo motors allow for simple control and a smooth transition between each drive …
