This thesis describes the development of a small , inexpensive , controllable mobile two -wheeled robot . It also describes the development of a software interface which allows several open - and closed -loop control methods to be easily implemented . The developed hardware and software modules provide for an open and modular system for research purposes . This is demonstrated through the Bluetooth wireless control of the robot using LabVIEW based software modules . The open -loop control inputs implemented are sliders in a LabVIEW GUI , joystick , and voice commands . The closed -loop control methods included a PD control algorithm that guides the robot to go directly to a user defined point , and a path planning control algorithm that guides the robot to follow a path and reach the user defined goal in the correct orientation . The closed -loop control methods use an external camera for vision based position feedback . All the control methods introduced were successfully tested experimentally . |
