FPGA remote controlled vehicle

A large project with more depth in terms of analog circuits and digital logic. The assignment was part of an electronics course and was given in the first few weeks of the semester. Enduring an entire semester i.e. 4 months.

Outline

The following specifications was given and everything outside of this was up to us:

• Remote controlled unit with two wheels, one DC-motor each
• Control input and vehicle response process in Xilinx FPGA using VHDL
• Direction of the unit determined by the speed of the motors
• Front wheel spinning free
• Speed and direction is adjusted by two potentiometers on the remote
• Switch to indicate Start/stop
• Communication wireless over Xbee modules
• Unit built by discrete components and the logic on a development board
• Speed adjusted by a PWM-signal for efficiency
