This is a microcontroller-based RF-controlled car equipped with a wireless camera. I designed this robot in 2016 for an Army Major to assist with a mission. The RF system has a range of approximately 300 meters. It utilizes a PIC16F73 microcontroller, motor drivers, DC gear motors, an RF module, and a lead-acid battery.
