Wireless network or Internet controlled vehicle
This project will take a standard off-the-shelf radio controlled car and replace the standard radio receiver with a Raspberry Pi fitted with a PiXi board. The Raspberry Pi will be fitted with a WiFi dongle to allow the vehicle to be controlled over the Ethernet or Internet by applications running on (say) a smart phone or any networked computer.
The PiXi will provide the PWM control for the direction & speed control. Spare PWM controllers on the PiXi may be later used to control the orientation of a camera fitted to the vehicle.
The open-collector outputs may later be used to drive an array of lights, LEDs, a sounder.
The PiXi allows an array of sensors including the on-board accelerometers & external sensors such as range-sensors, PIR detectors, GPS to be added later on to offer a further level of interaction with the environment without having to worry about over-allocating the GPIO on the Raspberry Pi.
The PiXi will have the optional 5v regulator fitted so that the PiXi & Raspberry Pi can be powered from the vehicles 7.2v or 8.4v battery pack.
