In the DARPA grand challenge, full-size, un-manned vehicles were tasked with following a route in the desert described by GPS coordinates (http://en.wikipedia.org/wiki/DARPA_Grand_Challenge). I thought it would be interesting to do the same thing, but with a radio-controlled car (in my case, a Traxxas Slash 5803). To make the car drive autonomously, the radio controller would be replaced with a programmable logic controller.
To make the car autonomous, I needed to have the PLC:
- Control steering and acceleration (http://jeffsinventions.com/?p=784)
- Include a kill switch (http://jeffsinventions.com/?p=841)
- Detect and avoid obstacles (with an ultrasonic sensor: http://jeffsinventions.com/?p=881 and with computer vision: http://jeffsinventions.com/?p=1202)
- Navigate to locations (http://jeffsinventions.com/?p=922)
