Hello All, First project, not sure if this has been done already - perhaps not like this exactly.
I've spent many years working in software so when I have a chance to play with hardware and linking in what I already know - i get exited - Im hoping to learn a little about robotics and have a bit of fun.
The plan is to make a simple module for an RC Car consisting of a raspberry Pi and a WiFi dongle.
From there you will be able to log onto it as a WiFi access point, launch a web browser and then use the gyro (if your phone supports it) or push buttons to control the car. Eventually to integrate a camera so you can drive the car from the screen. I may also have a go at a bluetooth version and 3G dongle version and perhaps a Wii controller. I want it to be simple and responsive and I think using a website to control the car should be simple and universal.
In this first video, after 30 minutes or plugging the SD Card in I have the servo and speed controller being controlled from the command line.
Im using the daughter board to make controlling the servos easy. Apparently use PWM or some timing to control the servos accurately is hard or impossible with out something in-between - i have seen people using arduinos and other boards - this wants to be simple. Im also not a hardware person so I brought this board in so I can concentrate on the software.
Big thanks to Mikael at Chroma electronics for soldering me up one of his awesome and simple servo boards: http://electronics.chroma.se/rpisb.php
Next update soon
p.s. anyone know how to embed a youtube vid in a post ?
