A small project transforming a cheap RC car into a robot rover!

Building a Rover project day 2 – PWM on BeagleBone

When I bought the BeagleBone it didn’t have PWM support. It was disabled for some reason by default. Luckily in the latest kernel they put it back.

The minimal kernel for PWM is: Angstrom v2012.03-core – Kernel 3.2.5+ .

The one I downloaded:
http://www.angstrom-distribution.org/demo/beaglebone/Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.05-beaglebone-2012.06.18.img.xz
Which has a 3.2.18 version kernel.

This is optional, but you can update to the newest version.
The first step is to update the BeagleBone. You will need the BeagleBone to be online. Then here are the necessary commands:

opkg update
opkg upgrade

Building a Rover project day 1

Continuing yesterday’s work Árpi moved out to do some shopping for heat-sensors and a wifi-stick for the BeagleBone.
I did some the code for the Arduino which is basically a command interpreter based on the code of the OpenROV project.

We successfully mounted the servo motor that does the steering and experimented with drilling an extra hole into one of those metal builder parts to shorten the steering axis – no good yet.

Building a Rover project day 0

It’s summer time! Best way to spend it, to hide from the sun inside in your room and create rover. Our first rover will be the Scarabeus! It will be created from an RC car (which we bougth from local supermarket). We tried it without customizing anything of it, here you can see the video:
