Motorised Wheelchair - Project Choices

[JonnyAlpha]

Hi;

I have managed to get hold of a fully operational motorised wheel chair, 2 x Independent Geared Motors, Control Panel, 2 x 12v Batteries and Battery Charger.

I now need to think of which project to use it for, I'll be building it in conjunction with my Schools coding and robotics club. I have always wanted to build a Dalek but could have some other ideas, such as Wall-e, Davros or a custom bot.
The Dalek would be easiest as it would use the existing wheels, Wall-e needs tracks and Davros would be too scary.

I asked the kids "who watches Dr Who" - answer - No one!! Maybe a Dalek would not be so popular but I think any large scale robot would be a hit.

Anyone got any other suggestions.

My anticipation is that it would have a manual control for moving it around and autonomous mode. I have been experimenting with this on a smaller scale using my RPi, WebIOPi and Arduino Nano and an i2c interface. This has proven a little clunky so this robot will probably have its motors driven using the Pi to control the existing Motor / Speed controller?

Maybe you should ed-u-cate them

We have a little cardboard TARDIS that sits on top of our christmas tree each year and has a light on the top that is pulsed by a Pi at random intervals. Also our doorbell is linked to another Pi that makes the sound of the TARDIS
