Red Wedge Down

Whilst reviewing Red Wedge with a view to letting the Young Roboteers a go driving a small combat robot, I realised that one of the wheels was seized. After stripping the gearbox, I found that many of the gears had broken teeth which were jamming the gearbox.

So I need a replacement if Red wedge is to fight again. This is an old motor from an cheep drill I think it was B&Q we got them from. This was before the moder LiPo batter drills.

K9 - Is there anybody home?

ROS on my pi

It was fun to build a K9, but there is something missing to my canine companion. That is intelligence!

With this in mind I'm investigating the Robot Operating System or ROS for short.

It has been painful getting it onto the Raspberry pi, as the instructions are not quite as complete as you would like and my knowledge of the raspberry pi is a little sketchy. Consequently it has taken about a week of the Christmas break to get it installed.

However, it is now on the pi (and backed up) and I've started on the actual ROS tutorials :)

So far I've got as far as driving around a simulated turtle, as above
