I have been working away at my Lego Pibot recently and now have something to show for it.
I rebuilt the entire thing making it more efficient in turning, it uses a towering design and is more modular. It has 4 levels with batteries, pi, breadboard and camera.
It also has support for an additional attachment on the front, so far I have used that to attach a lift-able pen on the front to draw over paper (turtle style). Finally I have added space for a breadboard and also added the extra motor for rotating the webcam.
All the electronics are the same as the first Lego Pibot with the exception of the additional motor and the breadboard for prototyping. i have also added a cheap ultrasonic sensor off eBay to it but am having issues with it right now.
What isn’t shown in the video is the wiimote support I have added. I have written an additional script for controlling the robot with Bluetooth using a wiimote.
When it is finished I will post the source code, as normal, it is in python.
Also new is the addition of scratch controlling. The robot can be really easily controlled by scratch GPIO making it really simple to write control programs.
As normal, if you have any questions on this, post a comment below or on the video.
