Lego Pibot revision 0.2

 

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.

We WON!

 

On Wednesday the 20th of April the Dalriada school robotics team traveled to Cambridge to compete in the PA Consulting Raspberry Pi competition. Our team brought with us a prototype of our revolutionary new product, the Raspberry Pi Powered Internet Connected Pill Dispenser. This device uses a raspberry pi, connected to the internet to dispense pills at predesignated times that have been defined on a custom made website of ours.

All this for under £50!

When we arrived we were met by some helpful PA Consulting staff that had been assigned as our representatives for the day. We went up through a maze of halls to the event room. A massive room with banners everywhere and a lot of raspberries. We went over to our area and set up

Our whole design is a bit of a mess but we left it out of its box so people could have a look and see how it worked

We have plenty of cables. Spot the raspberry pi in there.

After setting up I was immediately thrown in the deep in with an interview as no one else in the team wanted to do it. You can see a shortened version in the video above.

We then got shown around PA Consulting’s building and got to see some cool 3d printers, a machine for making kitchen roll (Way more exciting that it sounds) and a number of other activities planned for us. We then had to demo our design to a number of judges, this went ok but could have gone a lot better after a jammed the machine up by pulling out the wrong bit 🙂

After this the judges continued round the rest of the teams and members of the press and PA Consulting clients came and we presented our product to them, these seemed to go a lot better and we ended up with a number of impressed people including a lot of “My mother/father would greatly appreciate one of these”.

After a tantalizing wait, the judges announced the winners including us and we each walked away with a raspberry pi (My 4th raspberry pi) and a PIbow. The school got a golden envelope with £1000 in it (which we plan to spend on a classroom of raspberry pis) and an custom engraved Pibow case.

 

We had a stunning day and would especially like to thank PA Consulting for putting on this event
