How can I best attach The BrickPi battery pack, and pivot pi and other things to Lego's?


Hello, I am building a driving robot and am having extreme difficulty getting the pivotpi, pivotpi battery pack, and BrickPi battery onto Lego’s. Since they have no direct way to connect, it is hard. I’m curious how do you guys do it?

That’s my setup.

Thanks! :slight_smile:


Hey @graykevinb, We haven’t thought about this much before, but it’s a good question. The PivotPi is really meant to be attached to the Raspberry Pi . . . after that, we hadn’t contemplated what to do. Any suggestions?


I have had great sucess with just using a bit rubber band and doubling it over. I used this when using the orginial 8xAA cell battery pack and also my new LiIon battery pack see attached pic of my new blue coloured battery


I did find that I had to extend my original battery pack lead as it was a bit short and I also changed the plug to a elbow plug where it plugs into the BrickPi to make it more low profile and easier it fit on small compact robot


Nice! A case for the battery pack would be nice for attaching directly to legos.


Do you have access to a 3D printer? As most robot builders just design and print any simple mounting type harward


Kinda. Just not a computer capable of handling cad. The whole point of the lego system is you don’t need one.
