Lego mini 4 wheel drive with BOE board

This is the first H bridge program I have made using sensors. So far so good. It is not fast, but has alot of torque. This is the geared up version that works. The Lego motors are rated at 9V, but using 7.2V through a H bridge. Similar modified Whisker program as the Lego Boe Bot just listed.


Here is a short video

Nice bots, crazyrabbit, and you're cranking them out two at a time! Fabulous work, we're ready to see a figure 8 any time you are.

Looks like this guy has also been into Lego for a while... https://www.youtube.com/watch?v=4wEJ1Tk4K30

That is quite awesome. It's also a sign that someone has way too much time on their hands!!!!

No Erco,really just started the Lego thing this last summer. Thought I could get some Lego converts to the BS2 at the Detroit Maker Faire last July. Just starting on the Lego NXT controller. So easy to program, but limited. The best thing is the bluetooth programming and remote control. Still take the BS2. Lots of I / O.

Good for you with following through with using Lego robots and Parallax gear.

My son and I have an NXT set and we've built a few robots with it. But found the NXT brick is limiting after your do a few projects. It also gets really expensive to interface custom sensors to it.
