Return of the OmegaBot!
-
A couple of years ago I posted my first version of an Omega2-Powered Robot which was a lot of fun and well received.
However, it had a few issues:
- The robot base was a bit tippy
- The motor driver circuit was a little hokey, and couldn't handle much current
- Forward motion only
So I've made a new one, using the same basic architecture (Omega2, PWM Expansion, python) with a few improvements:
- Replaced the base with one from a "Thunder Tumbler" RC Car
- Used a TB6612FNG as the motor driver, for forward/reverse and higher current (Sparkfun Breakout)
- Reworked the python code significantly
Here it is!
It works really well! Not visible are the 4x AA batteries in the base to power the motor.
The code and datasheets are up on GitHub if anyone's interested: https://github.com/LeifBloomquist/OmegaBot/
I'm also working on a way to control it with the LEAP Motion (hand gestures), will post a video once that's working.

@Leif-Bloomquist That's so cool, thanks for posting! Maybe voice control next ?

Very cool!

@Leif-Bloomquist Please let us know the type (the chemistry) of your "not visible 4x AA" batteries (primary/single-use or secondary/rechargeable) and how they are connected (parallel, serial or mixed). Thank you.

@György-Farkas In series, using single-use for now since that's what I have on hand. But rechargeables would probably work.
The battery holder is just one of these, though it came with the R/C car and the cover is a slightly different shape.

Cool project!
