This is a nice new product. It has better H-bridge and a display.
Could you please publish the schematics?
Looks very much like B-168 with dislpay and buttons. Too bad you did not make it earlier - I had to re-create it with separate components in my line-tracer:
Thanks for noticing; it is too bad we didn’t have it earlier since it’s been on our to-do list for a long time. The schematic should be up later today, but it’s very similar to the Orangutan LV-168. The only differences are the different H-bridge, a step-down regulator instead of a step-up unit, and battery voltage measuring on ADC6 instead of the temperature sensor.
That robot looks nice. How fast does it go? Is there an interesting reason you didn’t use our QTR-8RC reflectance sensor array?
Currently it only makes about 20 in/second, but its motors can run twice as fast. I am now struggling with PID tuning, so it may take me a while to realize its full potential.

I used 3Pi for design inspiration and for borrowing code. Its difference (other than looks) is no booster 6 NiMH supply, Maxon 13017 motors and 6 sensors. Hope you do not mind my massive borrowing since my bot has quite a few Pololu components (roller, lcd, wheels and B-168).
QTR8-RC would actually work OK, but I wanted to have a different layout. The sensors schematics is the same.
Thank you for posting your videos! The Orangutan SV-168 schematic is now available under the product page’s resources tab.
