Single transistor balancing robot

[vjnghfg]

can you upload shematics?

single transistor?

Yup, single transistor...in the linear domain. I'm using a little infrared range finder as a sensor (to be fair, that's more that one transistor!) and using the output signal to modulate the MOSFET. What's shown is a finely tuned proportional only system that is only capable of short term stability (like pretty much all P only balancing systems).

Although this is a very simple robot, it can be a challenge to get it to work.

do you have any schematics?

looool :D
