problems of irobot create?
« on: November 28, 2010, 07:52:07 AM »
I had to open-up my Create to clean the Wheel Encoder because it would occasionally take-off in a hard turn (one wheel encoder wasn't seeing the ticks so it would make the wheel turn faster to "catch-up" to the other wheel).

so, when i make irobot drive direct it doesn't.

if i want to solve this problem with programming how?

It's not possible to detect an encoder failing unless you have other sensors as well.

This is a common problem for the create, if you google it you will find at lot of info on the subject. The only solution is to take it apart and clean it.

Many years ago I had a problem with a robot that somehow attracted a *lot* of dust onto it's IR sensors. It'd run for ~10 minutes, until the dust got too bad to work.

I had theories that static charge was responsible, but never managed to solve it.

My ghetto solution was to attach a high powered fan to it to blow dust away. See below image, its that orange thing in front.

Point being, maybe you can try various solutions to keep dust from getting into the encoder area . . .
