I have been pondering some more on this:
As the robot is going to be doing a set route round the house is there and chance of just using ultra sonic distance sensors to navigate round (rather than having to have lines drawn round the house for it to follow)
Over much coffee no doubt
I really like this project and hope you keep at it. If only we could make the robot climb stairs I'd think the same project could be a must-have.
I am wondering if an optical mouse would be a easy way of tracking actual movement?this combined with a ultrasonic sensorbtw-all the floors are wooden
