OK This is my first time in the robotics section, so be gentle with me
:?
I want to build a robot with a simple skid steering system which responds to simple commands such as "go forward 1 metre" "turn right 45 degrees". Its position in a room will be mapped by a computer which is controling the robot.
I am quite confident with the microelectronics side of things.
My Robot will need to move around in a room collecting data for up to 24 hours.
My question is:
Will normal servo type motors (like **broken link removed**) have sufficient precision for what I need?
Or will I have to use stepper motors?
I can imagine that lack of precision will be cause compound error. (ie if my command "go forward 1metre" only results in the robot going forward 99cm then after a "go forward 10metres" command it will be out by 10cm
Is there any other common ways of getting around this?
Thanks
John
