position with compass and accelerometer

I'm doing a work to university.
I need to study diferents techniques of robot position.

Sometimes you need to know what position a servo is currently in. Two examples are: 1. The robot has lots of legs and the power has just been turned on. Without … Read more

Robot position with quadrature encoder

I'm building a robot for environment mapping. It's a simple "start here"-class robot: 2 wheels, 2 dc motors and a range sensor mounted on a servo. I plan to hook it up with my PC 1st by USB and later on by wireless somehow.

I want it to drive around and send the range sensor readings to the PC which in turn will be building a map of the environment. The hard part will be knowing the robot's position relative to it's earlier position(s). I know this would be easy with a GPS or an accelerometer, however I wish to find a more lowtech/DIY solution, so here is my idea:

Use an Arduino GPS Shield to Fix position,altitutude,time,date........

Does your Robot need to fix its absolute Position - Speed - Heading - Time - Date & Altitude.

Here is a Guide to explain the Process.

Isn't that just a pot? You are forgiven for thinking you are looking at a photo of a potentiometer AKA variable resistor. That's what this looks like. However, if … Read more
