Moving along the edge

(1/1)

teekay:
Hello,

Does anyone have an idea to make a robot move along an edge (of a table etc.) without using any image processing technique..?

snow:
Two IR sensors: [ROBOT]--[SENSOR1]--[SENSOR2].

If SENSOR1 is on AND SENSOR2 is off you are going ok.
If both on you must turn toward the edge.
If both off you must turn away from the edge.

If SENSOR1 is off AND SENSOR2 is on your robot has already fallen down and broken the sensor holder :)

Admin:
As snow said, you just need a sensor that can detect where the table edge is.

Try this:

and look up line following robots (an edge is also a line)
