OK first


what do you mean by path follower? what is the path?



three wheel bot is no problem.

I would recommend using HDPE for the material, buy it from McMaster

also what microcontroller will you be using? and what is your budget

as I said before McMaster.com

Also I would first build the robot and then program it.  :P


Also, what is the path that it is following???

Do some research before you ask questions like if three wheeled robots are ok.
The forum is FILLED with info on three wheeled robots...

search GOOGLE!!!!


here is a robot that admin made :

I am working on a robot with two wheels and two casters, basically just for balance and to make room for my line sensors

Do you know how to track a line already?

If you want something cheaper than an omniwheel, you could also go with a ball caster.
