Welcome to EZ Robot we look forward to seeing your creativity.
I need to make a prototype of a line following robit that can carry parts in a warehouse.
This will be a proof of concept vehicle for now.
Just purchased Thumper 4WD Chassis With Gripper. Hooked up using video for 2.5 Amp Motor Controller. Seems to be connected but I guess using the power pack that came with kit is too small to move it at all. I hear the connection to moter and it moves back and forth a little.
What size battery is everyone using?
Also can you separate the power from the controller ?
I would like to use 2 different power sources if possible, one for controller and one for motors.
Thanks for the help.
