Hi,all
There is a big problem i faced while constructing a Robot , me and my friends will participate in a competition with it.
The problem is that our robot walks with two wheels actuated with two DC motor in the Back,
while there is a free wheel in the front which can rotate freely if the back wheels force it.
The robot walks as ordinary.To go straight , back wheels work forward , totally reverse for backward. One wheel forward and the other backward for going left or right.
The problem is that when the robot wants to go forward or backward for a long distance , it cannot walk straight ahead, because the back motors are of different speeds.
They are typical motors (Toshiba motors , 180 RPM , 24VDC) , but the motors are used so they have bit different speeds.This makes going forward or backward in a straight manner almost impossible.
One side of the robot is faster than the other side.
We suggested a solution using line tracking sensor and already made it.
It worked well, but it corrupts very quickly and doesn`t make a very good performance.
I feel there are for sure other solutions.
So if any one can help me , please do.
How can the robot walk is a straight line having two motors with different speeds in the back?
