electronic enthusiasts!
I am trying to build a balancing robot with two wheels, using the polulu gear motor as mentioned above. In order to have a strong motor driver,the monster moto shield is used in this project. Here is the components and datasheets which is used.
Components
Li-poly RC Battery 2800mah 11.1V 35C.
Arduino saint smart
2x Pololu 12V, 29:1 Gear Motor w/Encoder
Monster moto shield
Now, back to the issue.. Well, the first problem I encountered was my motor driver. It keeps getting hot after a while, whenever I use it ( I run 2 motors through 1 driver). And the most frustrating part is that the motors can stop for a while, and then restart again ( suspect a hardware reset here). Is there any way this can be solved?, I have checked the datasheet for the monster moto driver but can't understand whether the components are already on the PCB boad or I manually have to add new components like resistors, capacitors and etc. Would be glad if you guys directed me on this issue.
Secondly, The other problem I have is that the motors are going fast CW and slow CCW whenever I reverse direction. I have also seen other ppl getting the same problem as I do and wonder why this happen. Could it be that the cables are to small for the current flow ?
Should I add external components ? Then which components should I use in order to subdue this problem?
Here are some pictures in order to clarify the problem. Mostly using cables to connect inputs and etc. I would be glad if you wonder something and want me to post more information.
