4WD Arduino Controlled car - Problem with motor shield

Click For Summary
The user is building a 4WD Arduino-controlled car but is facing a limitation with their Arduino UNO motor shield R3, which can only control two motors. They seek advice on whether it's possible to use this shield for all four motors or if they need to purchase a new one. A suggested solution involves connecting the two left-side motors in parallel to one control channel and the two right-side motors to another. This approach may work if the car uses a skid-steer mechanism. The discussion highlights the need for potential modifications or additional components to achieve full control over the vehicle.

I've been working with what will be a small Arduino 4WD controlled car, however now I've found a problem.
The motor shield I used is an Arduino UNO motor shield R3, v3, which means that it can only control 2 motors, howerver I'll be using 4. Is there any way to use this same shild but apply all 4 motors or will I have to buy a new shield?
If so, any recommendations?
Thanks

Welcome to PF.

It depends on how the steering is done. If it is skid-steer, you might connect the two motors on the LHS in parallel and run them from one control channel. Connect the two on the RHS in the same way to the other channel.
 

Thread 'What mathematics software should engineering students use?'

What mathematics software should engineering students use? Is it correct that much of the engineering industry relies on MATLAB, making it the tool many graduates will encounter in professional settings? How does SageMath compare? It is a free package that supports both numerical and symbolic computation and can be installed on various platforms. Could it become more widely used because it is freely available? I am an academic who has taught engineering mathematics, and taught the...
