Looking to build a 4 wheel differential drive chassis that needs to work well on multiple surfaces like carpet and wood and especially transistioning between the two.
Using the following (the ones from Pololu):
100:1 Micro Metal Gearmotors
42x19mm Idler Wheels
driven by the Dual MC33926 motor driver shield and Arduino Leonardo
Question 1 is - Can I hook 4 motors of the above (2 per side) up to the MC33926? The specs say the 2 motors will not exceed the draw but thought I’d ask.
Question 2 is - Opinions on driving all 4 wheels (2 channels of drive both L and both R) for best differential turning response - or just stick with the 2 rears?
Can’t seen to find any discussion on these 2 topics anywhere…
Thanks in advance for any suggestions or points to discussion.
