Inverse kinematics:

Code:


S1 = STR + (L/2)*Omega
S2 = FWD + (W/2)*Omega
S3 = STR - (L/2)*Omega
S4 = FWD - (W/2)*Omega

... then normalize if any wheel exceeds max speed
L = wheelbase, ft
W = trackwidth, ft

FWD = forward, fps
STR = strafe right, fps
Omega = clockwise rotation rate around center, rad/sec

S1 front right wheel linear speed, fps
S2 front left wheel linear speed, fps
S3 rear left wheel linear speed, fps
S4 rear right wheel linear speed, fps
