Re: Best Sensor for Unlimited Rotation Swerve

4/(1/400)*18*.0254/(.004/.000024)*3.28 = 14.4
Correct me if I'm wrong however we expected to mount this approximately 5.5 inches or 0.139 meters above the ground since that is the clearance of the our swerve modules.

- Also we have purchased an additional M12 lens to swap out which is adjustable in focal length from 2.8 to 16 mm

Assuming the minimum of 2.8mm I was thinking that

4/(1/400)*0.139/(0.0028/0.000024) = 1.9 m/s or 6.2 ft/s

Now that may not be the max speed the robot is capable of but we feel that it is an acceptable speed for accurate autonomous navigation which is what we are trying first. So it really doesn't fit into the whole theme of being an all purpose swerve sensor, but the technology used is very intriguing and our key problem with swerve is more of navigating in autonomous.
