In all seriousness, i really like the design. very simple yet effective with the vex single reduction gearbox.
How fast does it travel? From the picture, I cant tell if it is a 6 or 8 in wheel. If it is 6in, it would be at least 17ft/s and if it is 8, that would be 23ft/s
, both of which are too fast imo for a single speed robot.
I have always stayed away from omni wheels because of their lower traction. Are you guys worried about being pushed around? of course, with this type of agility, you can just move around people, but at 17ft/s your acceleration wont be too high.
