I created H-Drive but the middle wheel will spin. but wont make the robot strafe. For some reason .mp4 isnt allowed so i cant post a video of the issue

IQ fields are hard plastic, not squishy foam like VRC.

Still though it clearly does not have enough traction. This can be remedied by moving the wheel down. If moving it down more off centers the base, the robot is likely too heavy

[image] holbrook: Well if the wheel spins but the robot doesn’t move as a result, then there muse be some difference in the height of the middle wheel compared to the other wheels. Otherwise the robot would move when the wheel spins. just a technicality, but i believe a better explanation wou…

[image] Ethan5956F: it’s not the height that matters, it’s the how much traction the individual wheel has, compared to it’s acceleration; just because something has more normal force doesn’t mean it necessarily has more traction, cuz traction in newtonian is essentially Ff=μN. Well yeah that’…

Just a few things to note that may or may not be useful: -Yes, the field is hard plastic but if your field is on carpet (even the hard kind in schools) it can have a significant impact. We built a kind of lattice out of wood which helped a ton -the overall weight of your robot does matter too but …

Just don’t use WD40 though, because it is illegal in IQ. [image] WD40 in IQ General VEX IQ Competition Discussion The relevant rule here is R7: <R7> VEX IQ product line. Robots may be built ONLY from Official Robot Components from the VEX IQ product line, unless otherwis…

i dont know how to do that- i have never used google drives do macs even have google drive?

H-Drive (Omni Locus).mp4 Google Drive file. and H-Drive (Traction_Wheel Locus).jpg.mp4 Google Drive file.

one has omni wheel in the centre and the other had tration wheel in the centre. Note- the four drivetrain wheels are standard traction wheels.
