I was looking on YouTube and I found team 44 old wheels, I wondered if they are legal or not. It looks that they are a lot thinner than the VEX Macanum Wheels, something that I know our team needs this season, thanks in advance.
Also what wheels do you believe to be the best this season
As long as they’re 100% VEX parts and don’t violate rule <R15> there’s no problem in using them.
<R15> Parts may NOT be modified as follows:
a. Motors (including the internal PTC), extension cords, sensors, controllers, battery packs,
reservoirs, solenoids, pistons and any other electrical component or pneumatics component of
the VEX Robotics Design System may NOT be altered from their original state in ANY way.
• Internal or external mechanical repairs of VEX Limit and Bumper switches are permitted
o Using components from these devices in other applications is prohibited
• External wires on VEX electrical components may be repaired by soldering, using
twist/crimp connectors, electrical tape or shrink tubing such that the original functionality /
length is not modified in any way. Wire used in repairs must be identical to VEX wire.
Teams may make these repairs at their own risk; incorrect wiring may have
• Teams may change or replace the gears in the “2-Wire 393” or “2-Wire 269” motors, with
the corresponding official VEX Replacement Gears
• Teams may cut pneumatic tubing to a desired length
b. Welding, soldering, brazing, gluing, or attaching in any way that is not provided within the VEX
Robotics Design System will NOT be allowed.
• Mechanical fasteners may be secured using Loctite or a similar thread-locking product.
o This may be used for securing hardware ONLY.
• Teams are permitted to fuse/melt the end of the 1/8” nylon rope to prevent fraying
• The gluing permitted by <R7h> is an exception to this rule.
However, you’re probably better off using the normal VEX mec wheels. These were built before the VEX ones were introduced, but now it is not necessary to build your own.
Thanks, I know the VEX ones are probably more efficient it was just these seemed thinner, I don’t think our school would allow it anyway. But thanks for clearing it up.
