Question about motors. My team is having to move our lift motors to the inside which would affect tray angle. The reason we have to move them inside is because the sizing tool does not easily slide over them when we sized it. My question is : is it legal to file the plastic nubs that attach the motor to a C-Channel down a millimeter? or would this violate
R21 No modifications to electronic components are allowed. Motors (including the internal PTC or
Smart Motor firmware), microcontrollers (including V5 Robot Brain firmware), extension cords, sensors,
controllers, battery packs, reservoirs, solenoids, pneumatic cylinders, and any other electrical component or pneumatics component of the VEX EDR platform may NOT be altered from their original state in
a. 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 undesired results.
b. Teams are advised to use the latest official VEXos firmware updates, found at www.vexedr.com.
Custom firmware modifications are not permitted.
c. Teams may change or replace the gears in the “2-Wire 393” or “2-Wire 269” motors with the
corresponding official VEX Replacement Gears
d. Teams may change or replace the gear cartridge in the V5 Smart Motor with other official
replacement gear cartridges
R22> Most modifications and repairs to non-electrical components are allowed. Physical modifications such as bending or cutting are permitted and may be done to legal VEX Robotics Competition
metal structure or plastic components.
a. Physical modifications to electrical components such as a legal microcontroller or radio is
prohibited unless otherwise explicitly permitted, per .
b. Internal or external mechanical repairs of VEX Limit and Bumper switches are permitted. Modifying the metal arm on the Limit Switch is permitted. Using components from these devices in
other applications is prohibited.
c. Metallurgical modifications that change fundamental material properties, such as heat treating,
are not permitted.
d. Teams may cut pneumatic tubing to a desired length.
e. Teams are permitted to fuse/melt the end of the 1/8” nylon rope to prevent fraying.
f. Welding, soldering, brazing, gluing, or attaching in any way that is not provided within the VEX
EDR platform is NOT permitted.
g. Mechanical fasteners may be secured using Loctite or a similar thread-locking product. This may
ONLY be used for securing hardware, such as screws and nuts.
allows modification of non electronics.
So as long as we dont hit electronics we would be fine right?
