Here’s a tip from the experienced teams: remove all the screws from your robot’s motors, and instead hold it all together with a large zip tie. This method allows super-fast swapping out of motors and gears, and allows quick access to cool down your motors in between matches.
VEX Worlds and certain local tournaments include a “PTC test” on robot motors to ensure they have not been illegally modified. Here’s the details.
Today I want to relay some more useful information from the awesome jpearman on the VEX Forum regarding motor ports 1 & 10 that will affect the way you’ll want to allocate ports in your robot design. I seem to be writing encyclopedic posts lately, so here’s today’s table of contents: Inside the cortex: 2 CPUs […]
Slew rate refers to a programming method to slowly increase the power to a VEX motor, in measured steps over a set period of time, to reduce the possibility of current spikes which can trip the motor’s internal circuit breaker.
My final post for this Thanksgiving weekend. I think that being able to identify motor overload is one of the more useful things that a coach or mentor can do, as it often points to a design flaw — and the sooner those can be identified, the better!
In response to a Facebook request, I’ve made a deeper dive into how motors work. Here is an explanation of voltage, current, torque, and speed in layman’s terms.
Don’t be afraid to open up your motors to check out the gears when things don’t sound right. Here’s a primer on what you’ll find when you open up a VEX motor and how to figure out if there’s something wrong.
Spread out your motors across motor ports 1 through 10 for best performance.
Why do some motor ports on the cortex have 2-prong plugs and some have 3-prong plugs? What are those little plastic doo-dads that connect the motor to the cortex? How do they work? When do I need them? Read on for a short primer on motor controllers!
