Just help! (basics)

I have a VEX PIC Controller VEX-276-2170, I want to get the right wires to connect motors to it. On just about every site I see, there are two-wire connectors, and when I look in the motor ports on my controller, it looks to need a 3-wire connector. Please help.

PIC controllers are three wires, The older style motors were also three wires so it worked. The newer VEX Cortex motors were 2 wire and needed to have a motor controller on them. (Motor controller 29). If you have older PWM motors they will plug in, the newer motors will need the motor controllers)

Smaller PWM motors from hobby places will work. You’ll need a male to male header to make it work.

On the PIC the ground / black wire is the outside of the pin set.

Happy to help, just about 9 or so left that remember how to use them.

I’m going to assume you have access to the free RobotC for those devices.

Good lick, welcome,to the forum, post back your creations.

@Foster, I still have your old baby firefighting robot:

vex-0.5-firefighting-robot

Do you want it back?

Or, if you still have programming tools and the code, I could try to revive it.

Wow, I haven’t seen that robot in YEARS, I’m thinking 2012 or 2013. Where did you find it?

It used a fan to blow out the fire. The red can is a film canister with an ir sensor to find the flame, the canisters blocked the ambient light.

Encoders to keep it going straight, the sonars let you know where the door openings and walls were. They really taxed the power of the PIC.

If you want to fool,with it, there is an archived version of Robot C on the Vex site. You have the program cable. Give it a whirl.

I have vague recollections that it entered a room, spun and if it saw the fire it would kick on the fan and spin side to side to blow the flame out. There was a rule change one year that you had to be within 18" of the fire to put it out, some of the bigger fan bots could blow it out from the doorway.

Thanks for the blast from the past. Let me know if you get it running, once Covid lets me travel I’d love to see it in action.

We should start the fire contest up again as a summer activity.

There was a big cleanup a few months ago and it was found hiding on the bottom of the box with defunct extension cords and other discarded odd equipment.

:+1:

Would be quite interesting to have various generations of the VEX hardware compete against each other.

thats not fair, because we all know v5 is waterproof for the water game.

Yep, the fire fight game is pretty simple. Sad part is once @DanMantz and @DRow launches the new game its all eyes on that. In the past the summer was on the fire game as a way to fill in the gap. Now we have 364 days of VEX challenges, I know there is the “eat the young” mentality, but to cross over to the Trinity Fire Fight and back would be cool. There are about 2 dozen robot things across the world and to go “Hey, my VEX robot just kicked …” is cool.

But in 4 weeks we can start Fire Fight challenges. I have a ton of M$NEY that I didn’t spend last year so maybe I can attach onto teams and build a league. I’ll reach out to @Dillan20785A to see if I can leverage their huge success with ORCAH.

And as an aside, you must have been digging deep to find that robot.
