Using the arm with VICTOR motor

[Kevin Sevcik]

Quick unrelated question. What physical motor are you using on the robot that was wired up to the Spike? There's a pretty short list of motors that you're not allowed to wire to a Spike, I'd like to make sure we're not making this change for no reason.

A Victor motor.

A Victor is a Motor Controller, not a motor itself. Is it a CIM? Fisher Price? Window motor? 555?

Well, I don't know

If it is a CIM or Fisher-Price motor it must be on a Victor. All others can be on Spikes. Since you said it's an arm I would guess CIM or Fisher Price, as the others are fairly wimpy motors.

Can you give a physical description?

Big, black cylinder: CIM
smaller, gray/silver cylinder: FP, Mabuchi
oblong with a diskish shape on one end: Window motor

Well, I'll see tuesday the type of Victor.

Sorry. but it doesn't work. I've tried to stack the case structures. I've made three print screens and will post it right now.

By the way, our Victor control is a 2.5 '' CIM Motor, 12V DC, 2.5'' diameter, and we were advise to use a Victor instead of a Spike because it's not allowed.







Thank you very much!

Just checking on the legality of things. Moving on...

Your code there looks good and should work. I think I see the problem, and we should have all noticed it earlier, but it's a tricky one to catch. I think you're accidentally using different names for your motor reference.

In the screen where you're closing the reference and the screen where you're controlling the motor, it looks like you're calling it [Bras Robot]

In the screen where you're opening the reference to the motor, it looks like you're calling it [Bras Robot ] with an extra space at the end. That extra space DOES matter and it means you're saving the motor reference to a different name that you're accessing it with.

So, I think if you double check all your references to [Bras Robot] and make sure they're all exactly the same, things should work for you. Copy / Paste works well here. You might also want to double check this for anything else in your program you're having problems with.

In case that doesn't fix things, what does the LED on the Victor look like when your robot is on and in teleop? Is it blinking yellow or is it a solid color? Does it change colors when you press buttons 1 and 5?

The type of Victor had better be 884. That's the only one permitted according to <R42>. The question is what type of motor you're trying to control.

An unrecognized reference name will be indicated in the diagnostic messages window on the Driver Station. Are there any other messages there that might tell you what else you should be looking at?
