Lego motors

How can I connect lego motors to the NXT/hightechnic motor controller? Also, how do I use them in code? Are they like regular motors? I've been searching everywhere, but I can't find an answer...

Re: Lego motors

You can't if I know what you are talking about...Tetrix 12 DC motors instead of your Lego motors.

Re: Lego motors

They're orange and different shades of gray, they look kind of like the tip of a crane.

Re: Lego motors

Can you send a link to the page where you bought them. You can't use it what I believe.

Re: Lego motors

Probably what you have bought is this http://www.hitechnic.com/index.html?lang=en-us&target=d14.html
The first one!
This should be in another forum I believe.

Re: Lego motors

We have those electronics, but the controllers had a black covering.

Re: Lego motors

Re: Lego motors

So the lego motors definitely cannot be used with a hightechnic motor controller on plugged in directly to the NXT?

Re: Lego motors

No but why don't you use the other 3 ports on the NXT

Re: Lego motors

You have to activate it in the motor and sensor setup then copy this code.


	Quote: task main() { while(true) { motor[motorD] = joystick.joy1_y1; motor[motorE] = joystick.joy1_y2; } }

Re: Lego motors

So, you use Lego motors like regular motors in code? Do you configure them the same way? Because I tried that and it's not working.

Re: Lego motors

Motor controller on the sensor one (servo on the motor controller)
Check battery!


	Quote: #pragma config(Hubs, S1, HTMotor, HTServo, none, none) #pragma config(Motor, mtr_S1_C1_1, motorD, tmotorNormal, PIDControl) #pragma config(Motor, mtr_S1_C1_2, motorE, tmotorNormal, PIDControl) //!!Code automatically generated by 'ROBOTC' configuration wizard !!// task main() { motor[motorD] = 100; motor[motorE] = 100; wait1Msec(1000); motor[motorD] = -50; motor[motorE] = -50; wait1Msec(1000); }

Re: Lego motors

Sorry for my sample code here is one that makes the motors A B C on the NXT brick to run


	Quote: #pragma config(Motor, motorA, , tmotorNormal, PIDControl) #pragma config(Motor, motorB, , tmotorNormal, PIDControl) #pragma config(Motor, motorC, , tmotorNormal, PIDControl) //!!Code automatically generated by 'ROBOTC' configuration wizard !!// task main() { motor[motorA] = 100;//running motor A on full power motor[motorB] = 100;//running motor A on full power motor[motorC] = 100;//running motor A on full power wait1Msec(1000)//take time running motor A, B, and C on full power for 1 second } //ends the program

Re: Lego motors

FYI there are lots of samples in the sample code directory that use the NXT motors.

Also I've noticed alot of people are posting code with PIDControl turned on. I guess that's the default.
My personal experience is that this causes more wackiness than its worth. At least start with it OFF then turn it back on when you need it.

I know the great RobotC folks probably spent alot of sweat, tears and blood getting those things tuned, but I haven't had a single instance yet where they actually worked reliably. But it could just be me...
