Power Functions like Remote for NXT Control

[Someonenamedjon]

Just came out of hibernation! (jk)

I was wonder if you guys would know how to build a forward/backward power control thingy like the power PF remote. It would be great if the "throttle levers" as one could put it would move straight forward and backward and connect to one motor for each so that I can control another NXT with it.

Sorry if it sounds a bit confusing!

It does indeed sound a bit confusing

Do you want to use two NXT units? Care to elaborate a bit?

[Someonenamedjon]

Yeah... NXT TO NXT control.

[Jim]

There are loads of examples for NXT to NXT controls. I would need to do a search, but I bet you will have lots of hits on Google.

Are you interested in the software or in how it's built?

[Someonenamedjon]

How it is built, as I did build one, but if you wanted to go to 100 power, your wrist would be a bit strained turning the lever to 100 degrees.

There's also a very nice EV3 Joystick! (let me find it for you)

EV3 Remote Control

There was a remote-controlled 'blimp' sometime back, where the builders used the NXT as a remote control, driven by two motors as joysticks. I think they used the motors as 'angle sensors' only. I can't think of the name, but they used the large/white propeller blades to move/steer the blimp. It was showcased at one large lego event in Denmark/Copenhagen(?)

Actually, the robot i am using is one that has two spinning wheels on the front and back, and two powered wheels on the right and left. I was hoping to get some sort a remote similar to the PF remote's design. The joystick you provided would not have been able to make the robot spin in place. The problem I am having is how to connect the two back and forth levers up to two motors so that i can read the degrees and send it to the robot.

thanks for the help though!
