Once you have all that, you can probably use the RCX's sensors to rig
up a remote controller for your arm.

Thats the exact problem I'm having. I would like to have 1 RCX be able to
control the direction of 2 motors. So what I trying to make is a 4 button
controller using 3 touch sensors.

For instance, I want to have 1 RCX control the opening and closing of the
claw, and the rotation of the wrist.

It is even theoritcally (my spelling stinks) possible to use 3 touch sensors
and control both forward and reverse of 3 motors.

Like this:
Given Touch sensors A, B, and C
and Motor outputs 1, 2 and 3

Depressed Switches

A: Forward 1
B: Reverse 1

C: Forward 2
A+B: Reverse 2

A+C: Forward 3
B+C: Reverse 3

I started working on a controller which allowed 3 sensors the ability to
control both directions of 2 motors, but i'm sure it will take more time.

(...) You should be able to get 3 sensors to control 3 motors like this: Sensor A not pushed = forward Sensor A pushed = reverse Sensor B pushed and not C = Motor 1 Sensor C pushed and not B = Motor 2 Sensor B and C pushed = Motor 3 -Kyle (22 years ago, 10-May-02, to lugnet.robotics)

By making a good programming you can control lots of functions with one touch sensor, wich would be complicated but it's possible. I have tried using two touch sensors to control motors, let's say you press the sensor once for motor A, twice for B, (...) (22 years ago, 10-May-02, to lugnet.robotics)

(...) Well, with three touch sensors, you can have (at best) only 8 possibilities at any instant - but with even only one touch sensor, you can input any conceivable command if you have enough time. (Imagine if you entered your commands in morse (...) (22 years ago, 11-May-02, to lugnet.robotics)

(...) I've used a collection of four Scouts driven by IR commands from an RCX to drive a total of eleven motors. Just program the scouts to read simple 1-byte messages sent from the RCX - use the top two bits to select which Scout you are talking (...) (22 years ago, 10-May-02, to lugnet.robotics)
