You need at least 2 motors to drive your robot and sucessfuly control it.
and you realy need 2 motors (at least) to make your robot pre form a multi
task function.
So this is my solution to this problem. Get the lego RC racer to drive
your robot around. Then your left with all 3 outputs on the RCX. Last
you can get the lego mindstorm remote to excute you robots programs from a
distance.
any feedback on what you think of this would be gerate.
thanks

| I can only speak for myself, but I want my robots to be fully autonomic (turn it on and it fulfills it's purpose without any other interaction) I want more motors available as well, but some functions are only when the robot is not in transit, so I (...)

| (...) Now, what would be interesting is if you could sacrifice 1 motor output to power a mini radio-transmitter. Am I right in thinking that this could be quite small - ie a 2x2 brick encasing the crystal? How does the radio control car work anyway (...) (25 years ago, 21-Jan-00, to lugnet.robotics)

| (...) Why not use a second RCX brick? One RCX would be responsible for driving the system, steering it, and perhaps doing one other function, and the other RCX brick would be responsible for up to 3 other functions. The RCX's can talk to eachother (...) (25 years ago, 21-Jan-00, to lugnet.robotics)

| Hi, I made a reliable gearingsystem that allows one motor to control a "transfer". this way you can actually control 4 tasks with 3 motoroutputs (and 3 motors) If you have 2 RCXs, you can actually control 8 tasks with 6 motors. (...) (25 years ago, 21-Jan-00, to lugnet.robotics)

| Sorry if I'm a little late getting to this thread - It's possible to approach this problem mechanically. I used a gear - switching setup similar to the shuttle / the supercar to enable four motor outputs, two at a time. To do this, I ran the output (...) (25 years ago, 2-Feb-00, to lugnet.robotics)
