:ohmy: im not sure that would work. first, the batteries inside the lego rcx wouldnt be able to power the motors needed to move the robot efficiently for a long period of time, and second, i would need to have several rcxs to control all of the motors and a lot of time to write the scripts for each rcx. but if i can write a script like the one on the rcx and run it on a mac, it might work and be easier to write than the codes for rcxs or a program for the mac thats written in some other programming language, and im not very good at programming so that would be good if that could work. so ill see if i can use that.
