 | | Looking for orthogonal motion
|
|
Hi all, I haven't been able to find anything on the net about a Lego implementation of an orthogonal drive system using only motors (i.e. no pnumatics). Orthogonal is when your your chassis can go straight forward and back, and also side to side, (...) (24 years ago, 12-Apr-01, to lugnet.robotics)

(...) You could make a big wheel made of lego plates, and put smooth ones on top for 'colors'. Then you could use a touch sensor, and use the difference between the low spots and the high spots as 1 location. Do you really need to know the direction (...)

Hi David, I have built a robot that does this for a university 'robot maze solver' project. My solution is big, ugly, very slow and pretty complex. It could probably be improved a lot if it was redesigned. However, it uses 3 motors (1 for (...) (24 years ago, 12-Apr-01, to lugnet.robotics)

I downloaded the program from RCX Command Centre to my scout. I then pressed run, but it didn't run the program. It wasn't to big because it was it was only 'On(OUT_A);'. Does anybody know what to do? TNX (24 years ago, 12-Apr-01, to lugnet.robotics)
