DARPA's Pet-Proto walking robot navigates obstacles

In this new video released by DARPA, the Pet-Proto autonomously navigates a similated urban disaster environment. It can step up onto ledges, jump off landing on two feet, decide how to cross an open gap in the floor and fairly quickly scale stairs. Impressive.

How to use microcontroller to stand in for joystick

I wasn't sure if I should post this in another forum or not. I consider it a beginners question having to do with electronics but I need to give some back story.

How expandable is the Picaxe-25?

Hello All.

I'm looking to build the "Start here" robot so I can learn some basics but I want to know how expandable the Picaxe-25 project board is. I would eventually like a robot with more than two motors but it looks like the L293D motor driver can only handle two motors at a time. Is there a way to use the Picaxe-25 project board to drive more than two motors? Are there other chips that will fit on the Picaxe-25 besides the L293D that will drive more motors?

I'm trying to see if this board will be able to grow along with my ideas/skills or not.
