For the sake of it, I wanted to see if I could make a really simple biped - and this is what I came up with :)

I thought it was really fun to do, much more than expected, I can recommend it :) if I can find the time, I would love to do some other versions of this kind of simple moving creatures.. a couple of servos, wood, glue, Picaxe, back to basics, good fun :D

Looks like you're getting close.

I posted a comment on your robot page. I wanted to link back to your page from here in case anyone else has this same problem.

Look at all those beautifully capitalized words. I'm going to have to find something else to be grumpy about.

Cheers for the advise, Fritz what dimensions are your robots feet and neck piece?

Sorry but I'm out traveling the next two weeks so I cannot check.

Under all circimstances you are best off estimating, testing, improving. That's what I'd do myself if I was to remake the robot - even if I had it next to me.

You will have to get used to testing, it's part of building. It's not possible to copy a robot made by hand, you are making your own version, and it'll have to be made by you.

When you come to the software, you will have to spend at least a day just optimizing - at least. It's common to work on it for a week before it's working as you intend.

Hi guys I have finished the walking and tricks side of my biped robot, cheers for all the help, now I want to add a SRF05 sensor, please could someone tell me how to wire it up, like which pins I am meant to hook up to my AXE231  microcontroller. I will post a video on Youtube soon of my robot walking, thank you!

Im gonna  take borrow this form of locomotion. I think i'll try to make a humanoid out of it :). Oh! And if you wanted to use the least amount of actuators, one could've used a custom geartrain and a single dc motor. The drive train would work by moving a leg to the corresponding direction the motor is rotating. If it rotated more one way, the biped would turn. 

"if you wanted to use the least amount of actuators, one could've used a custom geartrain and a single dc motor."

Actually, no - if you read the code, you will see that there is a great deal of time-tweaking done - individually for each side.

Looking forward to seeing your project :)

This I s brilliant!!!! I've always wanted to make a bipedal and this one doesn't look to hard!!!
