Well the other day I built another dual servo controller so now I have three controllers.

Ive got a full sized bipedal robot with six degrees of freedom. I have only to calibrate it before I write software to make it walk

I decided to take a break from vision processing and finish off the legs for my biped. (I hadnt looked at it for a while). I spent ages trying to figure out why it wasnt doing anything. I reburned the program into the micros, stripped the thing down and put it back together and was pulling my hair out until I realised the servo connector was in the wrong socket! - Duh.

Put it in the right one and what do you know it worked, must be a miracle.

I finally figured out how to get video streams and still pictures from webcams and analog video cameras in C/C++. (It was a lot easier than I'd been led to believe)

I did some simple vision stuff on my older android project but that was simple statistical motion detection, and that was using somebody else's program to grab time lapsed frames for me.

Now I know how to do that myself, Im going to have a go at the hard stuff.

Whilst Im waiting for the circuit boards for my bipedal robot to arrive, Im going to brush up on all the stuff I learned about boundary, region and edge detection and have a little play.

- Motters was it difficult to use two cameras simultaneously?

Ive added another degree of freedom to my bipedal robot. Now it can balance on one leg! Wont be long until it walks.

Well Ive been closely following James Brutons robot designs and have come up with my own full sized biped mechanism based on similar principles.

I tested it last night under manual control and I think with a bit of tweaking, pretty soon I may have something that walks.

I had a look at James Brutons design for bipedal locomotion and Ive had a go at making a similar project for my Android. Now I think it is possible to make a simple human sized biped using a minimum number of components.

I saw the new star wars film yesterday, you guys have to see it. I actually think its the best one in the series!

When I was a kid star wars was part of the reason I got interested in robotics in the first place. I always loved the way Lucas made the droids look so natural and normal.

In this new flm R2D2 is seriously funky and has loads of new features. I think Im going to dig out my old R2 unit project and put some decent features on it. - I was running out of imagination for my projects until I saw this film, Its definately worth seeing.

I've had a bit of roboticists block recently. Its gone now. I find that you start an ambitious robot project, you build it half of it and test with some software. If youre not careful Before you know it the test software turns into the final app and you run out of ideas because you've created a robot that only does what to you tell it to.

Well Im over that now. I've decided what I want my robot to do and more or less how to do it. I used to rely on windows to do all the control timings (bad move) anyhow Im going to use PIC for all that now. Watch this space.....

Have you guys heard about the bizarre developments in robotics in the United Arab Emirates? it sounds like something out of Star Wars Pod racing or something. They are trying to stop children from illegally riding camels in races and are proposing to replace them with humanoid robot jockeys (!?) see the link here

My girlfriend invited all of her friends round to my flat to meet up because we were all going out for the day. I was a little worried that with all the junk and stuff in my room they'd take one look around and think I was a computer geek or something. Not so at all! They came round, saw the droid and insisted that I showed it to them working, those girls wouldnt leave it alone after that!

I dont know if you guys ever get this but I think I've got cyberneticists block at the moment. I used to find that with mobile robots after you've built them you go back and can make them do cool things like programming them to go to a certain point in space and return, or use A* path planning etc. With mobiles there is always something new you can do with them.

I've found that with humaniod robots however after I've built the basics of the torso, I get to a point where I can program the arms and waist to go to different locations, open/close grippers and things like that but I dont know what else to do with it now. I've got cameras and lasers and stuff like that but I think Im running out of imagination....
