There is some interest at the moment on docking robots with thier chargers on 914pcbots.com. I see Chris Schur has posted his research document on this subject. Good stuff! I have posted a link to it on the other site.

Its funny the more advances I see in robotics the more it seems to tie in with human psychology and intraction.

Im going to pick up my Android PCBs from the manufacturer tomorrow. It took a while and cost a bit but its all ready now for installation.

The really annoying thing is that I designed the servo controllers to communicate to the PC via RS232 serial. In the time between giving my design to the manufacturer and receiving it I more or less redesigned it with USB electronics instead which are totally superior to my RS232 design in every way!

Got an email today from the guys that are making my android PCBs. Looks like they are going to be building them over the next few days.

I'll probably have something ready by Mid January. Annoying thing is they are only building the surface mount stuff so I have to do the thru hole stuff myself. Still it gives me a chance to replace the H bridge transistors with power mosfets for some serious robot kick!

Just in case any robotics guys in the Avon & Somerset region are interested, theres something going on at the HP labs.

Ive decided to have all of my Android Electronics assembled for me. I started building the circuits shown on my blog http://c6jones720cybernetix.blogspot.com/ by hand using Veroboard but I soon realised that with one SSC and up to 8 servo motors per limb, using Vero was just too much hassle. I dont mind paying a few hundred quid for the assembly costs. Im going to revisit robot vision in my spare time. I recompiled some of Motter's examples. He really is a true genius but I think I'll do things my way instead..

Lost all the work on my Hard disk! - How annoying thats about 4 or 5 years of stuff.

Did I mention Ive got a new blog? You can see the last android I built here: http://c6jones720cybernetix.blogspot.com/

Im working on a new one because the old one was too flexible.

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?
