Servo assignments

Can you help me with the assignment of servos to specific connectors on an FSLBOT?

That is:

Left Ankle = connector?

Left Hip = connector?

etc.

Looking at the comments in fslbot_accel_graphic_walking.see, I find:



//for( servoa = 128 )

// J37=leftankle, J35=lefthip, J31=rightankle, J33=righthip

// J31, 33, 35, 37

AVRStudio5

as I was installing all the AVR tools on my Linux box I kept reading about this great AVR Windows tool from Atmel called AVRStudio5.  What really intrigued me was that it supposedly came with a simulator.  Since the ISP programmer I had does not support JTAG, there is no way for me to debug my code in hardware ( I would need a AVR Dragon for that ) so a software simulator is a necessity.  So, I turned on the last remaining Windows computer in the house and installed…

Automated labyrinth Maze solver

I am writing this blog post because I wanted to ask an open question that could be discussed in detail. I am open to suggestions and criticism. I have posted this on several forums and took valuable suggestions in building the system. I am stuck at a stage where I am totally clueless in solving the problem.

 

I used the following video as my inspiration:…

My Motorola Atrix just got updated to Android 2.3.4 (Gingerbread)
