So, after one year of inactivity, we finally make the first version of Keeda walk.
This implementation is very different from the designs proposed by sush. Its very simple also. Using basics of BEAM, we replaced the quad inverter based motor controller ( effectively a motor controller :) ) with a pic 18F4550.
Writitng the program was rather easy. But making the whole bunch of wires, solidified glue, motors, and..... sillicon was took some time. Balancing weight, making sure that legs touch the ground at the right places are some of the key points.
The very initial version used to fall down after every 5-6 steps, which appeared cute to the observers, ( and frustrated us ... :) )
A: Hey look , it just walks like a baby,
Me: Yeah , we'r teaching it to walk...
A: Hey, it just fell down... and that looked way too cute....heeeee
Me:. Well that shouldnt have happened,, lemme see.. oh there is a problem with the motor..blah...blah...blah......
So, after one more week of "deBUGging", we were finally able to make it walk .... i mean for 2 minutes, without falling... yipee.......
and here are some more stills...
