Trying to learn how to build a 6 legged robot from scratch....
I presently don't know how the robot leg mechanism and could find any beginner references..
can anyone post some references / guide me how to start with these?
Inverse kinematics is what you want to learn about.
There are various three servo hexapods on the net. Google and youtube searches should produce a number of designs that are fairly simple to build.
