Fluffy
This is my first walker.
Named Fluffy.
Worked well but for one problem.
You should always pay more than $8 for your servos.
Had 20 servos, used 8 for the legs added 1 for the torso.
Let the magic smoke out of 13 of them then gave up.
It used a linxmotion servo controler board and a bluesmirf running off
a laptop.
Now makes a cool paperwieght.
Conclusion
Dont ask too much from cheap servos.
