This is a simple 4 leg walking robot base. The rear legs just shuffle back and forth but the front legs take steps.
You can use any of the TT type motors. I used the 1:90 as it is a nice walking speed. The motor is held in place with 6-32 screws.
Add 2 small rubber gromets to the front legs for added traction.
I used 2 AA batteries for power.
I also use a slide switch with 19mm mounting holes for the ON OFF control.
The linkages that connect to the motor cam's are held on with 6-32 by 1/2-inch screws.
The other linkages are held together with 6-32 by 1/4-inch screws.
