I've come up with a device to manage the leg motion of bipeds (and possibly quads with some adjustment).
As I've mentioned in my Bipedal Motion thread (http://www.lbpcentral.com/forums/showthread.php?t=8255), you want your leg to perform the following steps in order :
1 - Upper leg moves forward.
2 - Lower leg moves down.
3 - Upper leg moves backward.
4 - Lower leg moves up.
This takes a while to set up using the built-in Sync setting of wobble bolts and pistons, but thanks to the new angle setting on switches we now have a better way to do this. :)
Parts :
A large cube of any material.
A small rectangle of any material.
A motor bolt.
A magnetic key.
Two magnetic key switches, set to Directional and with 180 degree angle.
Assembly :
Set the rectangle piece on the large cube using the motor bolt so that it looks like the hand of a clock.
Set the magnetic key at the opposite end of the rectangle piece.
Set the first magnetic key switch at the left or right edge of the cube, making sure to align it with the motor bolt on the rectangle.
Rotate the whole cube assembly by 90 degrees using Grid Mode.
Set the second magnetic key switch at the left or right edge of the cube like the first.
Use :
Simply connect a magnetic key switch to the wobble bolts at the hip of your walker, then connect the other magnetic key switch to the pistons or bolts at the knees of your walker.
Adjust the "Backward" option on your pistons and bolts until you get the desired motion. Then you can adjust the speed of the motor bolt on the cube, and the wobble bolts and pistons, to whatever speed you want.
Here's what you should end up with :

Hope you guys can get some use out of this. I know I will. :)
