Improved Ragdoll Walking Machine

I added a thruster in the back. To make it move faster or slower, change the force of that thruster - by default, 500. To make it turn faster or slower, change the force of the thruster on the side of the cinder block.
Original description still applies to this:
For the convenience of myself as well as fellow creators of silly Garry's Mod videos, this machine is uploaded. Just Weld whatever parts of the ragdoll you want to hold their pose to the red whatever-it-is, Axis the feet to the edges of the wheels, and Color the contraption invisible. Use the numpad arrows to move it.
