Lench Scripter Mod [Besiege v0.42]

Does anyone have an AI script that I could use for a robot or a transformer? I'm not really a good builder in besiege and have almost no knowledge of scripting or any languages, just that usual noob who likes to try/play people's things :)
Can someone please help me? I am a little new to scripting and I would like some help with a script to make a mech leg chassis move properly with use of the arrow pad. (Walk forward, backward, swivel the hip to change direction etc.) I have made one button mech chassis before with help from flying blocks but I want a more Walking War Robots (look it up) feel.
