Survival Friendly Mechanical Arm [Create: Aeronautics]

Linked Controller:
W = red wool;
S = blue wool;
A = yellow wool;
D = green wool;
Space = gray wool;
Ctrl = light gray wool.
A and D rotate the base counter-clockwise and clockwise respectively. W and S move the first arm segment up and down, but there's a clutch that blocks rotation to this segment if Space is held. Segment 2 can also be moved up and down, but only if Space is being held (red or blue + gray). Then, the claw can be opened and closed with W and S, rotated with A and D, but only if Ctrl is being held down, because it blocks rotation from the second arm segment and allows it on the claw (red, blue, yellow or green + light gray).
Each swivel bearing has a middle shaft and a small cog, which are used to transfer rotation and move the contraption body, respectively. I made it so there's always a shaft passing rotation through the bearings and to the next segments. That way, only one kinetic source can be used, and no addons like Create: Ender Transmission are necessary.
