Inchworm Drive contains information about the RedPower mod.
Template:ComputercraftInchworm Drive is a method of propelling Minecraft blocks using a RedPowerFrame Motors. It allows players to create all kind of vechicles, from mining drills to spaceships.
How it works[]
Every direction of movement requires two frame motors to operate. Both motors must face the same direction. The movement has two phases:
First motor moves the second motor by one block.
The second motor moves the whole frame by 1 block, along with the first motor. Second motor stays in place.
It's important to provide Bluetricity to every motor in both phases (it's not shown in the picture!) and a redstone signal. The top motor mustn't have a frame block above it in the first phase, unless it's Covered. In the second phase, a frame above the second motor is obligatory!
