Here is latest update:

I built the stabilizer for the booster, since the magnetic booster cannot control the radius os gravitational force generated around it, need those stabilizer attached on tip of the mechanic arm.
Those arms are articulate so can "squeezing" down the magnetic field pointing the force to desired direction and applifying it.

The base ring with arms are attached are consisted with outer ring with can move the arms around it, and inner ring with give electricity for the stabilizer, so does not need "cable" connected direct to stabilizer. (I took that idea from the train rail, that gives eletricity to the train "every morning I need to take a train, so was something that bright me up when I was waiting for")
