  • Motion control and its ground-based experiment of a tethered subsatellite with a controllable rigid arm
    There are four groups of actuators to control the position and attitude of the simulator. Four solenoid valves, in two orthogonal directions, are mounted on the satellite simulator for position control. The DC/DC converter converts the output voltage to + 12V , ±15V, and 5V. The reaction wheel can provide a linear moment to control the attitude motion of the satellite simulator. .

  • CR4 - Thread: 12v Controlled Lens Covers
    I was thinking along the lines of 4 linear actuators but these dont seem to retract when 12v is removed( has to be reversed polarity to pull the cover away), Solenoids would probably work better....with some sort of rc 4 channel controller.
