Well.... It's not a sex robot, but it looks like one when it moves.
The long cylinder pushes and pulls the large wheeled carriage which travels rather provocatively up and down the shaft.
Model aircraft pneumatic landing gear retracting solenoids lift up as the big thrust starts. Then the unit changes feet and strokes back.
All you have to do is hook up an air source and this robot will walk across the floor.
Everyone that has ever seen it has laughed out loud.
√ Video coming soon....... stay tuned.
