Building an r/c crane capable of lifting and rotating 2.2 lbs. Have constructed the crane with a base on a ball bearing lazy-susan for rotation of 90 degrees. The question is: how to attach the crane base (2.38"OD plastic pipe) to a servo for rotation control. Any ideas would be appreciated. Thanks.
Ln_r1 ideas is very good, but I prefer the gear is on lazy susan side. So the motor is in vertical shaft position.
Because getting gear at lazy susan periphery is not easy, alternatively you can install a large gear below lazy susan (common shaft with lazy susan).
More easy, use pulley. Either lazy susan rim as pulley or install large pulley below lazy susan (common shaft with lazy susan).
