A Bear's Operators Chair
In order to make the joysticks work I need to shorten the actuator movement down into the mechanism. If I extended the lever arm straight down into the mechanism the movement length would be too long. So I fabricated a lever arm to change the direction into a vertical movement which would be easier to configure. To do this I built the lever into the arm of the chair to hide it. Because of the tight space it was necessary to hollow out space for the linkages.
The link to the polar bear's hands also had to be installed during assembly. The following photos show the assembly process.
