How To Design A Mechanical Ping Pong Ball Sculpture

submitted by newtboy

5 months 3 weeks ago

Proudly Presenting: "Corporate Ping Pong"

This engineered mechanical sculpture is a representation of the hum and haw and constant, slow churn of the big corporate machine. Jumping through hoops, creating flair, but not very much actually getting accomplished.

It is a kinetic sculpture made up of many moving parts. The pingpong balls are lifted with a 12 way geneva mechanism, which is timed to drop a ball into the launcher scoop every 10 seconds. This is coupled to the archimedes spiral cam via a chain and sprocket, which charges the plunger mechanism with elastic potential energy. At the end of the cam, the plunger is released, popping the ball into the air for a brief moment of excellence, before making its way back into the queue, only to do it again.
