Exercise 09/10

Mechanical Design and Machine Design

My part in improving the person scanner was the rotating platform on which the person stands. The full documentation of the work can be found on the project page.

The rotating platform consists of three sheets of 5mm MDF cut into a gear shape with our lasercutter. We had to cut the platform in two pieces because our lasercutter is only able to cut a 60 x 30 cm surface. Afterwards the three sheets are screwed together. Next a Lazy Susan rotating tray was screwed onto the platform to allow the platform to rotate. Afterwards we attached a DC Motor XYD-16 with a gearbox. The black circle is made of Polyoxymethylen and prevents the two MDF parts from rubing against each other when someone stands on them. The gear is generated with the Gear Generator from Inkscape.
