=== Cassettes === | |||
I want to use removable cassettes for each type of topping. These need to be dishwashable. I'm planning on making them out of a suitable plastic, probably by modifying an existing container. They need to be modified to hold a grater blade on the base. This takes the form of a sliding sheet half of which is a grater or mandoline blade and half of which is smooth plastic. | I want to use removable cassettes for each type of topping.

== Rails == | === Rails === | ||
There are two components which attach to the hopper and grater respectively. Both of these ride on two smooth rails which stand above the pizza surface. There are also two screws (lead screws ideally, but threaded bar will do) which move the holders back and forth. Each holder is linked to one of the screws. The two screws are rotated by geared motors at the end of the screws. | There are two components which attach to the hopper and grater respectively.

The pizza base is just a rotating platform. It'd be good to have some form of position feedback on this, but not essential. | The pizza base is just a rotating platform. It'd be good to have some form of position feedback on this, but not essential. | ||

== Carousel == | === Carousel === | ||
The carousel holds a series of different food cassettes which move on a linear belt. The main transport can place and remove things from the carousel, so it only needs to move left and right to select the next ingredient. It'd be good to have some sort of barcode reader on the hoppers to determine which cassettes have been loaded in each slot. | The carousel holds a series of different food cassettes which move on a linear belt.

== Progress so far == | |||
I hacked together a mockup of the linear transport. [[image:Deighton-linear-transport-mockup.jpg|right|thumb|Linear transport mockup]] This is moving pretty well, but I haven't tried using it on food yet. I need to find a suitable supply of containers and graters that can be put together. Also, this version isn't clean so any food processed by it would be wasted. | |||
The transport uses steel bar from IKEA (http://www.ikea.com/gb/en/catalog/products/80138763) as its main rails, running in 16mm (outer diameter) steel tube from Leyland SDM, and M10 threaded bar. | |||
