Maintaining stocks of fruit flies in the laboratory is labour-intensive. One task which lends itself to automation is the production of the vials of food in which the flies are reared. Fly facilities typically have to generate several thousand vials of fly food each week to sustain their fly stocks. The system presented here combines a cartesian coordinate robot with a peristaltic pump. The design of the robot is based on the Routy CNC Router created by Mark Carew (http:\/\/openbuilds.org\/builds\/routy-cnc-router-v-slot-belt-pinion.101\/), and uses belt and pully actuators for the X and Y axes, and a leadscrew actuator for the Z axis. CNC motion and operation of the peristaltic pump are controlled by grbl (https:\/\/github.com\/grbl\/grbl), an open source, embedded, high performance g-code parser. Grbl is written in optimized C and runs directly on an Arduino. A Raspberry Pi is used to generate and stream G-code instructions to Grbl. A touch screen on the Raspberry Pi provides a graphical user interface to the system. This documentation describes the design and build of the hardware.

The pump can be switched from CW rotation to CCW rotation by closing contact between pins 11 and 12. \n\nIn the operation of a CNC router Grbl uses Arduino pins A3 and D13 for enabling coolant and changing spindle direction respectively. Here we use A3 for pump stop\/start and D13 for pump direction (CW\/CCW). Two optocouplers are used to connect the Arduino to the pump while maintaining electrical isolation.
