Projects

The 2x4 is the mockup for the automated screwdriver.

This group used 4 screwdrivers and moved them all. The machine controller is from B&R Automation. One unit includes digital I/O, analog I/O, programmable operator interface, and enough buttons for a simple machine. All functions were coordinated in ladder logic, but next time we may use one of the structured text languages available.

Mockups were made using wood before cutting the Bosch 30x30 aluminum structural extrusion. The goal was to drive 4 screws to secure the faceplate of a customizeable receiver hitch.

Students designed sensors into the machine using either inductive proximity or photoelectric thru-beam sensors from Balluff.

All the wiring was coordinated using terminal blocks and DIN rail from Allen-Bradley.

Pneumatics was the prime mover in all systems. Students could choose from a large variety of SMC actuators, as well as SMC filters/regulators, solenoid valves and flow regulators.

Some designs were more effective and accurate than others, but all were pretty different.
