Last year for the Curtin Robofair Brett had gantry crane working based on two winches. While functional the device could have been larger, worked in THREE dimensions and be enclosed in laser cut acrylic. So for this year's Robofair a few of us decided to implement these improvements. Unfortunately for Brett most of the skills reside in his brain, so he is the busiest with implementation.
Designer, Machinist, Coder & Funding - Brett Downing - he started this projected and much still resides in his brain.
Laser Cutter Operator, Trouble-shooter & Funding - atrophy - the laser cutter for a local trade school allowed the pretty acrylic housing to be made.
Logistics, Project Management & more Funding - Jason Muirhead - driver, lifter of heavy stuff and trying to keep the others focused and when they are focused getting out of their way.
3 motors from cheap cordless drills
6 mm clear acrylic
3 mm black acylic

37 mm aluminium rod
lots of bearings (final numbers and types TBA)
various other fasteners (final numbers and types TBA)

Designs for cutting the acrylic will be available on Thingiverse.
Arduino code will be avilable on github.
Pictures of assembly will be posted soon.
