7 Hand-sketched Draft Designs Early thoughts about required parts and arrangements

8 Ideas, sketches Altium Designer Schematic Schematic library parts Design cycle to refine schematic: When main structure was refined: Schematic Printed Circuit Board Schematic manipulation Review, checking datasheets, team feedback Determine issues with current design

10 Specify physical shape of board Place plated holes for mounting Component footprints and nets specified from schematic within same project Arrange parts across top and bottom layers Wiring and access requirements of robot Complexity of routing tracks between components General aesthetics and tidiness Remap pins, route tracks, draw silkscreen Submit for PCB manufacture by Entech

11 2D View Useful during design 3D View Useful for seeing how parts fit together vertically

16 Location:Swinburne University, Melbourne Date:Tuesday, 24 th September, 2013 Set up, calibration and testing allowed on 23 rd 16 teams passed the 4 milestones to enter comp. 3 qualifying heats, 8 teams progress to finals 1-on-1 knockout finals, increasing in difficulty Prizes for winners, runners-up and best design

17 Travel from starting point to mining camp Pick up the one gold cube Move to drop-off point (blue tape corner) Our best heat was fastest of any team

18 Entered finals in first place 1-on-1 against a team that struggled to make it to finals Got off to a good start, but…

20 The electronics needs for this competition were met, with a solution that is: 1. Professional Designed with Altium Designer, as used in Industry Manufactured using modern processes 2. Fit for purpose, yet expandable Connectors, ratings and functionality chosen for robot Adjustable voltage regulators, spare IO headers 3. Successful overall Robot was capable of completing task competitively Despite unfortunate result, positive feedback was received
