Action Log
- 01/03/2008 - Bottom plate prototype completed.
- 02/15/2008 - Top plate prototype completed.
- 03/18/2008 - Ground clearance concerns have prompted investigating into correcting.
- Notes - Possible fixes, larger omni wheels, moving wheels down.
- 03/30/2008 - Moving wheels down has been selected for fixing ground clearance.
- 04/08/2008 - Standoffs for the electrical boards up to the shell have been found and overall height for the robot has been finalized.
- 04/10/2008 - We have decided to go with pressing for creating space for output gears on the bottom plate. This allows us to move the wheels down for additional ground clearance.
- 04/10/2008 - Cutouts for motor wires need to be moved in some to allow for more slack and connection with electrical board.
- 04/15/2008 - Die for stamping bottom plate gear allowances has been made and the process produces successful results.
- 04/22/2008 - Bigger cutouts for drive motor cabling, addition of antenna support plate, standoff change.
- 05/15/2008 - Standoffs changed and selected.
- 05/17/2008 - Mostly complete ball sensor integration accomplished.
- 05/21/2008 - DXF's for waterjetting all plates have been made and sent out for quote.
