| Task | Deliverable | Demo | Demo Date |
|---|---|---|---|
| Combined carrier and shaft prototype | A single part that fulfills the role of both carrier and shaft | The piece fits properly within the ring gear and around the planetary gears. Simple to manufacture | 2/21 Machine prototype out of plastic |
| Battery housing | Battery housing for 5 batteries with wires that connect the batteries in series | The batteries are wired in series supplying a voltage of 16.5 V with the wires neatly placed in the housing | 2/28 dimensions and preliminary drawings for battery housing; 3/7 16.5 V test |
| Make a CAD model | CAD drawings and assembly files | Shrink current Gibbot to within 15% of all physical parameters found in Kinea's Gibbot. | 4/4 place all finished CAD drawings in repository. |
| 3-D print frame | A 3-D printed frame of the Gibbot | An assembled prototype of the frame | 2/28 quote for printed part; 4/11 robot frame |
| Generate materials list | materials and vendors documented on wiki | None | 4/4 materials on wiki |
| Generate a list of potential vendors to fabricate robot | list of vendors, pricing, lead times, and files needed for fabrication | None | 4/11 submit vendors |
| Task | Deliverable | Demo | Demo Date |
|---|---|---|---|
| Design double pendulum | A double pendulum that can swing freely with LED markers for tracking, a motor, and a space for electronics | double pendulum attached to wall | 2/21 place order for all materials; 2/28 assembled robot |
| Implement electronics on robot | put an H-bridge, current sensor, XBee, and PIC on the top pendulum's link | show pendulum swinging under PIC control | 2/28 show pendulum swinging |
| Implement PI current control | PI controller with tunable gains that can be set over XBee | plot current over time and show current converge to desired current value with gains tuned in real-time | 3/14 demo current controller |
Redesign PCB to work at 24 V | A PCB with no PIC resets when motor is operating at maximum power (limited by power supply) over an extended period of time | Motor is operated at full power for a 24-hour period with the PIC sending a “heart beat” to the PC at 50 Hz without any resets logged by the system | 2/21 (rush) order new board; 3/4 24-hour test| Automate PCB assembly | PCB "coordinates" file, cost of assembly, and instructions on wiki on how to create coordinates from Eagle | Anyone can their own "coordinates" file from reading the wiki alone | 3/15 wiki is ready|
