THE FOLLOWING TABLES ARE COPIES OF 2018's TABLES AND HAVE BEEN LEFT FOR ILLUSTRATION ONLY - DO NOT USE FOR 2019! Please delete the above note and replace content of the tables below with 2019-relevant information once available.
Motors
| Mechanism | Action | Minimum Breaker Size | Motor Model # | Quantity | Notes |
| Cargo | picks up and deploys the cargo | 775 Pro | 2 | Starting with gear ratio 12:1 | |
| Elevator | moves the cube and hatch mechanisms up and down | 775 Pro | 2 |
gear ratio 16:1 | |
| Habitat | rotates wheels at rear two pistons | 775 Pro | 2 | gear ratio 49:1 | |
| Drive Base | Moves the robot | 40A | CIM | 4 |
Gear ratio 14:68 option to add two additional motors option to swap out CIMs to Neos |
Pneumatics
| Mechanism | Action - Say what extend and retract do! | Number of Cylinders | Cylinder |
Extend Powered?
|
Extend Exhaust to Atmosphere?
|
Retract Powered?
|
Retract Exhaust to Atmosphere?
|
Working Pressure | Estimated Firings per Match Cycles (Sum of all powered directions!) |
Notes |
| Hatch | Extend = raises the hook Retract = lowers the hook |
1 |
3/4" Bore, 1" Stroke |
Yes | Yes | Yes | Yes |
50 PSI |

Sensor Chart
| Mechanism | Sensor Type | Function | Attachment Point | Notes |
| Hatch |
limit switch Honeywell SZL-VL-S-B-N-M |
to confirm that we have the hatch against the backplate | Side-mount to vertical square tube "back stop" for hatch holder. Switch arm extends out ~ 1.5" into where disc would be held. Should be positioned just high enough to miss center hole on all possible disc approach heights for loading station. | |
| Hatch/Cargo |
Camera/vision (Still work in progress!) |
knowing that we are aligned with the port | ||
| Cargo |
Beam Break Banner Q106 |
knowing that we have acquired the ball | (Need to discuss current mount location) | |
| Cargo |
Magnetic Reed Switch Bimba MRS-.087-PBL-09 |
Sense that Cargo mechanism's cylinders are extended fully and out of way of using hatch mechanism. One on each cylinder |
Body band mounted on extended end of cylinder body | |
| Elevator |
Encoder VersaPlanetary Integrated Encoder 217-5046 |
a way to do vertical positioning | In the gear box on the motor | |
| Elevator |
