Specs from CMU
- Dribbler motor gear from SDP-SI: S10T05M042A0303 Module 0.5, 42 Teeth, 20° Pressure Angle , 2024 Aluminum alloy Gear
- Dribbler bar gear from SDP-SI: S10T05M028A0305 Module 0.5, 28 Teeth, 20° Pressure Angle , 2024 Aluminum alloy Gear
- spur gear reduction 1:1.5
- Dribbler Motor - Maxon
- 266521
- http://test.maxonmotor.com/docsx/Download/catalog_2007/Pdf/07_154_e.pdf
- nominal speed 28200 rpm
- Gearhead
- 118184 - Maxon
- http://test.maxonmotor.com/docsx/Download/catalog_2007/Pdf/07_215_e.pdf
- reduction 5.4:1
- nominal dribbler bar speed = 28200/5.4*1.5 = 7833 RPM. It is, of course, adjustable by software.
