RKMIX automatically mixes a set of RummyKub pieces and spits them all out on the table lying face-down.
RKMIX has 3 components:
- mixing drum
- colorSensor
- switch and turn-around mechanism
mixing drum
The mixing drum is driven by a pair of stepper motors Schrittmotor MOONS 1454HS5405-01N - NEMA 14 B - 1,8Grad.
- If the motors turn in the SAME direction, the drum is rotating and therefore MIXING the pieces in it.
- If the motors turn in the OPPOSITE direction, the drum carriage will be TILTED in order to empty it into the sorting Chute.
mix drum motor drive
connection to A4988 driver
one driver module per motor (Schrittmotor MOONS 1454HS5405-01N - NEMA 14 B - 1,8Grad).
motor has 2 coils:
- A-C coil
- B-D coil
Thus, 4 wires
driver has 4 outputs
- 1A, 1B
- 2A, 2B
| Wire | Wire color | Connector pin number | driver output |
|---|---|---|---|
| D | BLUE | 1 | 2B |
| B | RED | 2 | 2A |
| C | GREEN | 3 | 1B |
| A | BLACK | 4 | 1A |
