Have just received the two motors that will power Dangly Too.
These are large 12 volt 421 rpm motors, that should give him plenty of power driving his over-large wheels. They use a nice epicyclic (planetary) gearbox arrangement, which run smoothly even down to around 20rpm at 0.9 volt.
On the original Dangle, we used motors with a worm-drive gearbox. This gave a lot of power, but was very hard to control and they were heavy. Stopping the motors abruptly stopped the wheel and in turn caused Dangle to do cartwheels. This coupled with a lot of play in the gearbox meant we had a hard time doing any accurate turning or positioning.
Next up, deciding what we will use to drive the motors?
Should we drive directly from the Raspberry Pi using a suitable motor hat as we did previously (Redboard+)?
Or should we use a Pico to do the low-level driving and take this load off the main Pi?
Can we wait for the new Pimoroni Yukon boards?
