Minibot Simple Circuit

My bad on the "2way" vs "3way"

but, it does not make a difference which switch is used to deploy and to stop. depending on the way the motor is wired, one switch makes it go up if triggered first, while the other makes it go down if triggered.

A couple of corrections. The switches you are using are called 3 way switches. The deployment is via switch 2 and the braked descent is via switch 1.

The motor is also shunted ("braked") while in un-deployed state. This could also be a design advantage when trying to engage the pole.

Although we have yet to start the minibot, I've been thinking about using a layout like this to control the motors. I quickly sketched it up to share:



S1 is the "pole" switch, which is activated while the minibot is touching the pole.

S2 is a switch that is activated at the top of the run. It disconnects power & shunts the motors together, slowing them down.


S2 is tricky, though. It needs to be a SPDT toggle switch, not just momentary. Also, it needs to be "break before make" style, otherwise you'd short the battery & blow the fuse.

S2 can be a 3-way light switch.
