Stopping When Home is Found

A project log for Little Friend

This companion robot, 9000 farads of super capacitance, spends less than eight minutes feeding--then 75 minutes or more she can be a buddy.

On Taco (the homing station), a magnet will be found by Mato to indicate that she has arrived. Today, the bracket that holds the magnet sensor and rods (for Taco's recharging fingers to clamp onto) has been printed (file available on this site) and installed.

Here are the parts--3d printed bracket, rods, magnetic detector circuit.

The magnetic detector circuit slides in here.

The assembly looks like this.

Of course, it will have to be wired up--matched to Taco's magnet placement and software will have to be revised. The idea is that Mato "sees" the station and drives in, then stops when the magnetic switch is activated. Taco will then clamp on the rods and recharge Mato--then release and Mato will back out and play again.
