August 18, 2021: Proximity Sensor Mk 3
My inclination at this time is to create automata that are powered by motors, and that have sensors that sense the presence of a human (and that then turn on the automaton).
I am in the process of refining the proximity sensors that I use…making them smaller, more modular, and easier to construct.
Pictured are the three proximity sensor chassis and the biped. As I have constructed this version of the proximity sensor I am relatively comfortable with its design, size, and arrangement. This design or something very similar will most likely become standard on my automata. The three chassis give more mounting options that if everything was in one chassis.
One of the improvements that I have made is the choice of the on-off switch. I have been using toggle switches. This version uses instead a three-position lighted rocker switch. I find that it operates much more comfortably and easily.
I am also experimenting with 3D-printed hinges in the biped joints. You can see them in the knees, hips, and elbows. They seem to work well and I suspect that they will be very reliable. Time will tell. The hands are attached to the arms with magnets. This arrangement allows me to easily remove the biped from the automaton. There are also magnets in the shoes that attach to the pedal.
