April 29, 2021; The Biped Pedals
Five Slat Message Board #1
It has been a productive week. I have completed the creation of the pedal assembly and am pleased that it works well.
Top image: Here are the components of the pedal assembly. I’ve taken the time to create spreadsheet-controlled designs for these parts so that I can easily modify them if required at some time in the future (for other automata). Wood and metal work well for many things, but I can get better precision by 3d printing these particular parts.
Next image: Part of the challenge when creating the pedal assembly is to ensure that it is aligned properly as the glue is setting. I’ve built a fixture that I use to keep shafts aligned.
Third image: This image is simply a photo of the biped with the ring gears…to give me an idea of how things will fit together. When finished, the ring gears will be located somewhere proximal to where you see them.
Fourth and last image: This is the biped seated, reclined at his final angle, and with his feet on the pedals. Just before leaving my studio this evening, I filled in some of the voids at the top edge of the knees.
I’m not sure what my next step will be. I need to sit and stare at this thing for a while and run possibilities and options through my mind.
I have been playing with Arduino and stepper motors this past couple of weeks. I have been wanting to know if I could use 12v stepper motors to power my automatons instead of the 110vac gear motors that I’ve been using. Thus far my playground suggests that the 110vac gear motors are the best. I will be using a 110vac gear motor for this automaton.
