second mutation of the Macropede legs
@ all

I brought the second mutation of the Macropede legs to live.

Two big changes:
- stronger hip segment with optimized geometry
- replacing 32x M3 screws and 64x M3 nuts at the hip
-> by 32x Ø5 mm plastic pin and 32x C-ring
This not only saves nuts and screws but also makes it much easier to assemble it.

I will use M3 screws for the rest of the gear axis because of it's stability and exactness. Additional this gives you the possibility to adjust everything for a good run.

Changed the crank radius from 5.2 to 5 mm and shorten the leg for 1 mm. Small changes only but big steps would take more time to do...

The 8 leg module with Sho's gearmotor takes less than 140 mA at 2,7 Volt = 0,38 Watt. But you can stop it easy by hand (sorry - no current for this).
This is good and bad because nothing can break apart...

Later I will support servos in the Macropede leg module also to keep costs down and make sourcing easy.
