I’ve designed and printed the electronics mountings for Android 12, for which I’ve mainly taken the electronics from Android 11. This consists of a plastic cage and two side panels to mount the microcontroller and two Pololu Mini Maestro servo controllers. I started with some old Ni-Cd batteries for testing but they appear not to have aged well, so they have now been replaced with a pair of new Ni-Mhi batteries – they are wired in series to feed a 12-24 input voltage regulator, which produces 5v at its output to power the servos. More pictures on the Android 12 electronics page.
Here’s Part 6 of Android 12, explaining the hip assembly and showing the entire bottom half of the android in one piece. More pictures over on the main project page.
I’ve added photos of Android 12′s thigh parts to the main project page. There will be more details once I get both legs assembled and attached to the hips.
Part 5 of Android 12 is up, explaining the hips assembly. More over on the main project page.
I’ve added a lot of pictures of Android 12′s hip assembly to the main project page. Video to follow.
I made a start on Android 12′s hip assembly. This will be multiple 3D printed parts due to the complexity of putting all three degrees of freedom into the space. More over on the main project page.
Here’s the next part of Android 12, the knee assembly is now complete. You can see more pictures over on the main project page.
I’ve added some pictures of Android 12′s ankle and shin assembly all together. Just waiting for some M3 studding to arrive for the pivots at either end of the shock absorbers, then I’ll have another video showing the motion and active dynamics provided by the gyro in each ankle.
