I have been putting in a lot of work on different components of my assembler, including
-Stepper motor build platform
-Servo driven linkage arms
-Linear base gripper
-Gear/worm material cartridge drive system
-PCB multi-stepper control board, employing APA for communication with other control boards
Here is some progress on each:
4 bar mechanism base gripper, 1/8" lasercut acrylic, various scales
gripper video
sarrus linkage translating platform
sarrus linkage platform video
stepper platform
stepper platform video
stepper platform video 2
folding arm watt's linkage, lasercut plywood and acrylic
arm video
material transport gear, 3D printed
material transport video
material transport video 2
Attiny44 running @ 20mhz, with 2 APA ports, and able to control two steppers.
