Arduino/CyberBrick Crane

Highly optimized crane for lightness and printing speed (47 grams in total, only 1gram support).

Model made up of 14 interlocking parts, requires a single 10mm M3 screw for the rotating base.

Educational project developed for a STEM course in 3D modeling with fusion 360 and Arduino programming with mBlock.

A base without Arduino holder is also provided, so it is compatible with CyberBrick or other programming systems.

All electronic components are standard and easy to find: Arduino Uno/CyberBrick, 1 dollar 360 degree micro servo motors SG90, LED.

The best way to control it is with a joystick module, I have attached photos that show it.

In the attached documents you can also find an example Arduino sketch for crane control: the software implements servo motors speed ramps (constant acceleration/deceleration) to avoid load oscillations
 

For more compact wiring you can mount a mini breadboard on top of the Arduino with this specially designed holder: https://makerworld.com/en/models/585916#profileId-507128
