What it can do

Written by Robotheca from the project's documents.

KANI is a quadruped (four-legged) walking robot, a close relative of the KAME design.
Parts are redesigned for 3D printing in PLA without support structures or adhesion borders.
Leg articulation uses no screws for mounting the joints.
A newer 'BIG KANI' version uses MG996 servo motors.

Wiring and electronics

Notes written by Robotheca from the project's documents.

Main parts

An ESP8266 microcontroller board is the robot's controller.
Eight MG90S metal-gear servo motors drive the joints (BIG KANI uses MG996 servos).
Two NCR18650B 3.7V 3400mAh lithium cells form the battery.
A 5V UBEC regulator provides regulated power.

Connections

The two batteries supply power through the 5V UBEC regulator to the robot's electronics.
The repository includes a PCB Gerber set (KANI_ver_1.2) and Fritzing schematic files that show the connections between parts.

Incomplete documentation

How complete the published files are for rebuilding this robot, measured by Robotheca at commit b7f4323. It isn't a rating of the robot.

3D and CAD files20/20
16 printable parts (STL, 3MF), 7 CAD source files.
Robot description0/15
No URDF.
Add a URDF: the robot can then be seen in 3D and tried in the browser.
Parts list0/20
No parts list in the repository or linked.
Most points to gain: Link to your parts list, or add it to the repository (a CSV or a Markdown table) with quantities, prices and where to buy each part.
Software5/15
Built on arduino.
Link to your code, or add it to this repository. Explain in the README how to install and run the software.
Documentation5/15
README of 966 characters with 2 pictures; 0 build steps.
Write a README of at least 1,500 characters: what the robot does and how to build it. Split the build into at least 3 steps.
