Modelo 3D Robot Arm por Carlos Ghost no Printables

Descrição

Robot Arm uses the most common SG90 mini-servo motors and was powered by Arduino Nano.

Robot is very good helper in holding various small things (e.g. Soldering, Lights etc.).

Control for Robot can be with Joysticks or directly program routine.

Each servo have added a different step-down gear to increase the torque and reduce the speed to a reason manner.

 

Engineering Notes:

The waist servo have a speed reduction of 1:2 and 90 degree of rotation.

The upper arm servo have a speed reduction of 1:3 and 60 degree of rotation.

The lower arm servo have a speed reduction of 1:4 and 45 degree of rotation.

The base turning servo have a speed reduction of 1:5 and had extended the servo 5K VR from the servo in order to provide sufficient torque and 180 degree angle of rotation.

Six 4mm dia metal ball are required to support the base turning gear.

All servo motors are using the same gear of 9 teeth. This gear of 6 different tolerance/clearances are provided.
