“Did you ever think about designing a manipulator claw using servos? Today, Im going to show you how to control a servo robotic claw using an Arduino Uno.
I used two claws to do this. One was made in a 3D printer, and all of its parts were printed on ABS plastic, which I prefer as its more flexible and less brittle. The second claw is acrylic and was cut by a laser.
In addition to the claws and the Arduino Uno, we use four micro-servos (3 Tower Pro MG90S and 1 SG90), a 10k potentiometer, as well as a protoboard, wires, and elastics.”
