Robotic arm - 4 servos

Development Boards Arduino
1

Hi!

My project idea is to control a 3 joint robotic arm with 3 servos, and rotate it with a fourth one. The arm control would be done by a software, which track an area in real time, using a mark on the area as origo. When the arm start to draw something on paper, and i move the paper it should correct itself, based on the origo mark.As a newbie to the Arduino, i like to ask what is the best board to control servos, and some other electronics like lamp and vent.

The feedbacks are greatly appreciated!

An Arduino Uno would be fine for this. To control servos you need pins with PWM capability of which the Uno has six.

If you’re only looking to control servos (and a few digital I/O) from a host computer then you might be happier with a servo controller such as the Pololu Maestro series. That would eliminate your need to do any programming on an Arduino.
