Hi, I want to build a robotic application where an arm can press a switch and rotate a knob. Which robotic arm I need to pick for this? it is better if it is controled by arduino.

Hello. You might have more input from a site that focuses more on hardware if you're planning to build your own. One of my favorites is There are plenty of helpful people there, and many example builds with open designs.

 I  found a similar project:A Robot Arm base on Arduino with high precision 0.3mm and Opensource call dobot.This product will be soon on kickstarter one or two weeks later, please looking forward to it.   (

As for as controlling the I/O for the Servos that move the robot arm, an arduino would be a good choice if you want to make one yourself or buy one online such as:

However, if you would like your robot arm to press a switch and rotate a doorknob without being controlled the entire time, you can look into Moveit! ( ). Moveit! can be used with motion planning libraries, so for example, you could use OpenCV to recognize a doorknob, and Moveit! works with ROS to move the robot arm to turn the doorknob. This is mainly if you want to make your robot arm semi-autonomous though. If you just want to manually control the robot arm and have it rotate doorknobs and press switches, I would say that an arduino would be a good route to take.
