I'd like to buy a capacitive touch input robot in order to remote access my iPad but I'm having trouble describing a correct kind of robot.

I would like to keep lag down to an additional 60ms so that it is still a high quality interface.

I would like to have a robotic arm equipped with a capacitive pen that moves to places on the ipad screen based on the mouse or I'd like a array of capacitive pens that emulate the touch of a user.

I guess I'd use Squires software reflect and the mirror function but I'm open to using an SHD camera with the robotic arm and a pixel sensor array with the array of capacitive pens.

Does this make sense? How could I improve the design? What materials would I need to build it myself. Assuming ready built arm? How could I build an array of capacitive touch micro pens?

Since the screen of an iPad is your desired workspace, and all the arm will have to lift is a stylus, this will not have to be a large arm. There are many "hobby" arms built with hobby airplane servos that will probably work for you. I won't list any makes / models because there are many out there.

I am not sure what your comment about lag is about, but if you want a fast arm, you should consider a Delta robot arm configuration. Because the "standard" serial arms mentioned above are not very fast. These are harder to come by. the only hobby level delta arm i have seen was the Robot Army Starter Kit on Kickstarter.

  • $\begingroup$ what about the other design with an array of styluses? $\endgroup$ – user3949 Mar 3 '14 at 6:01
  • $\begingroup$ also would this work amazon.com/dp/B00HO15O54/… ? $\endgroup$ – user3949 Mar 3 '14 at 6:25
  • $\begingroup$ Yes, this is exactly the type of hobby servo driven arm i was talking about. But you might be able to do better by making a custom 2D arm because you only need the arm to move in the plane. (plus 1 bit of stylus up / down). $\endgroup$ – Ben Mar 4 '14 at 1:51
  • $\begingroup$ great, how slow would it be? who could I get to write the software? $\endgroup$ – user3949 Mar 4 '14 at 5:30
