Versatile Arduino Arm Creator Needed

Job ID: 37897089

Budget: ₹1,500 – ₹12,500 INR

I am in telecom industry and I wish to participate in one of an upcoming exhibition, wherein I intend to have a robotic arm which should be capable of doing the following:

Unlocking a Android Mobile phone by dialing in the passcode
Open the phone app
dial a number from the history

In order to keep the movement to minimum, we can have a same 6 digit passcode, and we can place the phone in a way that the position of the passcode key aligned with the intended called number last position

It should be able to be operated by a standalone computer connected to it, as I might not get WiFi in school where I will be displaying it
