Robotic Arm designed for automatic sample collection.

Taking inspiration from different industrial robotic arms out there, I modified the design to better fit with the current scenario. The arm I designed can be used to take automatic samples from the mouth and nose to test for the COVID-19 virus. It can automatically take samples from the patients, put the samples in a test tube and replace the used test tubes with new ones which avoids human interaction crucial for the current stage we live in. This is not in any way a finalized design, just an idea on how it would work if it were to be manufactured. If you have any doubts, please feel free to ask!
