The drive mechanism currently being considered is a lead screw. This seems to be the best option but others may be considered.
To press button, may want to use the screw driver mechanism - spring back to prevent going through the keyboard.
A metal prototype, with proper actuation seems to be the next obvious step forward in this design cycle for the gripper. Something else to consider is the available budget. This project is relatively small compared to other projects such as drivetrain or arm - these projects will need a much larger budget. It might be considered to dive into a final design to save on costs, with the exception of the motor. The motor can be swapped along with a bracket once motor power requirements are verified. This way if things work only a few parts will need to be swapped out.
