PACKAGING TESTING DEVICE
A testing device including a base having a first joint and an arm. The arm has a first branch connected to and pivotable about the first joint, a second joint connected to the first branch, a second branch connected to and pivotable about the second joint, a third joint connected to the second branch, and a third branch connected to and pivotable about the third joint. The third branch can have an attachment mechanism. The first joint is configured to drive movement of the arm through rotation of the first joint.
