Delta robots like this automated phone tester are awesome: high speed, accuracy, and mesmerizing to watch. [Justin Engler], a security researcher from ISEC Partners (also speaks at DEFCON on occasion) needed a robot to help with repetitive testing. He contacted the folks over at Marginally Clever to see if they could help him out, and they came up with this slick delta robot.
Normally they build these robots out of plywood, but [Justin] requested a bit more of a modern look, and although it looks blue, it’s actually clear acrylic: they haven’t removed the protective film yet. The robot is quite functional, but [Justin] plans on upgrading it in the future to increase the top speed. It currently has a built-in camera, using OpenCV to watch the log-in screen as it tries every combination as quickly as possible.
