Daniel Richter, in charge of Hextronics' electrical-mechanical design and our manufacturing engineer, creates these testers to identify the best materials to use as well as areas in need of improvement. He designed a 3D-printed mechanism which bends different wires continuously to recognize the point of failure, as well as compare durability of alternate wires. The stress-tester simulates the life of a wire in the Universal and Atlas drone stations, constantly moving and bending. Each wire must provide the required current and sustain uninterrupted performance to ensure the drone station is always ready when necessary. There are countless wires incessantly operating in the drone stations, if just one wire were to fail the entire system would be ineffective in immediate response situations.
