For one of our customers, manufacturing Tea & Coffee vending machines, we developed completely automated testing of all the operations using robot, sensors, valves, microcontrollers. It can perform all the 70+ steps, earlier performed by human operator accurately, fast and records the results of all the tests into a web server from where we can see the success or failure of the machine, before it goes to their customer. It can press all the buttons using a robot, measures parameters like temperature, selected motor (for tea / coffee / water) , rotation angle (clockwise / anti clockwise), weight of filled cup (90gm for full cup / 45gm for half cup), message on the screen using respective sensors and validates expected outcome. It repeats for 5 times for consistency for every machine and then declares if the machine has passed all the tests and is good for dispatch. If any of the verification is failed, it shows error and writes in the server database and rejects the machine along with type of error for R&D to fix it. This process saves lot of time and testing manually, eliminates all human errors, and records all the test results in the server which can be accessed over internet.
