Looking to paint the town red (or his buddies at any rate), Nathan Loden devised this simple device to detect if the paintballs are traveling at a safe speed (& 300 ft/sec). Consisting of sensor circuitry and a microcontroller with a three digit, seven segment display driver, it detects the presence or absence of a ball by measuring the amount of IR energy striking the sensor, causing a voltage swing detectable by the micro. A timer is set to overload if the number of instruction cycles exceeds a limit equal to 300 ft/sec, indicating safe shooting.
Are they robots or androids? We're not exactly sure. Each talking, gesturing Geminoid looks exactly like a real individual, starting with their creator, professor Hiroshi Ishiguro of Osaka University in Japan.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
