A robot arm that recognizes your face — April 29th, 2026 The earliest commercial robots, like those used in factories for assembly, weren’t intelligent at all — they simply moved motors in sequence according to pre-programmed commands. But today we can build sophisticated robots that respond to their environment and even people. More importantly, that is possible on a modest budget with off-the-shelf parts. Luca Di Lorenzo (AKA LucaDilo) proved that by using an  Arduino® UNO™ Q to create a robot arm that detects faces and acts accordingly. In this case, the robot a r m reacts to seeing a person’s face by picking up a pen and handing it to them. That is only moderately useful, but it is really just a demonstration of the hardware and capability. It shows that the robot can see what is around it and act accordingly.  LucaDilo was able to achieve that with very affordable and accessible hardware, starting with an UNO Q.…
