Electronics / Waving detection for Halloween animatronics
« Last post by perigalacticon on November 17, 2023, 03:25:24 PM »
I have several animatronic figures I use outdoors for Halloween.  They riun on Esp8266 microcontrollers and have mp3 players, addressable leds, and std cheap pir motion sensors and they work pretty well now.  I thought I would try to upgrade to some sort of gesture detection for next year.  I'd like to try to detect kids waving at the props, of course disregarding other motion.  I've done preliminary testing with digital lux sensors and ultrasonics, and so far the results aren't good enough.  With signal processing I thought I could detect waving motion in a sensor signal.  That's like a frequency of 2-4 Hz (cycle = back and forth).  Do you think there is a way to do this without resorting to machine vision?  The number and type of sensors available is bewildering.  This should be easy, right?
Hello! I'm new  to the society of robots forum. I am an undergraduate who is focusing on a tracked robot build as a project. However my background is not on engineering side but more of computing, but I am in charge of building the robot. Is there a place or sources that I could get information to build a tracked robot or the track system. I would be very grateful. I will be posting my journey of building the robot here and keep you guys updated!

Electronics / Re: Help with an old ATRV-mini
« Last post by migsdigs on July 19, 2023, 04:27:17 AM »
I have an iRobot ATRV here that we are looking to revive. I would imagine that the two robots have similar base components and both have rFlex boards for controlling motors, sensors... Did you manage to access the onboard computer from an external PC? or get it to work remotely And if so, how? Also, were you successful in replacing the original board with a new one? Right now I am only able to drive mine around using an old joystick, but we are looking to gain access to motor commands to control with a NUC or something similar.
Would appreciate any feedback you have :)
