Electronics / B-Robot EVO 2 Circuit Board Replacement
« Last post by shdo1937 on January 18, 2024, 09:40:22 AM »
Hello, I am working on constructing the B-Robot EVO 2, however, I can not find the control board they list: ... oard-v1-0/

I need a control board with the same capabilities to replace this one and move forward. Does anyone have any suggestions? Anything will help because I am new to this, thank you!

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!
