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?

Hi there wonderful roboticists!

Hi,
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

Hi everyone,

If we start about robot project, what is the cost an average ?

Thank you so much

Hi everyone,

If i want built a robot in freelance, can i do it or i follow videos on youtube to be good ?

Thank you for your answer
