Bostons Brick Closet posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingHello, This is my first MOC post here on Eurobricks so forgive me if I make newbee mistakes. Here's my fancy little diagram that's shows you how it works!! This is a an idea I am hoping to expand in the future to do some actually cool stuff ( : Firstly you need to enter the infomation you want to move the motor on the Raspberry Pi (the direction and the amount of degrees). Here is a little 3d render of it. The motor rotates the amount you specify and the color sensor on the right side senses if the Rasberry Pi's LED. For the instructions, more infomation and all of the things you need to set this up and build it for yourself come to my website: http://bostonsbrickcloset.blogspot.com/ Video: [media]http://www.youtube.com/watch?v=T85PzIO5GSk[/media] Not sure why the vid does not work ) : Links for the images: (for Creative Commons) https://commons.wikimedia.org/wiki/File:Lego-mindstorms-ev3.jpg https://en.wikipedia.org/wiki/File:Raspberry-Pi-3-Flat- Top.jpghttps://en.wikipedia.org/wiki/File:Raspberry_Pi_Logo.svg
technical posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI made a scanner from the printer I made earlier. I drew a test page and also scanned a print I made on the same frame from when it was a printer... re-digitized. It uses the color sensor. The digitized image is saved to the EV3 memory where I can download it on the computer as shown in the last image below. It's pretty crude but it's a good proof-of-concept I could improve on. Anybody else done this?
technicgear posted a topic in LEGO Technic, Mindstorms, Model Team and Scale ModelingI recorded this video as part of the tutorial I wrote about line following at http://thetechnicgea...ing-mindstorms/ I find it quite interesting the different behavior of the tuned and untuned PID Controller. This weekend I have tried building a robot with bigger wheels ( the one from 42007 Motorbike ) and it missed the line quite easily... because a little correction moved the robot too much but too small Kp make the robot lose the line easily. Any ideas about what can I do?
