bartneck Posted May 26, 2013 Posted May 26, 2013 I finnaly got the time to program my little EV3 R2-D2. The new "Move Sterring" block makes it super easy to create a proportional line follower. Still many loose ends in the latest builds, but I am certain they will all be tied up soon. I posted a screen shot of the software here. Have a look at the model at our upcoming LEGO show here in Christchurch: CBS2013. The biggest LEGO show in NZ ever. Quote
Doc_Brown Posted May 26, 2013 Posted May 26, 2013 That is awesome! I love the sounds. Very well done, I have no idea about programing, but seems really good! How did you get it already? I thought EV3 wasn't available till August? And is it only available thought Lego Education here in Aust and NZ? Quote
Someonenamedjon Posted May 27, 2013 Posted May 27, 2013 (edited) The line follower is very chunky, you should try to make it better by taking in ideals from other line followers, like this one: http://www.nxtprograms.com/line_follower/steps.html Edited May 27, 2013 by Someonenamedjon Quote
bartneck Posted May 27, 2013 Author Posted May 27, 2013 This line follower uses the new move steering block. That is why its performance is limited. But it is super easy to implement... Quote
Burf2000 Posted September 11, 2013 Posted September 11, 2013 OO I need to make one of these for a show, I will take a look! Quote
TasV Posted September 11, 2013 Posted September 11, 2013 This is pretty nice! I know you are using the new steering block, but if at some time you'd like to develop a PID controller check this out: http://www.inpharmix.com/jps/PID_Controller_For_Leg Quote
Jim Posted September 11, 2013 Posted September 11, 2013 You probably mean this link: http://www.inpharmix.com/jps/PID_Controller_For_Lego_Mindstorms_Robots.html Have been reading it as well. Awesome tutorial! Quote
TasV Posted September 11, 2013 Posted September 11, 2013 (edited) Yes... not sure what happened there??? I'm trying to convert it into RobotC as well and I'm kinda interested in going back and relearning calculus so I understand it a bit better... when I have the time... bring on the Christmas Holidays!

Jim Posted September 12, 2013 Posted September 12, 2013 I am going to implement the PID controller (most likely only PI) for rotating my robot, using a HiTechnic compass sensor. I will do this in EV3-G (don't even know the real name) and RobotC when it's released. Quote
