All they do is dispatch motor:command events which are translated into motor:control events (with smoothing, etc). #rhrt: 11/10/08 20:40 I was actually going to trash the Motor objects in favor of a system that controlled the vector of the robot as a whole. #rhrt: 11/10/08 20:40 i like that idea, but I think it needs to be build outside the motor controllers #rhrt: 11/10/08 20:40 tommost++ #rhrt: 11/10/08 20:40 i.e. in the path planning part of the code #rhrt: 11/10/08 20:41 I put my planned (but still malleable) API here: https://www.rhitrobotics.org/browser/trunk/software/rb/motor/hilevel.py?rev=280#L34 #rhrt: 11/10/08 20:41 that would probably need to take into consideration things like the compass and such #rhrt: 11/10/08 20:42 This one is supposed to be low-level, just to do tweening. #rhrt: 11/10/08 20:42 which one? #rhrt: 11/10/08 20:42 the direction one? #rhrt: 11/10/08 20:42 move(), the one I liked to. It accepts coordinates relative to the current position, so the controller should be the one monitoring the compass. #rhrt: 11/10/08 20:43 I was thinking that it would have a target vector, and monitor the actual vector, and pass appropriate arguments to this function. #rhrt: 11/10/08 20:43 i'm so confused #rhrt: 11/10/08 20:44 i don't see any reason for that to be included with the motor controller code, it seems much more path planning ish #rhrt: 11/10/08 20:44 Oh, sure. #rhrt: 11/10/08 20:44 also, two_pi makes me want to shoot you #rhrt: 11/10/08 20:45 What about pi_3o2? ;) #rhrt: 11/10/08 20:46 auchter: You should check out the GUI. It's really entertaining to watch the little blue dot squiggle around. #rhrt: 11/10/08 20:46 i've got two exams to fail this week yet (oh, three more next week), so i'll look at it tomorrow. #rhrt: 11/10/08 20:47 Good plan.

#rhrt: 11/12/08 21:20 Um, yeah, I wanted a simulator gui that would chart the progress of the robot as it moved around virtually. #rhrt: 11/12/08 21:20 So you could mock that up. #rhrt: 11/12/08 21:20 Or you could work on backend stuff for that. #rhrt: 11/12/08 21:20 As in showed it inside the course editor? #rhrt: 11/12/08 21:21 ok, i was wondering if/how we should integrate the current GUI (manual control) with the map editor? #rhrt: 11/12/08 21:22 I wasn't thinking that they'd be the same program. #rhrt: 11/12/08 21:23 The map editor was intended to be standalone and ultra simple. #rhrt: 11/12/08 21:23 why? #rhrt: 11/12/08 21:23 Why should it be integrated? #rhrt: 11/12/08 21:23 It does something completely different. #rhrt: 11/12/08 21:24 It shouldn't even have the event handling stuff. #rhrt: 11/12/08 21:24 It just writes files of latitude/longitude points. #rhrt: 11/12/08 21:24 yea, i agree that's it's very different #rhrt: 11/12/08 21:24 There's a rather comprehensive spec on the wiki. #rhrt: 11/12/08 21:24 You could argue for integrating it with the simulator, I suppose. #rhrt: 11/12/08 21:24 it seems like it could be nice to have one place to go for all the GUI stuff though, instead of having to remember a bunch of different programs #rhrt: 11/12/08 21:25 Then you could permit editing of the map inside the simulator. #rhrt: 11/12/08 21:25 That makes sense. #rhrt: 11/12/08 21:25 Yeah. #rhrt: 11/12/08 21:25 i'm not sure how the widget layout would work though.. #rhrt: 11/12/08 21:26 so the simulator " that would chart the progress of the robot as it moved around virtually" would be a 3rd program? or added to course editor #rhrt: 11/12/08 21:27 i don't think we really need 3d simulation #rhrt: 11/12/08 21:27 No, it would just be a 2d map. #rhrt: 11/12/08 21:27 The robot would be a box moving around on it. #rhrt: 11/12/08 21:27 i know. i meant 3rd program, as in completely seperate #rhrt: 11/12/08 21:28 And it would dispatch "obstacle found" events as the robot approaches obstacles. #rhrt: 11/12/08 21:28 ah, i totally read that wrong :) #rhrt: 11/12/08 21:29 ha yeah, i figured that. ok so that's a yes, a separate program, not integrated with course editor? #rhrt: 11/12/08 21:29 but then if it has to read obstacles.. that'd be lots of overlap #rhrt: 11/12/08 21:30 for the code, we could always make a library that is used by both #rhrt: 11/12/08 21:30 i'm still trying to think about how we want the GUI working.. #rhrt: 11/12/08 21:30 No, you can totally integrate it with the course editor if you like. #rhrt: 11/12/08 21:31 I simply wanted to start with the course editor, initially, as a simple project to get people started. #rhrt: 11/12/08 21:31 ok #rhrt: 11/12/08 21:31 It wasn't supposed to take all quarter. :-/ #rhrt: 11/12/08 21:31 eh, things happen #rhrt: 11/12/08 21:31 yes understood. i would agree a single course/simulation program in the end #rhrt: 11/12/08 21:38 Ching-Chen is coming now. #rhrt: 11/12/08 21:39 Apparently he was asleep. #rhrt: 11/12/08 21:39 how do you know?
