Jim, I just found out that my customer is not using a USB adaptor, just a serial com port. Any suggestions? Thanks Peter ... -- Peter Grey Sigma Delta...
Hi Peter, Yes, I've had problems with that one too:) It may be that their PC can't recognize the Port Number. Especially if they're using an after market...
Hi Jim, My program connects to a data logger to either upload time and date or download data to the PC. The first task is to give it the port number and then...
The TangentBug algorithm was developed by Kamon, Rivlin and Rimon .TangentBug uses distance sensors to build a graph of the robot's immediate surroundings and...
That is really funny. I remember discussing the method in 1994 at the University of East London. It seemed so trivial to me that it wasn't worth writing up. Ah...
sorry, actually I'm quite new in programming. The correct link is at http://kadiruyanik.files.wordpress.com/2011/03/tba2.pdf . Sorry for broken link....
Have you worked through the RobotBasic videos, especially part 1 and part 2? Get there by the youtube link from Robotbasic.org Can you program the robotbasic...
The object is discontinuous when the distance jumps from one range to another. You need to decide on a threshold. The rest is just geometry surely. So where...
Make it up. Nothing is written in stone. Personally I think Choset and others have made a meal out of a pretty trivial idea. In the papers what are the...
why do you blame Choset? The idea was from I. Kamon, E. Rimon, and E. Rivlin. Actually I cannot translate what I understood in the paper into RobotBasic...
Unless you want to mathematically prove that the resultant path is optimum or convergent or something why are you interested in the tangent at 1 pixel...
Thanks you for the informations. Actually I have created a new algorithm on path planning and I want to compare the algorithm with Tangent Bug. I have...
Using robotbasic with a usbmicro u451. Program runs fine while in editor but when saved as an .exe it works if the unit is plugged in. The program is to throw...
There was some discussion about this a few months ago. I do not believe an answer was given. You may wish to check older emails - if they exist? Good luck ...
Regarding the question of multiple serial ports, urrently you can only have ONE serial port open at a time - although the next version may support mulitiple...
Hi, I am making a screen containing some edit boxes a graph and some buttons. For detection of edit and/or button activity, I am trying to use interrupt. The...
I see some gosubs are used. If you do a non-gosub handler from inside a gosub routine, and the handler is supposed to change a global variable, does it in fact...
Thank you for your answer! I have used only gosub handlers and gosub subroutines, - and now even tried an array variable for storing data inside the gosub...
Rolf: I haven't tried any of this yet. But this section of the manual is suspicious: Also is (should be if?) you do need to change variables that are shared...
Thanks again! .. The first thing I tried, was in fact to try AllowEvents off/on, as I regarded it is some kind of global interrupt disable. While 'OnAction...
Hello, I have enjoyed doing some RBprogramming, but every now and then, this crazy problem pops up: In a program that I have run many times before, I am...
Hi RolfI, I may be missing something, but it looks like you are using a *goto *when you should be using a *gosub*. I believe you should *never* use *goto *to ...
Jim is absolutely right. Anytime you get the variable not initialized error it means you are using a variable BEFORE it has been set to a value. This is...
If you are having questions about global variables and how to use them I have a suggestion. Go to RobotBASIC.com and choose the FAQ tab. Scroll down to...
It seems a number of people might be having trouble with global vs local variables. We have a paper on our web page that answers the questions you seem to be...
Hi Jim! Oh, sorry, - what a misprint ... of course I am using gosub .... The program has grown and is now 700lines or so, a LOT less if the comments are left...
