Re: Error Building KheperaIV-SLAM

You need to contact the authors of that repository, they probably haven't updated their CMake configuration in a couple of years.

Re: Open Source implemented examples on Argos

The ARGoS examples provide all of the things you ask. Check the foraging example for an FSM and the flocking example for physics-based methods.

Re: An infinite continuous (borderless)arena

It's not possible just out-of-the-box, unfortunately. The issue is that typical physics engines assume no border and no wrapping. The physics engine you need should be fixed to allow for wrapping, which would also impact the way collisions are handled. Chipmunk and Bullet, the engines we have at the...

Re: Stop the experiment by lua code

You do it in the loop functions, not in the robot controller. You reimplement the loop function method "IsExperimentFinished()", as shown in the embedding examples. No robot can single-handedly stop the simulation.

Re: Clarification on the operation of the ambient light sensor and distance from it

In your code, the use of print is not correct. It seems to print a double using the format for an int.

Also the return statement in the same function contains a redundant assignment.

Re: Clarification on the operation of the ambient light sensor and distance from it

Did you notice the position of the light sensor on the kilobot,, and how that affects the calculation of the readings? Also the position of your light is at height zero, which is unusual.

Re: Clarification on the operation of the ambient light sensor and distance from it

The answer to all of your questions are in the original Kilobot paper and in the source code. I encourage you read both, they should make everything clear. what is the unit of measurement of the value specified in the <light> tag in the intensity attribute? It's an intensity multiplier. See this cod...

Re: Error while initializing light entity

You found a bug, but fortunately there's a workaround. When you initialize the LED medium, try this: <led id="leds" grid_size="2, 2, 2" /> Essentially, what is happening is that the grid size to store the LED entities is calculated as 0 because your environment is smaller than 1m x 1m. It's a bug, y...
