mistlab / buzzkh4 Goto Github PK

When trying to run testbuzzexperiment.argos for khepera iv i get: "Robot is not ready to execute Buzz script."

Any idea why? Thank you in advance!

PD: this of course after installing khepera iv plugin for argos3 and BuzzKH4.

Two months ago i did install BuzzKH4 on my Mac with Ubuntu on VirtualBox. As long as I remember everything went ok.

Now I'm trying to install it directly on an Ubuntu work station but get this error message:

$ cmake -DCMAKE_TOOLCHAIN_FILE=cmake/TargetKheperaIV.cmake ../src/

CMake Warning (dev) in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as

project(ProjectName)

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

CMake Error: CMake was unable to find a build program corresponding to "Unix Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
-- Configuring incomplete, errors occurred!
See also "/home/acalderon/Descargas/BuzzKH4/build/CMakeFiles/CMakeOutput.log".

And I did verify cmake version with $ cmake --version obtaining:

cmake version 3.16.3

I found that cmake version on my Mac is 3.10.2, could this be the reason for the error I'm getting now? In such case, how should install procedure be updated?

Hello, I'm trying to use neighbors.broadcast to send a float number but the message is discarded for its size. I don't understand why:

1. the message id is just one character, which I suppose equals one byte
2. i suppose the float number is just 4 bytes
3. I don't know how much the sender id might be, but 2 bytes seems to me more than enough for names like k0, k1, k2...(as I've specified on argos file)

thus, the message is no more than 7 bytes, so I don't understand why the LogErr shows the following message:
[k?] Discarded oversize message (16 bytes). Max size is 8 bytes.

Thank you in advance for any help, cheers!

Acording to "gotop(ls,as) sets the speed of the center of mass of the robot. The speed is expressed as a vector in polar coordinates, where ls is the linear speed (i.e., the forward speed, in cm/sec) and as is the angular speed (i.e., in rad/sec)." I am expecting that: gotop(0.0, 3.1415926535/4.0) would make the Khepera IV on Argos3 rotate 45 degrees per step. Thus it needs 7 steps to be at 305 degree orientation, but it doesn't rotates at all, at the end of 7 steps (1 step = 1 second) the Khepera IV never rotated and it is still pointing to 0 degree, its initial orientation. How should I interpret this? Thank you in advance,
