Re: How to install vrep version 3.5 in ubuntu 14.04 LTS?

In a first step, try to simply run V-REP naked (no plugins or other optional things). This means, at first, you do not need the dynamics plugins nor the mesh calculation plugin. When you compile V-REP source code, you obtain a library (v_rep.dll or similar). That one is loaded by the client applicat...

Re: Consider point cloud in path planning

Hello, following is probably happening: a point cloud only contains points. A shape object, only contains surfaces (i.e. no volumes). You can't check for collision between a point and a surface. You have two options: use an octree instead of your point cloud use an octree instead of your shape(s). C...

Re: How can i get RSS data from wireless network

Hello,

for a real wireless signal, you can't. Unless you write a plugin for that.
On the other hand. the simulated wireless emitter/receiver is just simulated, and the signal strength is either 1 or 0.

Re: Use UI to initialize simulation

Hello, you cannot block your non-threaded child script. Otherwise everything will freeze. Your best option is to use a customization script that provides the dialog. Once the user makes a choice, you can have the customization script launch the executable, and start the simulation with sim.startSimu...

Re: Sensing if a light sensor is within a cone of light

You understood me wrong: you need to check first if your data you read is old data from your previous application. If it is old data, then simply pretend it is an empty table. If the data is new, then you need to unpack it. The simplest test whether you have old data or new data stored would be to c...
