It provides a complete development environment to model, program and simulate robots.

From a terminal, go to the folder containing your controller program and start it with gdb: gdb mycontroller. Webots is an open source and multi-platform desktop application used to simulate robots. System : Microsoft Windows 10 Famille Process ID : 8892 Processor ID : x86 Family 6 Model 60 Stepping 3. Now we are going to modify the world and decrease the step of the physics. I've included line numbers as comments for some of the lines at which breakpoints might be placed. Although Webots is still active, the simulation blocks because it waits for data from the terminated controller. The simulation may be paused, run step-by-step, in real time or in fast modes. I'll use the example program below to demonstrate some debugging techniques in addition to showing some of the challenges that might be encountered when debugging lambda expressions. The example below shows some simple captures in a few of its lambda expressions. This is due to the fact that a C++ lambda expression provides a way to capture in-scope variables which may be later used when the lambda expression is executed. In the dialog choose the M圜ontroller.exewebots process. Then, in Visual Studio, use the Debug / Attach to Process. Proceed like this: In Webots, hit the Pause button then the Reload button.

Using a lambda expression often makes writing a callback function significantly easier since various pieces of state that are known in the function from which the callback is passed don't need to be packaged up into a data structure which the callback function will later access. If you want to debug your controller with Visual Studio you can attach the debugger to the running controller process. Lambda expressions are often used in situations where a callback function is desired. What is a lambda expression?Ī lambda expression provides the C++ programmer with a way to create an anonymous or unnamed function. Even if you're not interested in debugging lambdas, the techniques presented here are useful for many other debugging situations. This article shows how you can debug lambda expressions using GDB, the GNU Project Debugger. Modern versions of the C++ programming language have a feature known as lambda expressions.
