OpenDRis a European research project developing a toolkit for core robotic functionalities based on deep learning. Cyberbotics provides its simulation expertize and demonstrates the deep learning toolkit capabilities on the web.

The driving platform was developed by Cyberbotics on behalf of Renault group to study human driver reactions to an advanced text-to-speech guiding system in a large city, using a VR interface.

CoppeliaSim is used for fast algorithm development, factory automation simulations, fast prototyping and verification, robotics related education, remote monitoring, safety double-checking, as digital twin, and much more.

5 physics engines (MuJoCo, Bullet Physics, ODE, Newton and Vortex Dynamics) for fast and customizable dynamics calculations, to simulate real-world physics and object interactions (collision response, grasping, soft bodies, strings, ropes, cloths, etc.).

Powerful, realistic and exact volumetric proximity sensor simulation: performs an exact minimum distance calculation within a customizable detection volume. Operates on meshes, octrees and point clouds. Simulation of vision sensors with many image processing options, fully customizable and extendable (e.g. via plugin).

This video shows how a CoppeliaSim simulation model can easily be transformed into an efficient convex or convex-decomposed representation. Convex and convex-decomposed meshes are handled in a much more efficient way by physics engines.

This video shows how two (or more) robots can perform a complex inverse kinematics task, collaboratively, i.e. where the two tasks are inter-dependent). CoppeliaSim offers a powerful kinematics calculation module, that supports IK and FK also for branched/looped mechanisms, Jacobian visualization and callbacks, null space projection support, various constraints and solvers, joint dependencies, etc.

This video shows how a kinematics task (forward or inverse kinematics) can visually be debugged in CoppeliaSim. An overlay drawing indicates the state of the kinematic world, while the corresponding Jacobians are displayed in dialogs.

"I am testing you simulation tool in complex industrial automation and it has proven very capable... it has been an essential tool for the research and ideation process. It allowed us to prototype and study kinematics dynamics singularity workspace etc far better then any real prototype could"

With integration into the broader AWS ecosystem, RoboMaker offers unmatched flexibility, enabling developers to simulate various scenarios efficiently and deploy their applications seamlessly to physical robots.

A robotics simulator is a simulator used to create an application for a physical robot without depending on the physical machine, thus saving cost and time. In some case, such applications can be transferred onto a physical robot (or rebuilt) without modification.

The term robotics simulator can refer to several different robotics simulation applications. For example, in mobile robotics applications, behavior-based robotics simulators allow users to create simple worlds of rigid objects and light sources and to program robots to interact with these worlds. Behavior-based simulation allows for actions that are more biotic in nature when compared to simulators that are more binary, or computational. Also, behavior-based simulators may learn from mistakes and can demonstrate the anthropomorphic quality of tenacity.

One of the most popular applications for robotics simulators is for 3D modeling and rendering of a robot and its environment. This type of robotics software has a simulator that is a virtual robot, which can emulate the motion of a physical robot in a real work envelope. Some robotics simulators use a physics engine for more realistic motion generation of the robot. The use of a robotics simulator to develop a robotics control program is highly recommended regardless of whether a physical robot is available or not. The simulator allows for robotics programs to be conveniently written and debugged off-line with the final version of the program tested on a physical robot. This applies mainly to industrial robotic applications, since the success of off-line programming depends on how similar the physical environment of a robot is to a simulated environment.

Among the newest technologies available today for programming are those which use a virtual simulation. Simulations with the use of virtual models of the working environment and the robots themselves can offer advantages to both the company and programmer. By using a simulation, costs are reduced, and robots can be programmed off-line which eliminates any down-time for an assembly line. Robot actions and assembly parts can be visualized in a three-dimensional virtual environment months before prototypes are even produced. Writing code for a simulation is also easier than writing code for a physical robot. While the move toward virtual simulations for programming robots is a step forward in user interface design, many such applications are only in their infancy.

And then I followed as instructed and run the install.sh. Then, the catastrophe started. The install shell started removing pretty much ALL of my packages and software in my PC! I immediately stop the shell and hope to save some but it was already way to late. For comparison, it removed all my ROS installations as well as a few more third party installations on my PC. I have the log file which I goes I cannot attach here but I am very much willing to share with any technical support.

This command would remove EVERYTHING without asking to the user, without giving any warning! It simply accepts everything with -y option if the installation requires sudo apt remove --purge application. I honestly believe that if ANYTHING which needs to be removed or version changed, it should be WARNED.

Workaround: Use my modified script

Script downloaded from link above already has the fix applied, otherwise you will need to modify it, see: Fix bug in ifconfig parsing ljden/URSim_Install_Guides@ae6c220 GitHub

NB: You will need to ensure the net-statistics script has the right network device (see repo for more details)

And then run the modified install.sh script. Looks okay for now but I got the warning The following packages were automatically installed and are no longer required: libcurl4:i386 libnghttp2-14:i386 libpsl5:i386 librtmp1:i386 so I suppose a sudo apt autoremove at some point may cause problems with the ROS and other software again. I disregarded the no longer required warning for these specific packages just as a patch solution but probably not the best.

I also faced the same issue. Fortunately, I tried it on a disposable VM image hence the damage was not severe for me. However, what followed after that consumed my two months. Because of this issue, I was made to believe that there is no way to install URSim in Ubuntu 18 or 16. I am mainly working with the UR ROS drivers which are only supported for the higher Ubuntu versions. Hence to use UR ROS drivers with the URSim simulator, I had to use at least one VM, even if I am on a native Ubuntu 18.04.

The issue I faced was related to the latency of the communication between the URSim VM and the ROS drivers. I managed to make them talk with each other but soon after that the ROS driver started complaining about missing data packets. I tried many suggestions to resolve the error but none worked.

Finally, I started looking at the install script for the URSim and figured out that it removes all other installed packages. It is a sincere request to UR developers to give some attention to the simulator workflow too. With more and more third-party partners coming up with applications/products / Softwares, the URSim is the key functionality to make the development cycle efficient.

I have installed Android Studio and the Pepper SDK, and I'm able to boot up the tablet emulator and instal applications and run them using the Pepper API. When I start the emulator, the Starting Emulator screen stays at 34%, and the Robot Viewer does not show up.

I've tried connecting to the robot viewer, but I get an error about changing my IP address. I've tried 127.0.0.2, 10.0.0.5, and even connected to the tablet shell and found the eth0 address; however, I'm still unable to connect the tablet emulator to the robot viewer. Also, the tablet emulator does not connect to WiFi.

If it does not work on your platform, you can use a normal Android emulator, running an Android API 23. I usually use the 4" WVGA (Nexus S) device to get a similar screen size and resolution. The main difference is that you will not be able to get the focus.
