Swarm Robotics For Disaster Mitigation

Here's my final year project's simulation video using V-REP software! Title: Design and Demonstration of Swarm Robotics For Disaster Mitigation Using Robotic Simulator Software. The video shows my quadcopter with self-designed body and balancing algorithm. The single unit was then made into 4 more a...

External USB controller

I am planning to use an external USB controller to move an object's position in the scene. Currently I'm using the keyboard arrow keys instead. How do I retrieve the external USB controller's buttons into the script?

Low lFPS Simulation

Hi, My current simulation FPS is quite low, 15FPS average. I know that the imported meshes should be modified to have less number of triangles. But for the moment, can I reduce the "graphics" quality of the surroundings? Here's a picture showing my simulation. Are there any other ways to i...

Vision Sensor - Detection Environment

Hi,

I have a vision sensor that's set to render a specific colour. However, once I've added the Terrain model into the scene, it detects the Terrain too. I'm trying to prevent the Terrain from being rendered but visible in the vision camera at the same time. How do I set it to do so?

Thanks,
Danny

Mathematical Function to PID controller

Hi, I've implemented a mathematical function that balances an object in the translational axis. Normally a PID would contain the 3 K values for adjusting, but my mathematical function contains different input parameter and one output where I'll have to change the constants in order to adjust. What's...

Re: Vision Sensor - Spherical or Revolute Joint

Hello Danny, you can of course also use a spherical joint, but be aware that you can't control your spherical joint dynamically (i.e. it will act as a non-actuated joint). But in the end, using two revolute joints, as is done in reality, is probably the better option. Cheers I see, ok then I'll use...

Vision Sensor - Spherical or Revolute Joint

Hi,

I'm currently learning from a tutorial on vision servoing. The vision sensor will move based on its detection on a certain blob. A Yaw and Pitch revolute joint was used to tilt the sensor. But what if I choose to use a spherical joint?Since it covers all sections of an area sweep.

Regards,
Danny

Re: Changed Object Axis (Solidworks to VREP)

Hello, your STL file (and most mesh file formats) does not contain any information about reference frames for the exported shapes. It just contains vertices and indices. In any case, during import, V-REP will try to find a bounding box for each shape, that minimizes the volume of the bounding box. ...

Changed Object Axis (Solidworks to VREP)

Hi, I'm trying to import a shape made from Solidworks to VREP. The drawing's axis changed when it's in VREP. Here's my STL file: http://www.filedropper.com/quadmodel2 Below shows the Solidwork's axis reference. Once imported, the axis of my drawing changed. What might be the problem? http://www.file...

Quadcopter Path Planning

Hi, I'm trying to simulate a Search-And-Rescue for my self-made quad human detection: I'm not sure to which method is the most flexible approach between these 2: 1) To pre-set a path plan towards a target(human,for my case) and let the other Quads converge to the detected target 2) To program the vi...
