Re: Quadcopter model Dynamics

Hello,

for parameters to adjust on that model, have a look at the child script attached to the model, in the init section.
But keep in mind that this model is only meant as an example, and it probably makes sense to write your own controller depending on your application.

Cheers

Re: Grasp ball but always fall down

Hello, grasping is not an easy task. Make sure to have high friction parameters for the ball and the various gripper elements. Additionally, try to adjust some of the gripper parameters (e.g. max. force of the open/close joint openCloseJoint , or the target velocity). The problematic aspect of a bal...

Re: Python - Lua B0 server client

Hello Marco, I think the simplest and best approach would be to use the ZeroMQ-based remote API , since you are using Python. Then, you will also be able, in a very simple and straight forward way, to call script functions from Python, sending and fetching data to/from CoppeliaSim, with sim.callScri...

Re: Turn off "Simulation parameters" pop-up box

Hello, you can try to work with sim.setInt32Parameter and sim.intparam_simulation_warning_disabled_mask and/or sim.intparam_dynamic_warning_disabled_mask. Other than that, you can click through those dialogs 3 time, then re-use the generated system/settings.dat file, that contains that information. ...

Re: Pass values into child script in headless mode

Hello Kat,

yes, you can do this with named parameters and the command-line option -G, e.g.

Code: Select all

./coppeliaSim.sh -GmyValue=hello
Then you can retrieve the value with sim.getStringNamedParam / sim.getNamedStringParam

Re: How to get deviation for self balancing robot.

Hello, working with orientation can be tricky or difficult to wrap your head around. There are at least 3 ways you can understand an orientation: using quaternions: this is rather difficult to understand, but very convenient for calculations. e.g. sim.getObjectQuaternion using Euler angles: this is ...

Re: can I record video with vision sensors?

Yes,

simply read the image of a vision sensor (and then save it) in the sensing section of a non-threaded child script. This will produce one image in each simulation step.

Re: How to hide the robotic arm in the vision sensor

Hello, until CoppeliaSim V4.2.0, you can tag any object with a renderable flag . If the flag is on, then the object is visible from vision sensors. You can set that flag in the object common dialog . However, starting with CoppeliaSim V4.3.0, vision sensors will see almost the same objects as camera...

Re: Errors with B0 and ZeroMQ add-ons and remote api clients.

unfortunately I can't see anything suspect...

Is your installation fresh or modified somehow?
