CoppeliaSim forums

Those are messages from the statusbar.

To show the console, there should be some "Show console" setting under Tools -> User Settings -> Various Settings.

Or you can simply launch CoppeliaSim from a command prompt to view loading messages.

Check the console output to see if there are some relevant messages.

You should see

[CoppeliaSim:loadinfo] plugin 'Joy': loading...
[CoppeliaSim:loadinfo] plugin 'Joy': load succeeded.

or otherwise a fail message.

Hello,

Position/distances are in meters.

You must have used a threaded script, which runs asynchronously. Use a non-threaded script, instead; in that case sysCall_sensing() is called exactly once per timestep. You can also achieve the same level of control in a threaded script by using sim.setThreadAutomaticSwitch() and sim.switchThread() ...

Hi, there's no such thing as the rotation range of an object. The rotation of an object can be expressed by a 3x3 orthonormal matrix, so the object can assume any rotation. On the other hand, you can parametrize such matrix in various ways (e.g. the various sets of Euler angles, unit quaternions, et...

No, the center of mass is a different property which you can read/modify with sim.getShapeInertia / sim.setShapeInertia . Even if an object does not have homogeneous density, its dynamical properties are entirely defined by the inertia tensor, mass and center of mass. sim.getObjectPosition returns t...

I think the only documentation of most robot models is their script itself :)

It is also a good learning exercise to read and understand the models' scripts.

ASTI's script works by defining paths (by Lua tables) and moving left/right foot IK target according to the defined path and timing law.

The manual can be found in the "helpFiles" directory of the release package.

The online manual refers to the latest released version (4.2.0 as today).

Each release comes with an offline manual which you can find in the "helpFiles" directory of the release. In the manual there is an Inverse Kinematics tutorial which is always updated for the features of the corresponding release. (the online version always refers to the latest released ve...

Yes.

sim.moveToPose does exactly that. It will linearly move an object with the specified velocity/acceleration/jerk limits, and it won't return until motion complete, so it must be used in a coroutine (threaded script for old CoppeliaSim versions).
