Thank you for the answer. Now it is working properly. Last question, is it possible with simIM to draw shapes with filled color?

drawing rectangle or circle on image obtained from vision sensor

I'm using CoppeliaSim 4.5.1 in Ubuntu 18.04 LTS. My goal is to draw a primitive shape (e.g. rectangle or circle) on the image obtained by vision sensor. The scenes shipped with CoppleliaSim aren't straightforward enough for my purpose. In addition, I would like to switch between two colors (i.e. red...

What is the correct way to read applied external force on a tool?

I have seen three ways to get force measurements applied on a tool attached to a joint. Force/Torque sensors Contact info between two objects sim.getJointForce. The first one requires compensating for the weight of the tool. For kinematic-based control which usually a velocity-based control scheme i...

Re: CoppeliaSim for Surface cleaning

Hello, not sure if I understand exactly what you mean... but why not give the tool a friction of zero? Cheers In this case, what is the exact parameter I need to change? The tool now is the capsule from Add->Primitive shape. I'm using Bullet now. Do I need to change this "friction": 0.5, ...

CoppeliaSim for Surface cleaning

For cleaning purposes, I need to attach a tool to the end-effector. As a result, two objects have made contact with each other. I would like to reduce the friction between only two surfaces so that the contact should be as slippery as possible. Is this kind of simulation possible in CoppeliaSim, if ...

callScriptFunction and jsoncons for passing array

It seems there is a change from CoppeliaSim in the way sending and receiving an array of parameters. I need to send and receive a bunch of values between C++ client and and CoppeliaSim. My old code in CoppeliaSim 4.5 no longer works in version 4.6. In Lua, I have these functions function get_q() loc...

Aerial Manipulator suggestion

Are there any good aerial manipulators that accept velocities as control inputs in CoppeliaSim? Due to time and stability concerns, I don't want to create my own. Models that are commercially available are welcome but I prefer free ones.

Painting the robot's trace

I'm using ZeroMQ, C++ and CoppeliaSim 4.5.1 in Linux. I would like to draw the robot's path (i.e. the base's position and the end-effector's position of the arm). I need to send the actual data from my client since it has the controller. I'm looking for the most efficient way to do it. I just need s...
