Re: ROS Interface message type

That happens because the message you added depends on another message (actionlib_msgs/GoalID), which is not present in meta/messages.txt. Unfortunately the build system does not resolve those dependencies automatically: you have to list all the relevant messages.

Re: ROS Interface message type

if you are trying to do:

Code: Select all

pub = simROS.advertise('/my_topic/follow_joint_trajectory/goal', 'control_msgs/FollowJointTrajectoryActionGoal')
then the message you need to add in meta/messages.txt is:

Code: Select all

control_msgs/FollowJointTrajectoryActionGoal

Re: Building plugin fails in rev 4

This error is caused by using an obsolete version of Python. A fix for Python 2 has been pushed recently to libPlugin , however since Python 2.x has already reached end of life as beginning of year 2020, other packages will also stop supporting this obsolete version of Python, and you are likely to ...

Re: Nill Value Returning

You have a typo: retLengths vs. retLenghts (by the way, the first one has the correct spelling: length).

Re: how to run coppeliaSim remotely, ssh or xvfb or others

How do you mean remote computer control?

Can you start CoppeliaSim on the server and communicate via remote API?

Also, have you tried SSH with X11 forwarding (ssh -X ...)?

Re: B0 resolver could not be launched.

Hi,

could it be that your machine it is not reachable by its host name (御坂美琴) via the IP protocol?

Try executing the following

Code: Select all

set B0_HOST_ID=127.0.0.1
before running b0_resolver (replace 127.0.0.1 with your local IP address if you are using multiple machines).

Re: How to write script about Spring?

If the question is about how to make a spring: For a spring, you have Hook's law: F=k x where F is the force of a spring, k its constant, and x its displacement (or stretch/compression). In CoppeliaSim, set your joint (let's suppose it's a prismatic joint) into torque/force mode , the motor enabled ...

Re: simOMPL Optimal Path Planning Optimization Objective?

OMPL's optimization objectives are not currently supported. I can add support for simple (i.e. not-compound) optimization objectives, however it will not be possible to fully support the programming interface described here . If you have an idea of how the OMPL plugin Lua API for this aspect should ...

Re: How to make the quadricopter fly to a specified coordinate?

Then i try to set the position of the quadricopter's Quadricopter_target to the specified coordinate, but when simulation starts, Quadricopter_target's position restored. That's how it is meant to work: you set the target position by moving Quadricopter_target object. It should work also if setting...
