Re: Trouble using sim.rmlMoveToJointPositions

Hi, Thank you for your Reply!


I have noticed that in the example you gave me the object contains only one joint. However, i am trying to use this function with a kuka LBR iiwa, and the movement is not realistic. Do you have an example of this function being used with a more complex model?

Thanks!

Trouble using sim.rmlMoveToJointPositions

Hi, my robot is behaving weirdly when i try using sim.rmlMoveToJointPositions and i am not sure why.

Here is my scene:

Re: OMPL Plugin crashes ROS interface

Actually, with further testing (i'm not using OMPL anymore) the communication continues to crash. I've looked in the code a bit, and the problem seems to be with the simSetJointTargetPosition() function. Here is a drive link to my project with all required files, please look first at the READ ME.txt...

ik calculation weight

Hello everyone, I am trying to solve the inverse kinematics of my redundant robot and since some configurations are better than others, use different ik calculation weight parameters for each joint. However, changing the weight values is not having any difference at all. For example, a weight of 0.0...

OMPL Plugin crashes ROS interface

Hello, I was trying to use OMPL toguether with Ros Interface. However, when the OMPL tries to find a solution to RRT Connect and is unable to, communication to ros interface crashes and i am unable to communicate any further to ROS. Do you suggest any alternatives so I am able to keep using Motion P...

Motion Planning with non-threaded child scripts

Hello, I have implemented a motion planning algorithm in a non-threaded child script of my robot. However, I am using simSetJointTargetPosition to move through each point of my path and the robot is not being able perform nicely this way. In other words, is there a way for me to obtain a smoother mo...

Re: A Few questions about Inverse Kinematics

Thank you for the reply!

About the last question, I was wondering if there is a way for me to directly obtain a solution for the ik with the given constraints, instead of try and error with the simGetConfigForTipPose().

A Few questions about Inverse Kinematics

Hello! I am trying to simulate a scene with a Sawyer on top of a OmniPlataform and I having a few problems with the inverse kinematics solver. Basically, there are 3 questions I have about the issue. 1) The Sawyer's arm weight is influencing my results, as the solution the ik solver gives me is alwa...

Sending Images to Ros rotates it 180°

Hello, I am using Ros indigo to send commands to vrep and to receive a few images from the vision sensors. Howewer, my images are rotated 180°. Is there a way I can fix this?

Sending Images to Ros

Hello all, I am trying to simulate a Sawyer robot using the RosInterface. However I am facing a problem when I try to send the Image of the Head Camera to Ros through the simExtRosInterface_publish command. The type of message I am trying to send is a 'sensor_msgs/Image' type and according to the Ro...
