Re: fast Hokuyo laser scan data with ROS

Thank you so much for your advises! I was so confused about the "range" element but things are clearer now.
It didn't occur to me to use the Hokuyo sensor with well implemented code for ROS. Now I'm using it and I've succeeded sending the laser data to Rviz.

Thank a million, friend!

Re: fast Hokuyo laser scan data with ROS

I use the array of data from the sensor, "measuredData" , as already implemented in the Hokuyo sensor child script and then pass that data directly into the function for sending to ROS as seen on the previous function code. This is the portion of code information from CoppeliaSim -- measuredData now...

fast Hokuyo laser scan data with ROS

Hi I'm trying to send the laser scan data from Hokuyo_URG_04LX on CoppeliaSim to ROS but so far I can't figure out how to make it work correctly. I could send the transform from laser_frame to world_frame and tested to see it works correctly on rviz. I created a topic with message, sensor_msgs/Laser...

Re: Closed link Mechanism constrained by springs

Oh thank you Coppelia, this really give me new insights. I didn't really pay much attention to the mass or moment of inertia of each shapes when I grouped them together. I will reconstruct the mechanism again this time with attention to each shape and the constraining.

Thank you.

Closed link Mechanism constrained by springs

Hello everyone I am trying to build a simple mechanism that consists of parallel link closed by two plates, the bottom plate and the top. On either sides of the mechanism, a spring is used to constraint the structure and give it damping property. Two motors on top will pull on the springs to control...
