BlueZero broken link

Hi,

The release notes of 3.5.0 mention BlueZero, but the link result in a 404:
https://github.com/blueworkforce/bluezero

I could not find a valid link using a web search either.

Does this product still exist, or is it not public/released yet?

Re: Distorted point cloud

I could finally figure out how to compute the point cloud correctly, without relying on internal knowledge of the simulator. I still have to understand some of the math (such as order of operations and how exactly each coordinate system relates to one another) to know where I went wrong before. Once...

Re: Distorted point cloud

Thanks a lot for your reply. Your code works, but I can't rely on the "magic" simGetObjectMatrix() in my real world robot. So I tried to adjust my code as close as possible to your approach, while only relying on angles of servo motors and the distance reading of my physical proximity sensor. I adju...

Distorted point cloud

Hello, I have a puzzling error when manually creating a point cloud, which causes it to be distorted. I made a 3D laser scanner in V-REP, using a proximity sensor that can rotate from left to right and from top to bottom. Sweeping over a certain range of two angles (phi and theta), I record the dist...

Re: Asti model - how does hybrid mode affect IK

Thanks, I understand now. So the foot position itself isn't really controlled, it is just an input for the IK engine that computes the joint positions assuming the foot can be freely positioned. When the joint positions are then indeed realized by the position controller, it does not care where the ...

Re: Confused about passive joint behavior

Uncheching "body is dynamic" for the neckJointSphere solves the problem, indeed: the head can be moved with the GUI slider when its neck joint is in passive mode. You just need to adjust the following code in the robot's child script: -simSetJointTargetPosition(neckJoints[1],minVal[3]+simGetUISlider...

Confused about passive joint behavior

Hello, I am trying to understand how to actuate joints and looked at the Asti model to experiment (I just placed it in an empty scene). After the simulation started, I selected the Asti robot and used the GUI sliders to adjust its 1st neck joint (called joint #0 in the robot model). Then I tried the...

Asti model - how does hybrid mode affect IK

Hello, I am wondering how the inverse kinematic mode (with hyprid operation checked) in the Asti robot works. When you put Asti in an empty scene, and remove the friction of the floor, the feet slide along the path defined at the feet (leftFootPath/rightFootPath) as you would expect: the feet move o...
