RVIZ Point Cloud Representation of Grasped Objects

Hello all,

I am trying to perform point cloud reconstruction of objects grasped by a robotic hand using rviz. The hand is equipped with tactile sensors whose data are streamed through ros topics. I was thinking about identifying a point of contact once one of the tactile sensors gives a reading and storing this point until a point cloud is formed which can be used to reconstruct the object at hand. I am new to this, so any guidance about how to do it or any recommended other approach to follow to accomplish what I need would be much appretiated. Thanks!

Hi @aaa

There are multiple ways to achieve this. Since you are looking a starting point with RViZ I suggest you look how this is done with Tiago robot and adapt it from there:

Hope this helps

Does Tiago have pressure sensors in its grippers? Does it use that data to construct a pointcloud?

No it doesn’t but it will help him with the 3D reconstruction of point clouds
