Hi, We're participating in a project regarding in hand manipulation. For this project we need to store relatively large quantities of data we get from different sensors (including tactile sensors / position sensors / orientation / ...) to caracterize different objects. We then need to access those data to compare against incoming values. Is there a ROS package which already does this kind of storage / access ?
