Currently, the node is overwritten in a custom workspace (which will not be installable due to the fact that they are called the same) and therefore all the standard programs using this node don't work properly any more. The node would have to be renamed and only used when there are multiple robots in the simulation. Also some of the topics have a weird handling due to the fact that you have to have namespaces. This might be unintuitive for the students.\r\n\r\n@marc-hanheide maybe we can talk about this tomorrow at our meeting."}}
