created new workspace; created launchfile; only webcam has to be started manuall, it does not start with launchfile; for gscam we only have to login on the robot laptop, than it worcs over ssh; I installed all packages on leatherback..... it was .....; I worte a node sc_scanner which consumes fidutial scans from the webcam and publishes Scan_Item or Scan_User messages, depending on the fidutial number; I started with the implementation of the main. I Used the lab_9 scipt for the start, than I realized that it does not use the leg detection. But the login works. My idea was to acrivate the laserscan when the user logged in and deactivate it again when the user logs out such that the robot not follows; I go home now....
