◆ ManipulationStationHardwareInterface() [3/3]

ManipulationStationHardwareInterface ( std::vector< std::string >  camera_names = {})

Subscribes to an incoming camera message on the channel DRAKE_RGBD_CAMERA_IMAGES_<camera_id> where camera_name contains the names/unique ids, typically serial numbers, and declares the output ports camera_s_rgb_image and camera_s_depth_image, where s is the camera name.

◆ Connect()

void Connect ( bool  wait_for_cameras = true)

Starts a thread to receive network messages, and blocks execution until the first messages have been received.
