Abstract (en)
[origin: WO9601978A1] A remotely operated device by which a single user can perform measurement or levelling tasks comprises an automatically levelling laser beam emitting unit (53) that can be remotely manoeuvred. The laser unit (53) is mounted in a body (50) which is mounted on a rotating base (53). A remote control means transmits signals to a manoeuvring means (21, 60, 61, 62) that controls the rotation of the base (52). A user sets up the device in a central location and moves to a location which must be measured. Using the remote control the laser beam is manoeuvred until directed towards the user and various measurements of height and direction can be made.
