Abstract: An apparatus for working a wet coating, such as render material, applied to a surface, the apparatus comprising: an actuator arranged to move an arm across a surface having a wet coating applied thereon; a controller configured to move the arm across the surface along a tool path; and a tool head mounted to the arm, the tool head comprising a compliance module and a tool mounted to the compliance module such that the tool is movable in a stroke direction towards the surface relative to the arm. The compliance module comprises a biasing module arranged to urge the tool in the stroke direction to maintain contact between the tool and the wet coating such that the tool works the wet coating as the arm moves across the surface.

Abstract: The present application provides a method for renovation works on a building that has a plurality of building elements, for example walls. The method includes: receiving scan data of a building element of the building; (150) processing the scan data to determine at least one dimension of the building element and an initial property of the building element from the scan data; configuring (160) a building system for the building element to achieve a target property of the building element, the building system being configured according to the at least one dimension of the building element and according to the initial property of the building element; and generating instruction data (170) for fabricating the building system. There is also provided an apparatus for renovation works on a building that has a plurality of building elements, for example walls.

Abstract: There is provided a portable sensor apparatus (10) for surveying within a room (30) of a building. The sensor apparatus (10) comprises: a sensor unit (12) for temporary insertion into a room (30), the sensor unit (12) being moveable in a scanning motion, and comprising a plurality of outwardly directed sensors (16, 20, 24) arranged to capture sensor data associated with an environment of the sensor apparatus (10) as the sensor unit is moved through the scanning motion. The plurality of sensors (16, 20, 24) comprises: a rangefinder sensor (16); a thermal imaging sensor (20); and a camera (24).

Abstract: A portable survey meter for measuring radiation, the portable survey meter comprising: a radiation detector configured to perform measurements of radiation; a range sensor configured to measure range data of distances from the portable survey meter to real world structures in at least two dimensions; and a processing unit configured to align the measured range data with reference range data so as to determine an instantaneous position of the portable survey meter in at least two dimensions relative to the real world structures as a fixed frame of reference, whereby each measurement is performed at a known position.
