The present invention makes it possible for sounding of an inspection location on an outer wall of a building or the like to be performed using a simple operation. A user interface device accepts an input for designating an inspection location. The mobile robot device flies autonomously and moves to the inspection location, on the basis of the input into the user interface device and the current location of the mobile robot device. The mobile robot device inspects the inspection location using an inspection means such as a sounding means.

The present invention relates to a milling drum for removing glued-down floor coverings, in particular wooden floor coverings, preferably parquet floor coverings, in particular multilayer parquet, with a predetermined milling width which determines the width of a floor surface section by running the milling drum over the floor surface section to be machined, having a plurality of cutting plates which are arranged tangentially on the milling drum and which are arranged in a distributed manner on the milling drum, such that, upon a complete revolution of the milling drum, the entire milling width is operable with at least one cutting plate and such that a common width of the cutting plates being in contact simultaneously with the floor surface section to be machined is always smaller than the milling width. The present invention further relates to a surface milling cutter for removing glued-down floor coverings by use of such a milling drum, and a method for removing glued-down floor coverings by use of such a surface milling cutter.

The present invention relates to a multifunctional robot system and method. The multifunctional robot system comprises an independently movable supply station and a plurality of robot units. The supply station comprises a power supply system and a supply station moving device; each robot unit is provided with a robot driving device, an operation execution device and a robot moving device; the supply station is connected with each robot unit respectively through a connecting cable. The multifunctional robot system is provided with the independent supply station, and the execution device of the robot is separated from the driving device thereof and a supply device; the supply station continuously provides raw materials and energy for the robot, the weight and size of the robot side are reduced, and working efficiency is improved.

An apparatus for treating a surface of a structure includes a main carriage having an accessory carriage that is vertically movable with respect to the main carriage.

A walk-behind floor scraper machine for removing floor covering from a floor surface is disclosed. In one aspect, the machine includes a base frame, an electric motor secured to the base frame, and a scraper assembly movably secured to the base frame and driven by the electric motor. The machine also includes a rear wheel arrangement including a pair of wheels having a rotational axis. In one aspect, the machine includes a hydraulic circuit with a hydraulic pump driven by the electric motor and a hydraulic motor powered by the hydraulic pump. The hydraulic motor has a drive axle coupled to the wheels, wherein the drive axle is coaxially aligned with the rotational axis. In one aspect, the machine can include a hydraulic tank-frame integral to the chassis of the machine that simultaneously stores hydraulic fluid and structurally supports the hydraulic motor.

A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

The present invention refers to a new concrete composition comprising fiberglass waste and an air-entraining additive. The concrete presents a thermo-insulating performance far superior to conventionally produced concretes. The present invention is mainly intended for the construction industry, in non-structural applications for thermal insulation. The use of fiberglass waste reduces the consumption of natural aggregates and allows for the use of waste which is expense to dispose of.
