Disclosed in the present invention is an autonomous vehicle (), which comprises an housing (), an driving module mounted on the housing (), an borderline detecting module mounted on the housing for detecting the distance between the autonomous vehicle () and the borderline (), an energy module mounted on the housing for providing energy for the autonomous vehicle, and an control module electrically connected with the driving module and the borderline detecting module. The control module controls the driving module to perform steering based on the signal representing the angle relationship between the autonomous vehicle () and the borderline () transmitted from the borderline detecting module, so that the axis () of the autonomous vehicle () always forms an acute angle or an right angle with one side of the borderline () while steering is completed, but another side of the borderline () forms an acute angle or an right angle with the core axis () of the autonomous vehicle () when the turning begins. The turning has directivity, so that the autonomous vehicle more easily goes out from the narrow area and the efficiency of area covering is higher; moving is kept during the turning, so that the energy is saved, and the working efficiency is improved.

Autonomous working system, an autonomous vehicle and a turning method thereof

A robotic mowing system that includes a station and a robotic mower. The robotic mower has a controller and a memorizer, the memorizer stores a working procedure, and after receiving a start command input by a user, the controller executes the working procedure, so as to control the robotic mower to automatically and repeatedly mow and return to the station to be charged until the controller receives a stop command. In this way, the user does not need to input working parameters, and costs are relatively low.

A portable washing device, including: a housing, a motor arranged in the housing, a pump driven by the motor, a container for storing washing liquid connected to the pump, a spraying pistol held and controlled by a user connected to the pump, the liquid spraying out from the spraying pistol, the pistol comprises a control unit for controlling the portable washing device.

Portable washing device

The present invention refers to a robot, a docking system and a docking method therefor. The docking system comprises a first circuit located in a robot. The first circuit comprises a power storage unit for supplying power to the robot and a first main control unit for controlling the movement of the robot. The docking system further comprises a first group of terminals electrically connected with the first circuit, and a second circuit located in a docking station. The second circuit comprises a power supplying unit. The docking system further comprises a second group of terminals electrically connected with the second circuit. The power storage unit or the power supplying unit provides a detection power. The detection power generates a detection current when it flows across a detection circuit. The detection circuit is constructed by the first circuit and the second circuit through the first group of terminals docking with the second group of terminals. The detection circuit further comprises a current detection unit, and the first main control unit confirms that the first group of terminals dock with the second group of terminals when the detection current is detected by the current detection unit. The robot according to this invention can reliably dock to the docking station without human intervention, which brings extreme convenience to production and life.

Robot, a docking system and a docking method

The invention relates to a power tool, which comprises a motor for driving a tool bit rotating, the motor attains a rotational speed, a source for supplying an electric current to said motor, a sensor for measuring said current, and a control device. The control device fulfills the task of detection of a variation of the slope of the current in the course of time, and generates a control signal. The rotational speed of the tool is reduced in response to the control signal. The present invention automatically detects whether the work piece operated by the tool bit reaches a predetermined position by providing electronic control means. It may make sure that the screw is driven into a piece of wood and does not go beyond the predetermined position once detect that the work piece reaches the position and carries out the changing action.

Controlling method of electric tool and electric tool carrying out the controlling method

A power tool comprising a housing, a motor, an output shaft, a gear transmission mechanism and a control system. The gear transmission mechanism is connected between the motor and the output shaft to transmit the rotary power of the motor to the output shaft. The gear transmission mechanism has a high speed position and a low speed position. The control system is coupled to the gear transmission mechanism for detecting an operating characteristic of the power tool to actuate a ring gear to automatically move from the high speed position to the low speed position and to reduce the rotational speed of the ring gear when the operating characteristic exceeding a predetermined value.

Power tool having control system for changing rotational speed of output shaft

A power tool includes a housing, a motor, an output shaft, a gear transmission mechanism and a control system. The gear transmission mechanism is connected between the motor and the output shaft to transmit the rotary power of the motor to the output shaft. The power tool includes a signal generator and a control system electrically coupled to the signal generator and operatively engaged with the gear transmission mechanism such that when the signal generator is manually activated, an electric signal is generated and transmitted to the control system to cause the gear transmission mechanism to vary the gear reduction ratio.

Power tool with signal generator

The device () comprises a laser () which is attached to the tool (). During operation a laser beam () is emitted onto an optical lens () which is of cylindrical shape. The lens () is suspended to swivel freely, e. g. by means of a swivel arm () which is operatively connected to the tool (). Thus, the main axis () of the lens () is kept vertically by the gravity force when the tool () is moved or tilted. The shape of the laser marker (III, III) generated on a workpiece () is an indication for the user of the tool () concerning an inclination (x, y) of the tool ().

Device for determining the inclination of a tool, such as an electric drill

A tool for shaping a material which, in use, generates dust. The tool (e.g., sander) has an outlet for discharging air and dust, a dust recovery chamber which is sealed during operation and at least one cyclone. The cyclone has an inlet port which is coupled to the outlet, an outlet port which communicates with the dust recovery chamber and an air vent from which cleaned air is expelled.

Cyclonic tool

The present invention relates to an anti-vibration arrangement () for a power sander () which comprises a housing (), a motor () arranged in the housing (), a rotary drive shaft (), a first outer or ring-shaped pad surface () for attaching a first sanding paper () and a second inner or circular pad surface () for attaching a second sanding paper (). The anti-vibration arrangement () serves to transfer energy from the motor () to the pads () with out-of-phase motions to dynamically compensate for inertial and friction forces. For this purpose, twin cams () are fixed on the rotary drive shaft (). The cams () rotate the central axes () of the pads () about the rotary drive shaft axis () with a phase differential of typically 180&#xb0;. Vibration which would otherwise be transmitted to the rotary drive shaft () and from there to the operator of the machine () are drastically reduced irrespective of whether or not the operator increases the applied force () in order to increase the sanding depth or to speed up the sanding operation.
