In one embodiment, a mobile robot energizes its state-variable anchor into a released state while contacting a payload, and then de-energizes it to put it into an anchored state, attaching it to the payload. The mobile robot may then move the payload to a mounting location while the state-variable anchor is de-energized and attached to the payload. As such, the mobile robot may then energize a state-variable anchor of the payload to put it into a released state while at and contacting the mounting location, and then de-energizes it to put it into an anchored state to attach the payload to the mounting location. To then detach the state-variable anchor of the mobile robot and the mobile robot from the payload after the payload is attached to the mounting location, the mobile robot may then energize the state-variable anchor of the mobile robot to put it into a released state.

An electromagnetic pallet assembly includes electromagnetic cells coupled to a pallet base, and an electromagnetic pallet frame supported above the pallet base by pillars. A pallet central processing system is configured to control the electromagnetic cells and/or the pallet frame, and can be further configured to control an electromagnetic frame sheet located above the pallet frame. A signal adapter is configured to transmit signal between the central processing system and a remote control device. A method for adjusting pallet position includes selecting electromagnetic pallets, and activating an electromagnetic assembly of a truck bed surface and/or electromagnetic cells of the selected pallets. Polarity and/or strength of the electromagnetic assembly and/or the electromagnetic cells of the selected pallets are adjusted, and the selected pallets are moved.

An exemplary method for installing at an installation site a photovoltaic module including a panel and support legs includes disposing the photovoltaic module over a support surface such that the support legs are in a stowed position; lifting the photovoltaic module from a support surface while engaging a magnetic field with the support legs so as to maintain the support legs in the stowed position; disengaging the magnetic field from the support legs of the lifted photovoltaic module so as to release the support legs from the stowed position to an installation position in which the support legs are rotated downwards relative to the stowed position; and lowering the photovoltaic module to the installation site with the support legs in the installation position so as to install the photovoltaic module at the installation site, the support legs supporting the panel at the installation site.

A gripping device comprises a base, claws, cylinders, and an electrical-operated magnetic disk. At least two claws are pivotally coupled to the base. The base is provided with a coupling portion, which can be pivotally coupled to an arm of an operation machine. Each claw is pivotally coupled to a first location of a vertical plate of the base. Each cylinder is pivotally coupled to one of the claws. When the claws hold together, an accommodating space can be defined, in which the disk is mounted. The disk is provided with a central shaft, which can be fitted in a central space of the base. Thereby, large pieces of metal can be gripped by the claws, whereas small pieces of iron can be picked up by the electrical-operated magnetic disk, so that one machine employing the gripping device can take large pieces of metal and small pieces of iron.

An electromagnetic lifter (1) comprises at least two polar expansions (2, 3) shaped for transporting a horizontal axis coil (4) of hot-rolled steel, the polar expansions (2, 3) being connected through a ferromagnetic circuit (5) and respective cores (6, 7) around which solenoids (8, 9) are arranged, furthermore around each of said cores (6, 7) there is arranged a detection coil (10, 11) suitable to detect the change in the flux linked to the coil (4), and a control unit (16) connected to the detection coils (10, 11) compares the values detected by each of them in order to authorize or not the transport. The relevant operating method includes a first check that the difference between the values detected by the two detection coils (10, 11) is below a preset threshold, and in the affirmative a second check that the overall decrease in the linked flux is below a second preset threshold, the issue of a signal of authorization to the transport being possible only in case of positive outcome of both checks.

A tool for fishing magnetic objects through a wall includes a body portion that has a cavity formed therein. An electromagnet is secured in the cavity and is connected to a variable power source that is adapted to selectively activate the electromagnet. A pair of lines are secured to the top of the body portion so that the same can be raised or lowered a predetermined distance. The body portion includes a slot that extends into the same from the top thereof. The slot is adapted to retain an end of a fish tape therein.

The method makes it possible to neutralize surface-laid or camouflaged and in particular intelligent land mines, in that a focused beam of a powerful laser unit is automatically or manually systematically guided over the surface to be cleared of land mines in a grid pattern, the movement sequence of the laser beam being program controlled, so that the laser beam in computer-assisted manner locates the laid mines both systematically in the SCAN process and also in planned manner and neutralizes or detonates them by introducing energy.
摘要:
A lifting magnet with a gripping mechanism generally comprises a lifting magnet capable of electrically magnetized for gathering and attracting magnetic articles, such as scraps of dismantled machines, broken automobiles and electric washing machines, a main power cylinder, and a plurality of gripping arms mounted on the lifting magnet and each comprising a first arm pivotally joined at one end to the lifting magnet, a second arm pivotally joined at one end to the other end of the first arm, an auxiliary power cylinder for operating the first arm for gripping operation, and locking means for locking the second arm to the first arm when the first and second arms are folded and when the second arm is opened relative to the first arm for gripping operation. In one aspect of the present invention, only two among a plurality of the gripping arm assemblies can be used for gripping elongate articles. In another aspect of the present invention, the assembly of the lifting magnet and the gripping arm assemblies is suspended from a rotative driving mechanism so as to be turned about a vertical axis so that the gripping arm assemblies are located properly over articles to be lifted. When the gripping arm assemblies need not operate, the gripping arm assemblies are folded and stored on the lifting magnet.

An actuating magnet, particularly a direct current electromagnet, has a cylindrical magnetically permeable shell or cover made from a rectangular sheet of metal bent into a square cylinder, the edges of the sheet forming a gap. Pole plates on the ends of the shell have recesses on their edges to receive projections on the shell. The pole plates have recesses in the corners, leaving the corners uncovered to receive fastening screws.
