Manual, automated, or semi-automated articulating arm programmable tank cleaning nozzle systems, devices and methods for providing safe and efficient methods for removing paint, rust, scale, debris, and contaminants as well as methods to apply new coatings to tanks. A hydraulically controlled articulating arm can have up to 11 or more degrees of freedom and a working envelope ranging from approximately 10approximately 10approximately 10 up to approximately 50approximately 50approximately 50. Modularity and light weight components allow quick setup with minimal manpower, and therefore, make relocation in confined tanks feasible. Simplified programming with scanning methods can aide in quick generation of toolpaths. Dust free blasting techniques can be employed, making the operation safer, cleaner, and more efficient. Surface coatings can be applied with the same device further increasing efficiencies. The systems, devices and methods can work in the presence of flammable vapors and dust.

A seal member interposed between a first member and a second member. The seal member includes a seal main body attached to one of the first member and the second member, and a protection cover attached to the seal main body, and the seal main body has a seal lip having contact with or close to the other one of the first member and the second member, a bent portion formed on one end of the metal ring of the seal main body is in contact with an outer-periphery portion of the protection cover, and the seal main body is in contact with a part of the protection cover in the axial direction, and the part is located at a position different from the outer-periphery portion.

A mechanical finger for a mechanical hand, has: a proximal phalanx pivotably mountable to a support of the mechanical hand to pivot relative to the support about a finger pivot axis; a distal phalanx pivotably connected to the proximal phalanx via a first living hinge to pivot relative to the proximal phalanx about a first pivot axis; and a skeleton member pivotably connected at one end to the distal phalanx via a second living hinge to pivot relative to the distal phalanx about a second pivot axis offset from the first pivot axis and at another end operatively connected to an actuator of the mechanical hand to be selectively movable by the actuator to pivot the distal phalanx relative to the proximal phalanx and to pivot the distal phalanx relative to the support when the finger is in use.

A soft bodied robotic member has the appearance of a finger and has a deformable rubber elongated body surrounding an array of rigid ribs interconnected by a perpendicular constraint. The plates form a series of parallel protrusions extending from opposed sides of the body and have a serrated, sawtooth or wavelike appearance. A tether runs through each row of protrusions and draws the corresponding protrusions together in a compressive manner to bend or dispose the finger toward the compressed side. Gaps between the protrusion allow movement of the protrusion towards adjacent protrusions to dispose the body in an arcuate shape. The constraint is a planar sheet that bends with the arc along its width, but resists lateral twisting, thus limiting movement outside a plane defined by the arc and the tether. Multiple finger members may be placed in close geometric proximity for gripping a common object.

A track-wheel based device is disclosed. The track-wheel based device may include a longitudinal member substantially perpendicular to an axis of motion of the track-wheel based device. The track-wheel based device may further include a first lateral member and a second lateral member, each being substantially parallel to the axis of motion of the track-wheel based device. The longitudinal member may be coupled to the first lateral member at a first location of the first lateral member and to the second lateral member at a first location of the second lateral member. The first lateral member and the second lateral member may be configured to undergo a relative angular rotation, in response to a planar misalignment of four or more points of contact between two or more guide tracks for the track-wheel based device and the track-wheel based device.

The inventive concept relates to a wearable hand robot mounted on a finger to bend the finger by an external force transmitted through a wire. The wearable hand robot is capable of preventing an injury to a user's hand by the wire, achieving simplification of the structure of a finger cap and an improvement in a wearing sensation, and stably moving the finger while having a tactile sensation

Flexural digital materials are discrete parts that can be assembled into a lattice structure to produce an actuatable structure capable of coordinated reversible spatially-distributed deformation. The structure comprises a set of discrete flexural digital material units assembled according to a lattice geometry, with a majority of the discrete units being connected, or adapted to be connected, to at least two other units according to the geometry. In response to certain types of loading of the structure, a coordinated reversible spatially-distributed deformation of at least part of the structure occurs. The deformation of the structure is due to the shape or material composition of the discrete units, the configuration of connections between the units, and/or the configuration of the lattice geometry. Exemplary types of such actuatable structures include airplane wing sections and robotic leg structures. An automated process may be employed for constructing an actuatable structure from flexural digital materials.
