A system and method to transform reconfigurable structures into systems with continuous equilibrium. The system and method are based on adding optimized springs that counteract gravity to achieve a system with a nearly flat potential energy curve. The resulting structures can move or reconfigure effortlessly through their kinematic paths and remain stable in all configurations. The method enhances system design to maintain continuous equilibrium during reorientation, so that a system maintains a nearly flat potential energy curve even when it is rotated in space. This ability to reorient while maintaining continuous equilibrium greatly enhances the versatility of deployable and reconfigurable structures by ensuring they remain efficient and stable for use in different scenarios.

Disclosed is a decontamination robot. The robot includes a decontamination box including at least two arrays of ultraviolet LEDs, the two arrays arranged to irradiate an object placed inside the decontamination box from at least two independent directions, the decontamination box further including an interior surface with at least 90% reflectivity of ultraviolet light. The robot also includes a drivetrain including four swerve-drive units, each swerve-drive unit capable of rotating a wheel on an axis of the wheel and capable of orienting the wheel in a plane defined by the axes of the four wheels of the four swerve-drive units, whereby the four swerve-drive units coordinate to generate translational motion of the decontamination robot on a working surface. The robot also includes a scissor lift capable of raising the decontamination box from a first position to a second position, wherein the scissor lift comprises a plurality of bars connected by a plurality of joints such that the plurality of bars form a series of crosses, and a top plate attached to a top of the decontamination box.

A lifting and supporting table according to the present invention includes an upper platform having a receiving surface and a lower frame supporting the upper platform. The lifting and supporting table includes a linkage interacting with the lower frame such that adjustment of the linkage forces a height of the upper platform to change. A ramp assembly includes a ramp having a top surface that operatively extends the receiving surface of the upper platform, the ramp being selectively moveable between a horizontal position and an inclined position.

The invention relates to a scissor arm assembly for a scissor lift, comprising two scissor arms (124, 125) pivotally mounted about a shaft (70). Each arm is made of a tubular beam having a local reinforcement plate (80, 81, 82) welded on either side. Each arm (124, 125) has two through-holes (101, 102; 103, 104) for the shaft (70), each of which is made in a respective side of the beam and the corresponding reinforcement plate. The shaft (70) is circumferentially supported in each hole by both the wall of the beam and the corresponding reinforcement plate (80, 81, 82). The shaft is free of support inside the beam between the two through-holes (101, 102; 103, 104). This avoids having to weld, on either side of the scissor beam, a part inserted therein to house the shaft (70).

A transportable drive-over conveyor system includes a drive-over hopper for receiving material and having a belt-type conveyor for conveying the material, a transition section pivotally connected to the drive-over hopper, an auger mounted at a downstream end of the transition section, and wheels beneath the auger that support and move the conveyor system. At least one wheel is a drive wheel. The wheels may be radially offset. The wheels may be arced to travel in arced tracks.
