Described herein is an arm supporting exoskeleton, comprising an arm link mechanism. The arm link mechanism comprises a proximal link, a distal link, an arm coupler, and a variable force generator. The distal link is rotatable relative to the proximal link. The arm coupler is adapted to couple an upper arm of a person to the distal link. The variable force generator comprises a first spring and a second spring, configured to create a torque between the proximal link and the distal link. In the first force mode, the variable force generator exhibits a first stiffness rate defined by the first spring that supports the upper arm of the person against gravity forces and. In the second force mode, the variable force generator exhibits a second stiffness rate defined by the first spring and the second spring that supports the upper arm of the person against the gravity forces.

A system suitable for use as a portable tradesperson workstation is presented. The system includes a main table configured to support and connect with a material working apparatus, the main table positionable on top of and connected to associated adjustable support legs. The system also includes two center adjustment brackets positionable on top of and connected to opposite ends of the main table. Additionally, the system includes a preparation area extension, with associated adjustable support legs, connected to the main table with one of the center adjustment brackets on a top left-hand side of the main table. Further, the system includes a post product working area extension, with associated adjustable support legs, connected to the main table with the other center adjustment bracket on a top right-hand side of the main table. The system is configured to form an assembly and configured for transportation as a portable tradesperson workstation.

A work table includes a baseplate, a plurality of levers, a clamp plate, a lock mechanism, and an unlocking mechanism. The plurality of levers are disposed on a concentric circle on the baseplate. Guide bars protrude upward from the plurality of levers. The plurality of levers are each disposed to be movable in a radial direction of the circle. The clamp plate is placed on top surfaces of the levers. The clamp plate has elongated holes in the radial direction through which the guide bars penetrate. The lock mechanism urges the clamp plate downward such that the respective levers are fixed in a manner sandwiched between the baseplate and the clamp plate. The unlocking mechanism releases the fixing of the respective levers by the lock mechanism.

One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are expandable to provide a surface to perform work.
