A foldable low-profile weightlifting bench that includes a platform, pivotable support legs, and pivotable weightlifting bar support arms adapted such that the foldable low-profile weightlifting bench can be folded into a storage configuration capable of fitting under a typical bed frame.

A retractable exercise rack system for efficiently securing an exercise rack against or near a wall when the exercise rack is not in use. The retractable exercise rack system may thus be adjustable between a retracted position against or near the wall, and an extended position which is distally-positioned with respect to the wall. The retractable exercise rack system generally includes a first support member a second support member, with an exercise bar connected between the support members. Wall mounts may be secured to the wall, with the first and second support members being adjustably connected to the wall mounts by linkages, scissor connectors, or arms. Latches and strikers may be utilized to releasably lock the support members in the extended and/or retracted positions. One or both of the support members may include a button for releasing the latches from the strikers.

Provided is a system for robotic collaboration. A first robotic device includes a tangible, non-transitory, machine readable medium storing instructions that when executed by a processor of the first robotic device effectuates first operations including: receiving first information from a processor of a second robotic device; actuating the first robotic device to execute a first action based on the first information; and transmitting second information to the processor of the second robotic device. The second robotic device includes a tangible, non-transitory, machine readable medium storing instructions that when executed by the processor of the second robotic device effectuates second operations including: receiving the second information transmitted from the processor of the first robotic device; actuating the second robotic device to execute a second action based on the second information; and transmitting third information to the processor of the first robotic device.

A ball collection apparatus constituted of: a control circuitry; a body; motors; wheels arranged to rotate responsive to the motors, the body arranged to move along a surface responsive to the rotation of the plurality of wheels; a collection compartment arranged to maintain a ball within a predetermined area in relation to the body; a ball input port in communication with the collection compartment; and a ball ejector arranged to eject the ball from the collection compartment, wherein the control circuitry is arranged to: receive information regarding the location of the ball; responsive to the received information, control the at least one motor to advance the body towards the location of the ball, the collection compartment arranged to collect the ball through the ball input port; and control the ball ejector to eject the ball from the collection compartment and propel the ejected ball towards a predetermined target area.

A multifunctional chair is provided. The multifunctional chair includes a supporting body, a telescopic structure, a seat body, and a pedal assembly. The pedal assembly includes a fixing rod, a movable rod, an operation portion, and an elastic resistance member. The telescopic structure is connected to the supporting body and configured to be operated to telescopically move relative to the supporting body. One end of the fixing rod is fixed to the supporting body. The movable rod is movably connected to the fixing rod. The operation portion is arranged at an end of the movable rod away from the fixing rod. Two ends of the elastic resistance member are respectively connected to the supporting body and the fixing rod. A user can push against the operation portion to rotate the movable rod and the fixing rod toward the ground, and the elastic resistance member provides an elastic resistance.

A cart assembly that is designed to hold and transport one or more ball hoppers. The ball hoppers have baskets that are supported by legs. The baskets are configured to hold some type of ball, such as a tennis ball or a golf ball. The cart assembly can transport the ball hoppers as they are standing on legs. The cart assembly has a platform that is supported by wheels. The wheels provide the platform with the ability to roll. Receptacles are present on the platform. The receptacles are sized, shaped and positioned to receive the legs of a ball hopper when the ball hopper is placed on the platform. Once a ball hopper is attached to the platform, the ball hopper becomes part of the cart assembly and can roll with the cart assembly from point to point.

A transformable exercise apparatus is disclosed. The exercise apparatus includes base arms parallel to each other, front legs and rear legs extending from the base arms. The exercise apparatus includes top arms, each connecting respective front and rear leg of each base arm. The exercise apparatus presents telescopic members stored in the front legs. The exercise apparatus includes a first table top and a second table top. The second table top includes collapsible legs. The collapsible legs fold and allow for placing the second table top and the first table top over the top arms, thereby transforming the exercise apparatus into a furniture. The second table top demounts and transforms into a workbench. The telescopic members extend and include a pull-up bar at the top, transforming the exercise apparatus into a pull up exercise apparatus. The apparatus may transfer into a leg press and arm press.

An apparatus for teaching baseball pitching includes a substantially flat panel having a substantially rectangular shape with adjustable height and width dimensions. The apparatus further includes at least two support members for supporting the flat panel in an upright position. The length of the support members can be adjusted to obtain a desired distance between a bottom edge of the flat panel and the ground.

A functional training rig kit includes a box and a plurality of components adapted to fit within the box. At least some of the components and the box include elements by which the components are adapted to be attached to the outside of the box to provide at least one functional training rig attached to the outside of the box.

An in-goal ball return device, the ball return device is a material implement having a front edge, side edges, and a rear edge. The device is configured for attachment within a goal, the goal having a supporting net mesh. The device has a plurality of closed loops disposed along the rear edge and side edges. The device includes a lacing cord for threading through any number of the closed loops and the net to secure the material implement to the net mesh. The device forms a continuous angled surface between the front and closed portion of the goal when attached.
