The CMC Hybrid Roller Screw (HRS) is a low
friction recirculating roller screw that converts the rotary motion of a motor
into linear motion. The HRS incorporates a recirculating roller design;
however, the roller positioning is actively controlled allowing the HRS to
achieve rotational speeds that are comparable to traditional planetary roller
screws. The standard HRS delivers 10-20 percent more load capacity and higher
efficiencies than comparable planetary systems. The HRS can be integrated into
any product where lead screw based systems are employed or can replace any
mechanical, hydraulic or pneumatic positioner. The simplicity of the HRS is
exceptionally elegant. This simplicity allows for significant system
replacement of current technology, enabling end users to take advantage of the
higher load capacities in a similar or smaller envelope. Weight reduction is
critical in applications such as aerospace. The increase in force density that
the CMC HRS affords allows realistic replacement of hydraulic and pneumatic
systems where environmental considerations are paramount. Further, the system
is configurable to enable application specific solutions to be designed and
applied rapidly, providing remarkable flexibility. Mechanically, the HRS
couples the advantages of both planetary and recirculating roller screw devices
into a single element. Synchronization gearing is eliminated in the HRS, thus,
improving overall system efficiency compared with traditional planetary
systems. The rollers maintain active positioning within the nut body enabling
exceptional rotational speed. Further, the components within the CMC system are
conventionally machined, affording an extraordinary value in consideration of
total cost of ownership.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
