MOTION CONTROL:Exlar’s 2010 Product Catalog and Engineering Guide is now available. A manufacturer of high performance servo actuators and motors, Exlar offers seven product families featuring a broad range of capabilities with peak forces exceeding 40,000 lbf, linear speeds in excess of 60 inches per second and a life expectancy 15 times longer than that offered by ball screw technology.The 2010 Catalog details Exlar’s selection of solutions for linear and rotary motion control applications. Product families span integrated actuator and motor designs, explosion proof designs, force tube actuators, and servo motor and gearmotors. The catalog and engineering guide additionally details Exlar’s advanced roller screw and stator technology as applied to linear and rotary actuators-with drawings, performance graphs and complete specifications for various configurations and applications. With a wide array of features and capabilities, Exlar offers several robust choices matched to each application’s diverse requirements.
An easy-to-reference engineering section includes definitions and equations for determining move-profile, velocity and acceleration, force, thrust, motor velocity and torque. Also included is a table of factors for converting units of rotary inertia, torque and material densities between English and metric units.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
A recent example of a major CAE revamp is MSC Apex, released last month by MSC Software Corp. In a discussion with Design News, MSC executives noted that its next-generation platform is designed to substantially reduce CAE modeling and process time, “in some cases from weeks down to hours.”
The Thames Deckway would run for eight miles close to the river’s edge, rising and falling slightly with the tidal cycle. It will generate its own energy from a series of devices that will line the pathway and use a combination of sources to make the path self-sustaining.
