A metal insert keeps the polymer from
bending over during impact and allows it to collapse upon itself in a
precisely controlled manner.
Leadscrew and ballscrew drives and other critical components need fail-safe protection in emergency stop and axis over-run conditions. As an alternative to rubber bumpers and hydraulic shocks, the One-Shot Emergency Shock Absorber costs only a few dollars per use. Upon impact, the device converts kinetic energy into heat as it deforms. The company uses different high-grade polymer combinations to meet various load capacities ranging from approximately 16 to 4,000 inch-lbs.
Available with thread diameters of 3/8 and 1.25-inches, the corrosion-resistant design offers a minimum service life of 10 years, and handles -13 to 122F temperature operation.

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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
