MOTION CONTROL: The model AZ1040 drive from Amacoil Inc. is the most recent extension to the Amacoil-Uhing line of timing belt drives used for smooth linear motion in positioning and indexing applications. The drive features a one-piece aluminum profile extrusion which serves as the belt housing. T-slots and receiver grooves for the load carriage guide bars are incorporated into the profile design. The one-piece construction permits longer, sag-free stroke lengths without necessitating scaling up to a larger size drive. In cross-section, the profile reveals a dynamic crisscross structural pattern which further increases sag resistance and overall durability.
Belt pulleys are built-in to the AZ1040 end caps. T-slots are also designed into the end caps which provide more options for mounting and integration with other assembly components. The load carriage measures 188 mm x 160 mm (7.4 inches x 6.3 inches) and has pre-drilled and tapped payload mounting holes, and also T-slots running parallel to the line of travel. Maximum travel speed is up to 5.0 meters/second (16.4 ft/sec) depending on the weight of the payload which will also affect required drive torque and acceleration capability. The drive has a repeatability of +/- 0.2 mm (0.008 inches) over travel spans of up to 2,000 mm (6.5 ft).
Amacoil-Uhing AZ1040 timing belts are made of a heavy-duty synthetic rubber with a built-in steel cord strengthener. Multiple profile sections may be joined to accommodate long travel requirements. Five different AZ models are offered all of which are distributed in the USA by Amacoil, Inc.
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.
