Compared to many six-strut hexapod configurations, this five-strut design increases the ratio of working space to build volume while providing more residual stiffness at high swivel angles.
In addition to its 5-axis machining capability, this pentapod design can also swivel through ninety degrees. The machine controller, however, accepts conventional co-ordinate information supplied by a normal numerical control program. Bosch Rexroth MHS 40 direct drives with hollow-shaft motors raise and lower the spindles. Compared to toothed-belt systems, the direct drive gives a stiffer design with fewer parts, increasing reliability. As there is no belt, no retensioning is required. Machining applications for the pentapod include models for prototypes and forms for castings.

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.
