Realizing that it’s essentially a cycloidal drive meshed with a planetary gear set, he got to work in CAD and, in seemingly no time, had a design to test. You can see the full results of his ...

The gear ratios allow you to apply more torque without needing a long handle. As you may have guessed, the internal arrangement is a planetary gear drive. You might consider if you want to print ...

The Harmonic Drive is a key part of countless robotic applications. Incredibly simple yet quite odd to watch, this gear system is extremely precise with an impressive torque-to-weight ratio, even if ...

Planetary rings are among the most intriguing structures of our solar system and have fascinated generations of astronomers. Collating emerging knowledge in the field, this volume reviews our current ...

My scientific research interests lie within the domain of numerical modelling of planetary ring systems. My PhD work focussed on writing codes to simulate and analyse the dynamics of charged dust ...

The motor is geared to the planetary ring gear. At launch, the sun is locked to the case so that power flows through the planetary carrier for an overall ratio of 17.0:1. Then around 30 mph ...

Planet position forms the base that sets the mechanics of astrology in motion. The planetary position gives the degree, minutes and seconds of the Zodiac over which celestial bodies are transiting at ...

Once upon a time, Earth may have sported a planetary ring of its very own. The hypothetical ring didn't last long, cosmically speaking – just a few tens of millions of years.

Planetary science is the study of the celestial bodies that orbit stars, with a particular focus on our own solar system. This includes studying the formation and evolution of planets, the moons ...

“Planetary alignments have always occurred—they are times when the planets in the solar system are all roughly positioned in the same direction when viewed from Earth,” said Pollacco.
