Boston Dynamics Spot, the robot dog!

You would have known  Boston Dynamics,  a world leader in mobile robots (that's why they have "Dynamics" in their name!). They create robots with advanced mobility, dexterity and intelligence. One of the most famous is the humanoid robot Atlas, whose hobby is parkour! FUN FACT:  Those guys kick their robots to test stability! Recently in June, the Boston Dynamics debuted sales for Spot, the agile robot that climbs stairs and traverses rough terrain with ease. FEATURES MOBILITY Spot's leg was designed to move fast ( 1.6 m/s ). The system automatically adapts to keep the robot moving smoothly. It knows how to climb stairs and avoid wars. Spot can also "get up" when it falls most of the time PERCEPTIVE Spot cameras on all four sides to know where it is walking.  AUTONOMOUS Spot's movements are remote-controlled by an operator. But Spot can automatically do some basic things. Spot also comes equipped with  Autowalk , an easy-to-use tablet feature that allows

Earth's Magnetic Field is splitting into Two! NASA Announced.

The SAA (South Atlantic Anomaly) present over South America and South Atlantic Ocean is weakening.  As it gets bigger, it expands westwards and split the magnetic field into two!  NASA says that it can poses little risk to life!  WHAT IS SAA? The South Atlantic Anamoly (SAA) is an evolving weak spot of Earth's Magnetic Field. This unique region has been expanding for over a decade. NASA concludes that it is splitting into two distinct zones.     HOW DID EARTH GET  A MAGNETIC FIELD? To understand the consequence of splitting, we have to know about magnetic fields. Processes of Earth's iron outer core generates the electric field continuously. This makes the most part of the magnetic field. The magnetic field acts like a shield preventing harmful particles from the sun. The particles are trapped by the magnetic field and thus, prevents it from reaching the surface. SO WHAT'S WITH SAA? The mantle and core magnetic variations below the SAA are the causes. Due to the reducti

Discovery of the closest asteroid by IIT Bombay students.

On  August 16 2020 ,  An asteroid sized 3 to 6 metres (10 to 20 feet) was found just 2950 km above the Earth's surface! The astonishing discovery was recorded by the students of IIT Bombay and Taiwan.   Helping make a discovery like this, so early in my research project, is beyond what I had ever imagined   -Sharma,  a third-year student of mechanical engineering at IIT-B. Named  2020QG,  the closest asteroid ever to be found near Earth without impacting it became an early success for the students. The discovers Kunal Deshmukh and Kritti Sharma and Chen-Yen Hsu at National Central University in Taiwan are a part of an international team seeking out Near-Earth Asteroids.          This is the first image of Asteroid 2020 QG, captured by Caltech's Zwicky Transient Facility (ZTF) after the asteroid's closest approach to Earth at a distance of 1,830 miles above the planet's surface. The asteroid shows up as a stre
