Robot Navigation with a Particle Filter

As robots become smarter, faster and more capable, they are being developed to perform increasingly complex tasks. In order to perform these tasks properly, robots are becoming more and more dependent on accurate navigation through the environment in which they operate. Somewhere in the future, if intelligent robots were to rise up and demand fundamental rights, I think one of the first things they would ask for is the answer to the question, “Where am I?”.

Where am I?

Removing Noise : The Versatile Complementary Filter

After playing around with DC electronics for almost a year now, I thought it was finally time to start mucking about in the world of Alternating Current. To begin, I decided to experiment with the ACS712 Current Sensor.

Analemma of the Sun

I recently read that to date, Mount Everest has been scaled 1924 times.

Compare this figure to the number of people who have successfully captured the Analemma of the Sun. Any guesses? 1000, maybe 500? Nowhere even close. According to the founder of this website, in the entire history of mankind, not more than 20 people have managed to get it right.

This is the first ever photograph that successfully captured the Analemma. It was taken over a period of one year by Dennis di Cicco in 1978.
