CARA: A Rope-Driven Quadruped Robot Without Gears or Pulleys Over the past year, Aaed Musa built a robot dog called CARA, short for "Capstans Are Really Awesome". The design does not involve gears or pulleys like traditional ones. CARA uses something called capstan drives that move joints using ropes wrapped around rotating drums. This system has numerous advantages, such as zero backlash, high torque transparency, low inertia, low noise, and low cost… |

Measure Sound/Noise Level in dB with Microphone and Arduino Noise pollution has really started to gain importance due to high population density. A normal human ear could hear sound levels from 0dB to 140dB in which sound levels from 120dB to 140dB are considered to be noise. Loudness or sound levels are commonly measured in decibel(dB), we have some instruments which could measure the sound signals in dB but these meters are… |

Harmonic Filter Circuit: How to remove Harmonics using Active and Passive Harmonic FiltersWhat is Harmonics in Electrical System?
In power systems, harmonics are defined as positive integer multiples of the fundamental frequency. Harmonic is a voltage or current occurs at a multiple of the fundamental frequency. It is often regarded as noise in the power line. The harmonics in the power system can be classified into two types: current… |
