Soft Robots Mimic Biological Movements

At Harvard University, researchers have developed a model for designing soft robots. The special features of these robots include bending as a human index finger does and twisting like a thumb when a single pressure source powers the robots. For long, scientists have followed a process of trial and error for designing a soft robot that moves organically—twisting as a human wrist does, or bending just like a finger. Now, at the Wyss Institute for Biologically inspired Engineering and the Harvard Read more [...]

Monitor Appliances with Raspberry Pi

We use many appliances to help us around the house and office. However, most of them are not smart enough to inform us when they have finished the chore allotted to them. That means we have to leave whatever we are doing at intervals to check and monitor the state of the appliances. This reduces our efficiency for doing important work requiring long stretches of concentration. All this can be set right if you have the single board computer, the Raspberry Pi (RBPi) readily available. You can program Read more [...]

What are Miniature Circuit Breakers?

Most places that earlier used fuses in low voltage electrical networks now commonly use miniature circuit breakers (MCB) instead. Although an MCB is much larger than a fuse holder is, the MCB has several advantages when compared to fuses. Any abnormal condition of the network, meaning overload or fault conditions, causes the MCB to sense and automatically switch off the electrical circuit. While a fuse does not sense it, the MCB senses the abnormality in a more reliable way. Additionally, the Read more [...]

LCD Touchscreens for the Raspberry Pi

Those using the single board computer, the Raspberry Pi (RBPi), can now get several high-resolution LCD screen models on the market. While they are cheap, some are designed to integrate with the RBPi specifically. SunFounder, a company specializing in accessories and kits for RBPi and Arduinos, produce a series of these screens. For satisfying different segments in the market, SunFounder has lately produced and is marketing a number of models with varying price ranges. SunFounder LCD 10.1” HD With Read more [...]

3D Printers: Change the Shape of Your 3D-Printed Objects

When you print 3D objects on your 3D printers, they remain stable. Other than deteriorating over time, the objects do not change by themselves. However, that may be changing now. Scientists at MIT have created a new technique of printing 3-D objects where you can change the polymers in the object after printing. That means change the color of the object, grow or shrink it, or even change its shape entirely. Associate Professor of Chemistry at MIT, Jeremiah Johnson led the research, along with Read more [...]

IOT: The Internet of Things Helps Manage Decisions

In any era, one of the characteristics of a good leader has always been their ability to take a good decision with the limited information available to them. According to the 26th US President Theodore Roosevelt, the best thing to do in a moment of decision is doing the right thing, the next best thing is doing the wrong thing, while the worst that anyone can do is doing nothing. This brings us to the IOT Expectations are the Internet of Things (IoT) will be networking billions upon billions of Read more [...]

How Do Air and Magnetic Hydraulic Circuit Breakers work?

Circuit breakers have replaced fuses in most electric circuits. As these are easy to select, install, and maintain, circuit breakers are more commonly employed as protection against over-current and shorts. For different applications, there are various types of circuit breakers available in the market. We will discuss two of them. Air Circuit Breakers Air circuit breakers use air as the medium for extinguishing the arc formed when the breaker trips. The air is usually kept in compressed form Read more [...]

Bipedal Robots Walk Agilely on Two Legs

At the New Economic Summit (NEST) 2016 conference, in Tokyo, Japan, Andy Rubin unveiled an awesome new bipedal robot from SCHAFT. The new robot can easily climb stairs, carry a payload weighing 60 kilos, balance on a pipe, and move in tight spaces. In fact, they even showed a video where the robot can be seen climbing a narrow staircase. By positioning its legs behind its body, the robot is shown cleaning the stairs using a spinning brush and a vacuum type appendage attached to its feet. The video Read more [...]

The Raspberry Pi MeARM

Arms are a favorite with robotic enthusiasts. The number of joints in an arm ensures this. For instance, an arm can be made to rotate a full circle, and bend to almost at right angles. Each finger on an arm can be manipulated independently, and each finger can have at least three joints. Therefore, an arm with even two fingers and an opposing thumb can pick up objects—with pressure sensing. A simple project such as an arm can become as complicated as one can make it. The above reasons made the Read more [...]

How Long Does it take for a Circuit Breaker to Operate?

Electrical power systems all over the world use circuit breakers as important and critical components. As they play a key role, engineers periodically test circuit breakers. One of the most important test methods is the timing test, which measures the mechanical operating time of the breaker’s contacts. A timing test averts damage to a circuit breaker, as the incorrect operation of a circuit breaker prevents fatal consequences on connected equipment and substation personnel. Various measuring Read more [...]
