Depends on the application. Moving the mass away from the center point of rotation will increases the moment of inertia. Which means it will resist influences from external forces more. This includes both environmental disturbances and self generated motion command updates. Hexacopter arm angle. Electronic Lock using Switches: Circuit Diagram. Assemble the circuit properly.

Electronic Lock using Switches: Circuit Diagram

The switch we are using is push to make switch means when you press the switch it conducts and when you release the button switch become disconnected. Line Following Robot using LDR and L293D IC: Circuit Diagram. In this circuit we are using L293D IC as a motor diver IC to control the movements of motors and we are using LDR's as a sensor which will sense the path for the robot to follow.

Line Following Robot using LDR and L293D IC: Circuit Diagram

Before understanding the working lets understand the working of individual components. 1.LDR which is working as a sensor here. LDR is basically made up of semiconductor material. Semiconductor material has energy band where electrons and holes exist. Line Following Robot using LDR and L293D IC: Circuit Diagram. 2 - Digit Object Counter Circuit Diagram. As shown in circuit diagram the major components of circuit are sensor, decade counter cum display driver chip CD4026 and common cathode type 7-segment display. · The IR LED and photo diode together are used as object sensor.

2 - Digit Object Counter Circuit Diagram

Both are placed near to each other and their direction is also same · IR LED continuously emits IR light because it’s given 5 V through current limiting resistor · Photo diode is connected in reverse bias so normally it does not conduct and gives high output · Its output is given to base input of NPN type transistor Q2 which is connected in switch configuration · Output of Q2 is given to base input of another NPN transistor Q1 that is also connected in switch configuration · Finally output of Q1 is given to clock input to first decade counter chip CD4026. 12v to USB adapter \ 12v to 5v transformer (great for cars) : LED indicator.

Spur Gear Design ~ Learn Engineering. Mechanical engineers working in transmission field would often have to decide upon kind of gears they have to use.

Spur Gear Design ~ Learn Engineering

Although this task has become a matter of selection of gear based on standards, it is also important to know what goes behind this. In this video tutorial you will learn how to design a pair of spur gears for mechanical strength, surface resistance and fluctuating load. The video lecture is described below in detail AGMA Standard of Gear Design A designed gear should meet following design criteria conforming to AGMA standards. How Home Base homing works?

Wi-Fi-powered electronics make Nikola Tesla's dream a reality

Making wires redundant was one of Nikola Tesla’s biggest dreams – a dream University of Washington researchers want to fulfill with PoWiFi. Shyam Gollakota and his team recently demonstrated technology at EmTech Digital in San Francisco that harvests ambient ‘backscatter’ radio signals to power battery-free temperature and camera sensors. The technology can also be used to charge nickel–metal hydride and lithium-ion coin-cell batteries at distances of up to 28 feet. In a recent paper describing their work, called Powering the Next Billion Devices with Wi-Fi, the researchers provide a detailed description of how they successfully powered devices over WiFi using existing Wi-Fi chipsets–without reducing the router’s performance. Details after the jump. The researchers note that Nikola Tesla dreamed of getting rid of wires.

Counting the Problems of Robot-Assisted Surgery. Among the critics: Dr.

Counting the Problems of Robot-Assisted Surgery

Marty Makary of Johns Hopkins University Hospital and author of the book, "Unaccountable," who believes the number of injuries and complications are under reported. Controversy Over Surgical Robotics Heats Up. Thirteen years ago Intuitive Surgical's da Vinci robot was hailed as a revolution in the operating room, triggering a hot IPO and an even hotter stock.

Controversy Over Surgical Robotics Heats Up

At its peak, the stock traded at nearly $600, versus around $500 now. But with first quarter earnings reported Thursday, critics were scrutinizing the numbers for any signs of weakness. First quarter revenue, reported after Thursday's market close, beat on the top and bottom lines, but there was a hitch: Procedure growth of 18 percent trailed analyst expectations of around 21 percent. Procedure growth is a critical metric—one closely watched by investors looking for any sign that the mounting controversy and legal issues over injuries and deaths allegedly related to da Vinci procedures are affecting the company's growth.

Sales growth in recent quarters has slowed, but at 23 percent in each of the last two quarters is robust by most standards. "We are pleased with our first quarter revenue and earnings growth. Origami Robot Folds Itself Up, Does Cool Stuff, Dissolves Into Nothing. At ICRA 2015 in Seattle yesterday, researchers from MIT demonstrated an untethered miniature origami robot that self-folds, walks, swims, and degrades. Designing mechanical parts for 3D printing. What you need to know. Through these pictures and explanations we hope to give you a better understanding on how to design mechanical parts for 3D printing. Executive summary: maintain a wall thickness of at least 1mm, accuracy is 0.1mm, always keep a clearance of 0.6mm and parts may have a deviation of 0.2mm. When designing something mechanical that has to be 3D printed or when adding a mechanical feature to your model there are several main considerations. Material properties & limitations For the purposes of this tutorial we will use the White, Strong & Flexible material.

K-12 Robotics. Robotics is a great way to get kids excited about science, technology, engineering, and math (STEM) topics. Studies show that it is highly effective in developing team-work and self-confidence. This web site is designed to help K-12 and other educators in developing or improving courses that use robotics as a tool for teaching STEM topics or as a topic in itself. The materials on this site include down-loadable lesson plans and links to other useful resources, such as teacher training workshops, public robotic contests, and other educational robotics web sites. We strongly encourage NSF-funded investigators to consider participating in the NSF RET Program, thereby involving K-12 teachers in state-of-the-art research and innovative curricular development.

Intro CS Assignments. Micromouse classic. Coding A* Pathfinding. How to Calculate Time and Distance from Acceleration and Velocity. In a physics equation, given a constant acceleration and the change in velocity of an object, you can figure out both the time involved and the distance traveled. For instance, imagine you’re a drag racer. Your acceleration is 26.6 meters per second2, and your final speed is 146.3 meters per second. Now find the total distance traveled. Got you, huh? “Not at all,” you say, supremely confident. You know the acceleration and the final speed, and you want to know the total distance required to get to that speed.
