What is Arduino ? 51052

“It’s an open-source physical computing platform” 

Arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. It’s an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board.

Raffaello D'Andrea: The astounding athletic power of quadcopters

The Athletic Power of Quadcopters 11113

In a Robot Lab at TEDGlobal, Raffaello D’Andrea demos his flying quadcopters: robots that think like athletes, solving physical problems with algorithms that help them learn. In a series of nifty demos, D’Andrea show drones that play catch, balance and make decisions together — and watch out for an I-want-this-now demo of Kinect-controlled quads.

cam and follower (MECHANISM) IN PRO-E

Robotic Mechanisms – CAM MECHANISMS 51050

A cam is a mechanical component capable of transmitting motion to a follower by direct contact. In a cam mechanism, the cam is the driver and the driven member is called the follower. The follower can remain Stationary, translate, oscillate, or rotate.

Basics of Sprockets and Roller Chain


A sprocket or sprocket-wheel is a profiled wheel with teeth, cogs, or even sprockets that mesh with a chain, track or other perforated or indented material. The name ‘sprocket‘ applies generally to any wheel upon which are radial projections that engage a chain passing over it.


Robotic Mechanisms – MAGNETIC GEARS 51043

Compared with mechanical gears, magnetic gears is claimed to offer advantages including reduced maintenance, improved reliability, no need for lubricants, higher efficiency, precise peak torque transmission, inherent overload protection, reduced drivetrain pulsations, tolerance of misalignment and low noise. In some applications, it is also beneficial that the input and output shafts are physically isolated.

Unusual gears

Robotic Mechanisms – NON CIRCULAR GEARS 51041

non-circular gear (NCG) is a special gear design with special characteristics and purpose. While a regular gear is optimized to transmit torque to another engaged member with minimum noise and wear and with maximum efficiency, a non-circular gear’s main objective might be ratio variations, axle displacement oscillationsand more.

Robotic Mechanisms – CAGE Gears 51040

cage gear, also called a lantern gear or lantern pinion has cylindrical rods for teeth, parallel to the axle and arranged in a circle around it, much as the bars on a round bird cage or lantern.
