One major drawback to working with motors is the large amounts of electrical noise they produce. This noise can interfere with your sensors and can even impair your microcontroller by causing voltage dips on your regulated power line. Large enough voltage dips can corrupt the data in microcontroller registers or cause the microcontroller to reset.

As www.robotee.com we search for good Learning Resources for robot, robotics and robot designers. In this Tutorial Series we have examined Arduino, Uno, Leonardo, etc. in lots of usefull applications.
The first Arduino tutorial on getting started and connecting it to your PC. In this video I cover the following:
The BASIC Stamp is a microcontroller with a small, specialized BASIC interpreter (PBASIC) built into ROM. It is made by Parallax, Inc. and has been popular with electronics hobbyists, robotic designers since the early 1990′s because of its low threshold of learning and ease of use due to its simple to understand BASIC language and excellent documentation. It is called a “Stamp” simply because it is close to the size of an average postage stamp.
Anywhere you would like to add intelligence you use a Microcontroller…
A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.
The Handy Board is a 6811-based microcontroller system that lets you build mobile robots for educational, hobbyist, and industrial purposes. People use the Handy Board to run robot design courses and competitions at the university and high school level, build robots for fun, and control industrial devices.
Servo motors have been around for a long time and are utilized in many applications. They are small in size but pack a big punch and are very energy-efficient. Because of these features, they can be used to operate remote-controlled or radio-controlled toy cars, robots and airplanes.

What is a Stepper Motor ?
A stepper motor (or step motor) is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.
Geared motors are used in robotics where high torque is needed. A geared DC Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM .The gear assembly helps in increasing the torque and reducing the speed.
Short Answer: With the advent of cheap computers and power transistors, it became possible to “turn the motor inside out” and eliminate the brushes. In a brushless DC motor (BLDC), you put the permanent magnets on the rotor and you move the electromagnets to the stator.

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.
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.
Pulleys and Belts transfer rotating motion from one shaft to another. Essentially, pulleys are gears without teeth that depend on the frictional forces of connecting belts, chains, ropes, or cables to transfer torque.
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.

How To Make Wooden Gears Online GEAR GENERATOR http://woodgears.ca/gear_cutting/template.html http://woodgears.ca/gear/howto.html
A 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.
A 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.
Face gears are the gear wheel with cogs mortised into its face, usually in conjugation with a lantern pinion.
Worm gears resemble screws. A worm gear is usually meshed with a spur gear or a helical gear, which is called the gear, wheel, or worm wheel.
Double helical gears, or herringbone gears, overcome the problem of axial thrust presented by “single” helical gears, by having two sets of teeth that are set in a V shape.
Helical or “dry fixed” gears offer a refinement over spur gears. The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling causes the tooth shape to be a segment of a helix.
This class of gears includes the most common straight and spiral bevel gears as well as miter and hypoid gears.
• External Gears have teeth on the outside surface of the disk or wheel.
• Internal or Annual Gears have teeth on the inside surface of a cylinder.
Rack Gears Defined: a bar or rectangular gear (flat, no curvature) having straight teeth cut on the face, perpendicular to the axis of motion.
