Dealing with Motor Noise of a Robot 51064

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.

What is the BASIC STAMP ?  51060

What is the BASIC STAMP ? 51060

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.

What is a Microcontroller ? 51059

What is a Microcontroller ? 51059

Anywhere you would like to add intelligence you use a Microcontroller…

microcontroller (sometimes abbreviated µCuC 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.

What is Handy Board ? 51058

The Handy Board is a 6811-based microcontroller system that lets you build mobile robots for educational, hobbyist, and industrial purposes.

Stepper Motors 51056

Stepper Motors 51056

What is a Stepper Motor ?

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.

Gear Motors 51055

Gear Motors 51055

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.

Brushless DC Electric Motors 51054

Brushless DC Electric Motors 51054

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.

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 – HELICAL Gears – 51036

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.
