Bristlebot
A bristlebot or brushbot is an extremely simple form of walking robot. It is one of the simplest of all mobile robots, both in its function and its construction. As a result of this ease of construction, they have become popular projects at the school science fair level. Operation A bristlebot is a simple, rigid-bodied robot where the lower surface is coated in bristles, like a brush or velvet. The mass of bristles are oriented so that there is an overall inclination to them away from vertical. This is broadly consistent across the robot body, so that it gives a preferred "forward" direction. The robot is driven by vibrating its body. The action of these vibrations through the mass of bristles is to gradually move the robot, in the preferential direction of the bristles. There is some comparison between the vibration of a bristlebot and the lashing of bacterial flagella. Most bristlebots are electrically driven, making use of modern developments in low-mass motors and batteries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walking Robot
Walking (also known as ambulation) is one of the main gaits of terrestrial locomotion among legged animals. Walking is typically slower than running and other gaits. Walking is defined by an 'inverted pendulum' gait in which the body vaults over the stiff limb or limbs with each step. This applies regardless of the usable number of limbs—even arthropods, with six, eight, or more limbs, walk. Difference from running The word ''walk'' is descended from the Old English ''wealcan'' "to roll". In humans and other bipeds, walking is generally distinguished from running in that only one foot at a time leaves contact with the ground and there is a period of double-support. In contrast, running begins when both feet are off the ground with each step. This distinction has the status of a formal requirement in competitive walking events. For quadrupedal species, there are numerous gaits which may be termed walking or running, and distinctions based upon the presence or absence of a ...

Coin Cell
A button cell, watch battery, or coin battery is a small single-cell battery shaped as a squat cylinder typically in diameter and high — resembling a button. Stainless steel usually forms the bottom body and positive terminal of the cell; insulated from it, the metallic top cap forms the negative terminal. Button cells are used to power small portable electronics devices such as wrist watches and pocket calculators. Wider variants are usually called coin cells. Devices using button cells are usually designed around a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge, holding their charge for a long time if not used. Relatively high-power devices such as hearing aids may use a zinc–air battery, which has a much higher capacity for a given size, but dries out after a few weeks even if not used. Button cells are single cells, usually disposable primary cells. Common anode materials are zinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Construction Set
A construction set is a set of standardized pieces that allow for the construction of a variety of different models. The pieces avoid the lead-time of manufacturing custom pieces, and of requiring special training or design time to construct complex systems. This makes them suitable for temporary structures, or for use as children's toys. One very popular brand is Lego. Categories Construction sets can be categorized according to their connection method and geometry: * Struts of variable length that are connected to any point along another strut, and at nodes. ** Tesseract connection points are initially flexible but can be made rigid with the addition of clips. * Struts of fixed but multiple lengths that are connected by nodes are good for building space frames, and often have components that allow full rotational freedom. ** D8h (*228) nodes are used for K'Nex, Tinkertoys, Playskool Pipeworks, Cleversticks and interlocking disks in general. ** D6h nodes are used for int ...

Toy Robot
An entertainment robot is, as the name indicates, a robot that is not made for utilitarian use, as in production or domestic services, but for the sole subjective pleasure of the human. It serves, usually the owner or his housemates, guests or clients. Robotics technologies are applied in many areas of culture and entertainment. Expensive robotics are applied to the creation of narrative environments in commercial venues where servo motors, pneumatics and hydraulic actuators are used to create movement with often preprogrammed responsive behaviors such as in Disneyland's haunted house ride. Entertainment robots can also be seen in the context of media arts where artist have been employing advanced technologies to create environments and artistic expression also utilizing the actuators and sensor to allow their robots to react and change in relation to viewers. Toy robot Relatively cheap, mass-produced entertainment robots are used as mechanical, sometimes interactive, toys whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hexbug
HEXBUG is a brand of infrared and automaton toys developed and distributed by Innovation First International. HEXBUG uses many elements used in BEAM robotics. First piloted in the US through RadioShack, HEXBUG is now sold in most major retail stores. The original Hexbugs are based on six-legged arthropods but now come in several different varieties. The name "HEXBUG" relates to the six-sided packaging it is sold in, rather than to its number of legs. History HEXBUG was founded in 2007 in Greenville, Texas, by Innovation First International, Inc., a company that was founded in 1996 developing small-scale robotic products, mostly for FIRST Robotics Competition. HEXBUG was designed to expand the company's presence in the retail toy market, as well as add to the experience created by VEX Robotics, a subsidiary brand of Innovation First International, Inc. that specializes in robotics built in a fashion similar to Erector Sets, and Rack Solutions, which is an engineering firm that ...

Actuator
An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a control device (controlled by control signal) and a source of energy. The control signal is relatively low energy and may be electric voltage or current, pneumatic, or hydraulic fluid pressure, or even human power. Its main energy source may be an electric current, hydraulic pressure, or pneumatic pressure. The Control device is usually a valve. When it receives a control signal, an actuator responds by converting the source's energy into mechanical motion. In the ''electric'', ''hydraulic'', and ''pneumatic'' sense, it is a form of automation or automatic control. History The history of the pneumatic actuation system and the hydraulic actuation system dates to around the time of World War II (1938). It was first created by Xhiter Anckeleman who used his knowledge of engines and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walker (BEAM)
BEAM robotics (from biology, electronics, aesthetics and mechanics) is a style of robotics that primarily uses simple analogue circuits, such as comparators, instead of a microprocessor in order to produce an unusually simple design. While not as flexible as microprocessor based robotics, BEAM robotics can be robust and efficient in performing the task for which it was designed. BEAM robots may use a set of the analog circuits, mimicking biological neurons, to facilitate the robot's response to its working environment. Mechanisms and principles The basic BEAM principles focus on a stimulus-response based ability within a machine. The underlying mechanism was invented by Mark W. Tilden where the circuit (or a Nv net of Nv neurons) is used to simulate biological neuron behaviours. Some similar research was previously done by Ed Rietman in 'Experiments In Artificial Neural Networks'. Tilden's circuit is often compared to a shift register, but with several important features maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steering
Steering is a system of components, linkages, and other parts that allows a driver to control the direction of the vehicle. Introduction The most conventional steering arrangement allows a driver to turn the front wheels of a vehicle using a hand–operated steering wheel positioned in front of the driver. The steering wheel is attached to a steering column A column or pillar in architecture and structural engineering is a structural element that transmits, through compression, the weight of the structure above to other structural elements below. In other words, a column is a compression member. ..., which is linked to rods, pivots and gears that allow the driver to change the direction of the front wheels. Other arrangements are sometimes found on different types of vehicles; for example, a tiller or rear-wheel steering. Tracked vehicles such as bulldozers and tanks usually employ differential steering, where the tracks are made to move at different speeds or even in ...

Oral-B
Oral-B is an American brand of oral hygiene products, including toothpastes, toothbrushes, electric toothbrushes, and mouthwashes. The brand has been in business since the invention of the Hutson toothbrush in 1950 and in Redwood City, California. History Dr. Robert W. Hutson (1920–2001), owner of a periodontal practice in San Jose, began designing a toothbrush in the 1940s. By 1949, he discovered that thin, round-ended, nylon filaments would be gentle on the gums yet effective for cleaning teeth. Hutson patented a toothbrush in 1950. The application for a design patent for his "Hutson toothbrush" was filed on January 13, 1950, and U.S. Design Patent No. 160,604 was granted on October 24 the same year. In 1958, he was granted a utility patent for a "mouthbrush" having fine, soft, flat-ended nylon bristles, and a similar appearance to the 1950 design. He claimed in his application that this brush was less abrasive to tooth enamel, better for massaging the gums, and more effec ...
