A solenoid valve is an electromechanically operated valve.The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off;in the case of a three-port valve, the outflow is switched between the two outlet ports.
Caster Wheel is an omni-directional wheel. This wheel can be used as neutral wheel for the robot.
A caster wheel (or castor) is an undriven, single, double, or compound wheel that is designed to be mounted to the bottom of a larger object (the "vehicle") so as to enable that object to be easily moved. They are available in various sizes, and are commonly made of rubber, plastic, nylon, aluminum, or stainless steel. The outer diameter of a caster wheel affects how easy it is for the caster to be able to move across rough or irregular surfaces. Large diameter caster wheels are able to bridge wide gaps where a small caster would fall inside and get stuck, such as the gap in the floor between an elevator door and the elevator car. However, the larger diameter a caster wheel, the higher or wider the caster support arm must be. Either the base of a low-hanging object must be lifted higher above the wheels, or the casters must hang out to the sides straddling the low-hanging supported object. Large diameter swivel casters also typically need much more room to rotate the vertical shaft than a small caster.
Ball transfers can be used for conveyor or caster applications. In the traditional "Ball Up" configuration, ball transfers make an excellent conveying surface. Ball transfers allow for omnidirectional movement across the conveying surface. They are perfect for applications where manual lateral and rotation movement are required. In the "Ball Down" position, ball transfers are a unique caster: a swivel caster without the swivel section. Swivel casters have to orient themselves into position, so off the line you have to put energy into getting the casters in alignment. With a ball transfer caster, the caster is always aligned, as it has omnidirectional rolling. Metal ball transfers are acceptable for use on hard floor surfaces and short pile carpet. Note that metal ball transfers should not be used on hardwood floors.

Agearorcogwheelis arotatingmachinepart having cutteeth, orcogs, which mesh with another toothed part to transmittorque, in most cases with teeth on the one gear being of identical shape, and often also with that shape on the other gear.[1]Two or more gears working in a sequence (train) are called agear trainor, in many cases, atransmission; such gear arrangements can produce amechanical advantagethrough agear ratioand thus may be considered asimple machine. Geared devices can change the speed, torque, and direction of apower source. The most common situation is for a gear to mesh with another gear; however, a gear can also mesh with a linear toothed part, called a rack, thereby producingtranslationinstead of rotation.
The gears in a transmission are analogous to the wheels in a crossed beltpulleysystem. An advantage of gears is that the teeth of a gear prevent slippage.
When two gears mesh, and one gear is bigger than the other (even though the size of the teeth must match), a mechanical advantage is produced, with therotational speedsand the torques of the two gears differing in an inverse relationship.
In transmissions with multiple gear ratiossuch as bicycles, motorcycles, and carsthe term "gear" as in "first gear" refers to a gear ratio rather than an actual physical gear. The term describes similar devices, even when the gear ratio iscontinuousrather thandiscrete, or when the device does not actually contain gears, as in acontinuously variable transmission.
FEATURES:
Aworm driveis agear arrangementin which aworm(which is a gear in the form of ascrew) meshes with aworm gear(which is similar in appearance to aspur gear). The twoelementsare also called theworm screwandworm wheel. The terminology is often confused by imprecise use of the termworm gearto refer to the worm, the worm gear, or the worm drive as a unit.
Like other gear arrangements, a worm drive can reducerotational speedor transmit highertorque. The image shows a section of a gear box with a worm gear driven by a worm. A worm is an example of ascrew, one of the sixsimple machines.
1. A gear consisting of a shaft with a spiral thread that engages with and drives a toothed wheel.
2. The toothed wheel driven in this way.
Worm gears are an old style of gear, and a version of one of the six simple machines. Basically, a worm gear is a screw butted up against what looks like a standard spur gear with slightly angled and curved teeth. It changes the rotational movement by 90 degrees, and the plane of movement also changes due to the position of the worm on the worm wheel (or simply "the wheel"). They are typically comprised of a steel worm and a brass wheel.
Granted, using our muscles to control things is the way that most of us are accustomed to doing it. We push buttons, pull levers, move joysticks but what if we could take the buttons, levers and joysticks out of the equation? Thats right, take the electrical signal straight from the muscle and put it into your device. Thanks to shrinking amplifier technology, we can now do exactly that!
Measuring muscle activity by detecting its electric potential, referred to as electromyography (EMG), has traditionally been used for medical research. However, with the advent of ever shrinking yet more powerful microcontrollers and integrated circuits, EMG circuits and sensors have found their way into all kinds of control systems.
This sensor will measure the filtered and rectified electrical activity of a muscle; outputting 0-Vs Volts depending the amount of activity in the selected muscle, where Vs signifies the voltage of the power source. Its that easy: stick on a few electrodes, read the voltage out and flex some muscles!
This kit comes with everything you need to start sensing muscle activity with your Arduino or controller of choice.

The ever increasing numbers of traffic accidents all over the world are due to diminished drivers vigilance level. Drivers with a diminished vigilance level suffer from a marked decline in their perception; recognition and vehicle control abilities & therefore pose a serious danger to their own lives and the lives of the other people. For this reason, developing systems that actively monitors the drivers level of vigilance and alerting the driver of any insecure driving condition is essential for accident prevention. Many efforts have been reported in the literature for developing an active safety system for reducing the number of automobiles accidents due to reduced vigilance.
Heat shrinkable end caps are typically used to seal cable ends and provide mechanical and environmental protection. When heated in excess of 121C (250F), SKE Heat Shrink Heavy Duty End Caps rapidly shrinks, forcing the melted adhesive lining to flow and cover the substrate. The adhesive forms a flexible bond with a wide variety of rubbers, plastics and metals. Upon cooling, the adhesive solidifies, forming a permanent, non-drying, flexible and water resistant barrier. Adhesive reflow will occur at temperatures above 80C (176F).
FEATURES:
In = 2-24V / Out = 5-28V @ 2A Switching Regulator (Boost = Output Voltage has to be higher than input voltage), Good for getting stable 3.3V or 5V output from 1xAA or 2xAA or Li-ion batteries
Aboost converter(step-up converter) is aDC-to-DC power converterwith an output voltage greater than its input voltage. It is a class ofswitched-mode power supply(SMPS) containing at least two semiconductors (adiodeand atransistor) and at least one energy storage element, acapacitor, inductor, or the two in combination. Filters made of capacitors (sometimes in combination with inductors) are normally added to the output of the converter to reduce output voltage ripple.
The key principle that drives the boost converter is the tendency of aninductorto resist changes in current by creating and destroying a magnetic field. In a boost converter, the output voltage is always higher than the input voltage. A schematic of a boost power stage is shown in Figure 1.
(a) When the switch is closed, electrons flow through the inductor in clockwise direction and the inductor stores some energy by generating a magnetic field. Polarity of the left side of the inductor is positive.
(b) When the switch is opened, current will be reduced as the impedance is higher. The magnetic field previously created will be destroyed to maintain the current towards the load. Thus the polarity will be reversed (means left side of inductor will be negative now). As a result two sources will be in series causing a higher voltage to charge the capacitor through the diode D.

Blood pressure is the pressure of the blood in the arteries as it is pumped around the body by the heart. When your heart beats, it contracts and pushes blood through the arteries to the rest of your body. This force creates pressure on the arteries. Blood pressure is recorded as two numbers the systolic pressure (as the heart beats) over the diastolic pressure (as the heart relaxes between beats). The unit which measures this is calledSphygmomanometer.
Monitoring blood pressure at home is important for many people, especially if you have high blood pressure. Blood pressure does not stay the same all the time. It changes to meet your bodys needs. It is affected by various factors including body position, breathing or emotional state, exercise and sleep. It is best to measure blood pressure when you are relaxed and sitting or lying down. New Digital Wrist Blood Pressure Monitor & Heart Beat Meter Intelligent automatic compression and decompression measure systolic, diastolic and pulse at the same timeEasy to operate, switching button to start measuring.
