The best way to Hall Effect is here. Easily see when the magnet is close to this hall effect sensor with the onboard blue LED. The LED is Solid to indicate it's power and will turn off when the magnet is near.
This Hall Effect is designed specifically for FIRST Robotics Competition teams. You will find this sensor being used as a limit switch in our line of DART Linear Actuators DART, 12" Actuator Kit (am-3072a) and DART, 6" Actuator Kit (am-3076a).
The sensor works with either pole of the magnet and reading the sensor is easy. 5 volts means the component is safe to move 0v means the magnet is under it. You can use two for mounting and two for a cable tie to hold the connecting cable in place.
Connect this sensor to your robot controller using a male PWM cable into the sensor. Black is ground, red is 5 volts, and white is signal.
Compliant wheels are not intended for moving robots, but moving objects. Compliant wheels give way to allow rigid objects to be manipulated easily. A line of multiple wheels on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. This makes for high-performance intakes and internal conveyors. The wheels are sized for an interference fit and tend to stay in place on a shaft, though a shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing.
The hex bore versions of this wheel are undersized, and are intended to be an interference fit on their respective hex shafts. This interference fit allows for effective torque transfer from the hex shaft to the wheel, as well as allowing the wheel to remain in place along the shaft without the need for spacers or collar clamps:
Different durometer ratings give each wheel unique characteristics. Green wheels (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. The increased firmness also allows the latter wheels to carry a higher RPM rating. Check out the downloads tab for a chart showing wheels and their maximum RPM.
