Sensors

Robotic sensors are used to estimate a robot's condition and environment. These signals are passed to a controller to enable appropriate behavior. Robots need suitable sensors that help them control themselves.

Triple Axis Accelerometer

The Triple Axis Accelerometer Breakout is a simple Qwiic breakout for the KX134 digital accelerometer from Kionix. The includes a host of features including Freefall detection, Directional Tap, and Double-Tap detection, tilt orientation detection, and more. The KX134 can interface with controllers using both I2C and SPI at high speeds so you can use it in an existing Qwiic chain or on an SPI bus.

Zumo Reflectance Sensor Array

The Zumo reflectance sensor array provides an easy way to add line sensing or edge detection to a Zumo robot. It features six separate reflectance sensors, each consisting of an IR emitter coupled with a phototransistor that responds based on how much emitter light is reflected back to it. The sensor array plugs into the front expansion header of the Zumo shield, which provides it with power and the necessary I/O connections.

The default I/O connections are to pins that are otherwise unused by the Zumo shield, but the sensor module makes it possible to remap these pins or disconnect specific sensors altogether to free up I/O lines. Please see the Zumo Shield user’s guide for detailed information about assembly and use with the Zumo robot.
