	Accelerometer Detects motion, vibration, and angle with respect to gravity.
	Advanced Sensor Interpretation Tired of sensor oscillation? Want higher sensor accuracy? Learn how to make a precision mathematical representation of any sensor.
	Color Sensors Learn how robots 'see' color, and how to build your own color sensors.
	Current Sensor Measure current and power use accurately with a current sensor.
	Digital Compass Detects orientation with respect to Earth's magnetic field.
	Encoder (Slot, Rotary, Linear) Used to determine translation distance, rotational velocity, and/or angle of a moving robot part. Also instructions on how to make your own encoder wheel.
	Infrared Emitter/Detector Emits and detects IR. Can be used for signalling, obstacle avoidance, and color detection.
	Load and Torque Sensors Measure torques and other forces directly for your robot system.
	Mercury Tilt Switch A switch that gives a binary output, depending on the angle with respect to gravity, using mercury.
	Photoresistor Changes resistance with detected light. Can be used for simple robot behaviors, such as obstacle avoidance or photovores.
	Robot Computer Vision Using a digital video camera with highspeed processing to detect the 'real world.'
	SharpIR Rangefinder Detects obstacle range from inches to several meters. Modulated, hence immune to ambient IR.
	Sonar Detects obstacles and can determine object softness/hardness through echolocation.
	Tactile Bumper Switch Detects physical contact, such as for robot collision detection.
