Robotics Sensors Quiz: Understanding Level

Types of Sensors

• Environmental monitoring, distance, force, speed, pressure, temperature, magnetic flux, vibration, humidity, rotation, touch, imaging, light, biometrics, gas, acceleration, current, voltage, orientation, gravity, tilt sensing, and speech recognition sensors are available for various projects.

Sensors that Make Signals

• Sensors measure things in the world or control electricity and are called "inputs" because they put electricity into the robot.
• Examples of sensors include infrared, ultrasonic, compass, accelerometer, switch (on/off), and button.

Analog Sensors

• Analog sensors measure things that vary continuously over a range, such as ultrasonic rangefinders and potentiometers.
• Analog sensors can measure in ways that digital sensors can’t, such as light, brightness, and sound.
• Examples of analog sensors include accelerometers, pressure sensors, light sensors, sound sensors, and temperature sensors.
• Analog sensors produce a continuous output signal proportional to the measurand.

Accelerometers

• Accelerometers detect changes in position, velocity, orientation, shock, vibration, and tilt by sensing motion.
• Analog accelerometers produce a constant variable voltage based on the amount of acceleration applied.

Pressure Sensors

• Pressure sensors measure the amount of pressure applied to a sensor.
• Tactile pressure sensors are useful in robotics as they are sensitive to touch, force, and pressure.
• Pressure sensors produce an analog output signal proportional to the amount of applied pressure.

Importance of Sensors in Robotics

• Sensors are used to estimate a robot's condition and environment.
• Sensors measure a physical quantity and convert it into a usable signal for the robot.
• Choosing the correct sensors is important to enable the robot to be aware of its environment and perform tasks required.
• Sensors are based on the functions of human sensory organs.
• Robots require extensive information about their environment to function effectively.
