Intro to Color Sensor. Touch sensors with simple rotational sliders, touch pads and rotary wheels offer significant advantages for more intuitive user interfaces. In general, a sensor measures an aspect of the environment and produces a proportional electric signal. Sound Block. sensors. Intel RealSense camera. With these capabilities, robots can execute high-level tasks. Two custom 720p HD cameras (one for each eye). SENSORS Custom wide-angle 1080p chest camera. Touch Sensors are the important components in modern Touch Screen Applications. Joint angle sensors and force sensors in arm joints. Importing Additional LEGO Blocks. The sensor is the sophisticated device which measures the physical quantity such as the speed or the pressure and it converts it into the signal which can be measured electrically, The sensors … Audio localization array. Intro to Touch Sensor. This is a motor port. – Useful for programming “moving until touch sensor is pressed/released/bumped” – For example, if you put a touch sensor on the front the robot, you can have it stop moving if it runs into something. External USB microphone. Solution 3a Sensors need to be connected to Sensor ports 1, 2 or 3. Basic Line Follower. 2/26/2008 5 Problem 3a Why won’t the light sensor work? Loops. Basic Ultrasonic Wall Follower. Tactile sensors Tactile sensing Robotics abstract In this paper, the authors look at the domain of tactile sensing in the context of Robotics. the sensor is: Currently Pressed Currently Released Pressed and Released Just Before (Bumped) • When might you use this sensor? The use of touch sensors provides great freedom to the system designer and help in reducing the overall cost of the system. Robots need Robot Sensors to know the world around them, There are many Robot Sensors including ultrasonic, the temperature & the humidity, the force and a lot more to increase the robot awareness .. Touch sensors in fingers. Sensors are devices that can sense and measure physical properties of the environment, e.g., temperature, size, weight, luminance, resistance to touch, etc. The range of applications is count-less and some important ones are Mobile Phones, Tablets, Laptop computers, Cars, Elevators, ATMs, Cameras, etc. Today, almost all user interface is based on touch. In this tutorial, we will learn about Touch Sensors. Without sensors, robots can only accomplish a set of repetitive movements that limit the robot’s ability. Data Wires. The term sensor differs from the term transducer. Moving an Object. Intro to Ultrasonic Sensor. Sensors allow robots to become more humanlike; and thus can see, hear, move, and touch. After a short introduction to support the interest of providing robots with touch, the basic aspects related with tactile sensors, including transduction techniques are revisited. Many Different Types of Robots Snake Robot NXT Robotics Platform NXT Hardware NXT Firmware NXT Software Building LEGO® Pieces Building LEGO® Motors and Sensors Motors Sound Sensor Touch Sensor Light Sensor Ultrasonic Sensor Building LEGO® NXT Sensor Input Ports Motor Output Ports Navigation Buttons LCD Display Screen USB connection socket Lego: Not Just a Toy Rubik’s Cube … Switches. • Sensors constitute the perceptual system of a robot • Sensors are physical devices that measure physical quantities What are sensors • Sensors do not provide state • Examples: – contact -> switch – distance -> ultrasound, radar, infra red – magnetic field -> compass, hall effect My Blocks with Inputs and Outputs. Inertial measurement unit (IMU). Intro to Sound Sensor. Final Challenge. Brick Buttons as Sensors. Sensor ports adapt to disturbances and unpredictable changes in the work environment, the robot needs a variety of sensors, so as to obtain information both about the environment (using external sensors, such as cameras or touch sensors) and about itself (using internal sensors, such as joint encoders or joint torque sensors). The Roboticists have had trouble giving robots “vision” because of the complexity of the operations, but for those “blind robots”, touch sensors are used. Touch sensors are more convenient and more reliable to use without moving parts. Common sensors used in robots [1].
