Touch Sensors are the important components in modern Touch Screen Applications. sensors. My Blocks with Inputs and Outputs. SENSORS Custom wide-angle 1080p chest camera. Basic Ultrasonic Wall Follower. Switches. External USB microphone. 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. The term sensor differs from the term transducer. Intro to Sound Sensor. Brick Buttons as Sensors. Joint angle sensors and force sensors in arm joints. 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). Solution 3a Sensors need to be connected to Sensor ports 1, 2 or 3. Intel RealSense camera. Audio localization array. 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 with simple rotational sliders, touch pads and rotary wheels offer significant advantages for more intuitive user interfaces. The range of applications is count-less and some important ones are Mobile Phones, Tablets, Laptop computers, Cars, Elevators, ATMs, Cameras, etc. Loops. Intro to Color Sensor. Intro to Touch Sensor. the sensor is: Currently Pressed Currently Released Pressed and Released Just Before (Bumped) • When might you use this sensor? In general, a sensor measures an aspect of the environment and produces a proportional electric signal. Intro to Ultrasonic Sensor. Tactile sensors Tactile sensing Robotics abstract In this paper, the authors look at the domain of tactile sensing in the context of Robotics. 2/26/2008 5 Problem 3a Why won’t the light sensor work? Sensors are devices that can sense and measure physical properties of the environment, e.g., temperature, size, weight, luminance, resistance to touch, etc. • 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 Sensor ports Importing Additional LEGO Blocks. Sensors allow robots to become more humanlike; and thus can see, hear, move, and touch. Touch sensors in fingers. Inertial measurement unit (IMU). Basic Line Follower. This is a motor port. Roboticists have had trouble giving robots “vision” because of the complexity of the operations, but for those “blind robots”, touch sensors are used. Moving an Object. – 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. Touch sensors are more convenient and more reliable to use without moving parts. 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 … With these capabilities, robots can execute high-level tasks. Data Wires. The use of touch sensors provides great freedom to the system designer and help in reducing the overall cost of the system. Final Challenge. Sound Block. Without sensors, robots can only accomplish a set of repetitive movements that limit the robot’s ability. In this tutorial, we will learn about Touch Sensors. Common sensors used in robots [1]. Today, almost all user interface is based on touch. Two custom 720p HD cameras (one for each eye). The 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 … Each eye ) Just Before ( Bumped ) • When might you use this sensor use sensor.
