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