**E** **AI programs** **Robots** ----------------------------------------------- ---------------------------------------------- **They operate in computer simulated world.** **They operate in real physical world** **The input is symbols.** **The input is analog signal.** **They need computers to operate on.** **They need special hardware with sensors.** **[Exercise 1]** 1. **What is the difference between the Robot System and other AI Programs?** AI Programs Robots **2. Complete the [following:]** 2. **[Complete]** **(1)** Robots are the [artificial agent] acting in the real world environment. **(2)** The robots have [mechanical] form, or shape designed to accomplish a particular task. **(3)** The robots have [electrical components] which power and control the machinery. **(4)** The robots contain some level of [computer program] that determines what, when and how a robot does something. **(5)** [Locomotion] is the mechanism that makes a robot capable of moving in its environment. 3. 1**[Write ( T ) or ( F )]** 5 **3. Write True or False:** **(1)** Legged locomotion consumes more power while demonstrating walk, jump, trot, hop, climb up or down, etc. ( T ) **(2)** Wheeled locomotion comes with the variety of one, two, four, and six legs. If a robot has multiple legs then leg coordination is necessary for locomotion. ( F ) **(3)** Face detection enables us to read the face and take the picture of that perfect expression. (T ) **(4)** In the domain of computers, Optical Character Reader, a software to convert scanned documents into editable text, which accompanies a scanner. ( T) **(5)** Sensors convert energy into movement. ( F) **4. Choose the correct answer:** 4. **[Choose the correct answer]** (Industries -- Military -- Medicine -- Exploration -- Entertainment) **(1)** [Military] Autonomous robots can reach inaccessible and hazardous zones during war. **(2)** [Entertainment] Disney's engineers have created hundreds of robots for movie making. **(3)** [Exploration] The robot rock climbers used for space exploration, underwater drones used for ocean exploration are to name a few. **(4)** [Industries] Robots are used for handling material, cutting, welding, color coating, drilling, polishing, etc. **(5)** [Medicine] The robots are capable of carrying out hundreds of clinical tests simultaneously, rehabilitating permanently disabled people, and performing complex surgeries such as brain tumors. **[Grade 12]** **[Exercise 3]** 1. **[Complete the following.]** **Complete the following:** 1. A sensor is a device that changes a physical [quantity] to an electrical output. 2. An actuator is a device that [converts] an electrical signal to a physical output. 3. An [actuator] is a device that alters the physical quantity as it can cause a mechanical component to move after getting some input from the sensor. 4. There are various types of sensors such as [position], [temperature], [pressure], [speed] sensors. 5. A [sensor] is an electronic instrument that is able to measure the physical quantity and generate a considerate output. 2. **[2) Write (True) or (False).]** 3. **True or False:** **(1)** The sensor is situated at the input port to take the input, whereas an actuator is placed at the output port. ( Trur) **(2)** Robotics actuators are available to measure a wide range of parameters, such as light, temperature, sound, or acceleration. ( False) **(3)** A couple of ways that manipulation can be accomplished are with vacuum grippers or with mechanical grippers. (True ) **(4)** George Devol developed the second industrial robot, Animate. ( False) **(5)** Sensors and Actuators are essential elements of the embedded systems. (True ) **3. Complete the table:** 3. **[Complete the following table.]** COMPAR +-----------------------+-----------------------+-----------------------+ | **Basis of | **Sensors** | **Actuators** | | comparison** | | | +=======================+=======================+=======================+ | **Basic** | **Is a device that | **Is a device that | | | changes a physical | converts an | | | quantity to an | electrical signals to | | | electrical signals** | physical output** | +-----------------------+-----------------------+-----------------------+ | **Placed at** | **Input port** | **output port** | +-----------------------+-----------------------+-----------------------+ | **Outcome** | **Electrical signal** | **Heat or motion** | +-----------------------+-----------------------+-----------------------+ | **Example** | - **Camera** | - **LED** | | | | | | | - **microphone** | - **Motor** | | | | | | | | - **Loud speaker** | +-----------------------+-----------------------+-----------------------+
