A company is involved in robotics. One of its robots is designed to make a specific movement depending on a binary value. The table gives some of the movements for the robot. Complete the table by writing the missing binary, denary or hexadecimal value for each movement. Movement Binary Denary Hexadecimal forward 1 step back 1 step 8C turn right 5A turn left Working space Describe what is meant by robotics. The robot has a sensor and a microprocessor. The robot will move forward continuously until it detects an object that is less than or equal to 10 cm in front of it. If an object is less than or equal to 10 cm in front of it, the robot turns 90 degrees right. It then tries to move forward again. Explain how the sensor and the microprocessor are used to automate this robot. The robot needs to find its way through different puzzles. Each puzzle has a series of paths that the robot needs to follow to find its way to the end of the puzzle. The puzzle contains dead ends and obstacles, so the robot needs to decide which way to go. The robot’s program will use artificial intelligence (A. Describe the characteristics of AI. Explain how the program will use AI.

A farmer uses an automated robot to plant seeds in the field. State what is meant by the robot being automated. Give three characteristics of a robot. The robot plants seeds and stops when it reaches a fence. It then turns and continues planting seeds. The robot uses sensors and a microprocessor to know when it reaches a fence. Explain how the robot uses sensors and a microprocessor to know it has reached a fence. Give two advantages of the farmer using an automated robot to plant seeds. Give two disadvantages of the farmer using an automated robot to plant seeds. The robot is adapted to have machine learning capabilities. Explain how this will improve the robot.
