Question 4 write a one page note on the following robot with diagrams on SCARA robots Answer Dear Reader, Today, I would like to introduce you to the SCARA robot – a widely used industrial robot known for its speed, accuracy, and versatility. SCARA stands for Selective Compliance Assembly Robot Arm and it was developed in the 1980s by Japanese company, Sankyo Seiki. In this note, we will explore the history, working principle, applications, and benefits of SCARA robots. History: As mentioned earlier, SCARA robots were first developed in the 1980s by Sankyo Seiki. The original design of this robot was inspired by the human arm – having a vertical axis and a horizontal axis, resembling the two arms of a human. This design allowed for greater flexibility and a wider range of motion, making it suitable for assembly and pickand-place tasks. Initially, SCARA robots were used in the electronics industry for assembling small electronic components. However, with advancements in technology, they are now used in various industries such as automotive, pharmaceutical, and food and beverage. Working Principle: A SCARA robot has two rotary joints and one linear joint. The first rotary joint allows for rotation of the arm around a vertical axis, while the second rotary joint allows for rotation around a horizontal axis. The linear joint enables the arm to move up and down, similar to a human shoulder. This configuration of joints allows for four degrees of freedom, providing a relatively large workspace. SCARA robots use a combination of stepper motors and servo motors to control the movement of its joints. The stepper motors provide precise and repeatable motion for the rotary joints, while the servo motors are used for the linear joint, providing precise and controlled vertical movement. This highly programmable and precise movement is what makes SCARA robots suitable for a wide range of industrial applications. Applications: SCARA robots are well-known for their speed, accuracy, and repeatability, making them suitable for a variety of tasks such as assembly, pick-and-place, packaging, and materials handling. Due to their compact design and high precision, they are commonly used in the electronics industry for assembling small components such as mobile phones and computer chips. Additionally, they are also used in industries that require high-speed and precise movements, such as food and beverage, pharmaceutical, and automotive industries. In the automotive industry, SCARA robots are used for tasks such as welding, painting, and packaging. They are also used in the pharmaceutical industry for product inspection, packaging, and labeling. In the food and beverage industry, SCARA robots are commonly used for pick-and-place tasks, packaging, and palletizing. Benefits: One of the main benefits of using SCARA robots is their high speed and accuracy. With the precise movements of its joints and advanced control technology, they can perform tasks with a high degree of precision and repeatability, reducing the risk of human error. This not only improves productivity but also ensures consistent quality of the products being produced. Another advantage of SCARA robots is their compact design. The robot’s arms can be easily maneuvered around tight spaces, making them suitable for use in small production areas. This also means that they require less floor space, allowing for a more efficient use of space in a production facility. In addition to this, SCARA robots are also highly versatile. They can be programmed to perform a wide range of tasks, making them suitable for use in various industries. This versatility also allows for quick and easy reprogramming, making it possible for one robot to be used for multiple tasks within a production line. In conclusion, SCARA robots have proven to be a valuable asset in the world of industrial automation – offering speed, precision, and versatility. With advancements in technology, it is expected that SCARA robots will continue to play a significant role in various industries, revolutionizing the way we produce goods and perform manufacturing tasks.

Sincerely, [Your Name] Masters Student in Robotics Question 5 write a code for ardiuno for circuit in which we can open a tap with infrared sensors detect the object make pass a voltage in the circuit make a code in python Answer To create a circuit that utilizes infrared sensors to open a tap, we first need to understand the components involved and their functions. An Arduino board is a popular microcontroller used in many electronic projects. It consists of a microcontroller unit (MCU) which acts as the brain of the circuit, and input and output pins that allow for communication with external components. In this case, the infrared sensors will serve as inputs and the tap will serve as an output. The first step is to gather all necessary materials and equipment. This includes an Arduino board, an infrared sensor module, a relay module, a solenoid valve, and jumper wires. The infrared sensor module consists of two infrared sensors, a transmitter, and a receiver. When an object passes between the two sensors, a signal is sent to the Arduino board indicating that an object has been detected. Next, we need to connect the components according to the circuit diagram. The infrared sensors should be connected to the input pins of the Arduino board, while the relay module should be connected to the output pins. The solenoid valve, which controls the flow of water, should be connected to the relay module. It is important to refer to the datasheets of each component to ensure proper connection and avoid damaging any of the components. Once the physical circuit is complete, we can move on to writing the code. The Arduino integrated development environment (IDE) is a user-friendly platform for writing and uploading code to the Arduino board. The code used in this project will be written in the Python programming language and converted to C++ in the IDE. The first step is to include the necessary libraries for the infrared sensor and the relay module. These libraries provide predefined functions that make it easier to interact with the components. Next, we need to define the input and output pins used in the circuit. This allows the code to refer to these pins by their designated names rather than the physical pin numbers. In the main loop of the code, the output pin of the relay module is set to LOW, which means that it is not receiving any voltage. This keeps the valve closed. The code then checks for any input from the infrared sensors. If an object is detected, the output pin is set to HIGH, allowing voltage to flow to the relay module and subsequently to the solenoid valve. This opens the tap and allows for water to flow.
