Line Following Robotic Vehicle with Walking and Climbing Mechanism The electromechanical device or machine used for various purposes and are controlled & operated with the help of programming techniques is called as a robot. The robots are various types based on their applications such as industrial robots, military robots, space robots, domestic robots, walking robots, climbing robots, and so on. The most advanced robotics projects are being developed for effectively using in various fields for several applications. In this article, let us discuss a special type of robotics projects, namely line following robotic vehicle with walking and climbing mechanism. Robotic Vehicle Robotics Projects for Engineering Students The robotic vehicles are special types of machines designed to move on the ground, in the air, underwater, and in space autonomously without a human on board. These robotic vehicles are controlled and operated by various sensors based control systems. The robotic vehicles are specially designed to use in conditions where human beings are unable to enter such as fire accidents, very high or very low temperatures, etc.,. Line Follower Robot Line Follower Robot The robotic vehicle which moves by following a specific path or line can be termed as a line follower robot. These line follower robots are specially used in industrial applications for special purposes such as transporting various parts or machinery or vehicles (cars, bikes, etc.,) by following the specific line from one point (generating unit) to another point (assembling unit). The normal line following a robotic vehicle with special features such as walking and climbing mechanism is one of the interesting robotics projects for engineering students, which can be used for several applications. Simple steps to design a line follower robot with walking and climbing mechanism are shown below. Step1: Gathering required Components Electrical and Electronic Components The components required for the designing line following a robotic vehicle with walking and climbing mechanism are to be estimated based on robot application. Gather all the electrical and electronic components such as resistors, capacitors, IR transmitters, DC motors, transistors, robot body and photodiodes with appropriate ratings along with other parts such as cardboard, bolts, nuts, aluminum strips, etc., as per requirement. Step2: Analyzing the Circuit for Line Follower Robot Line Following Robotic Vehicle Expandable to Walking and Climbing Robot Block Diagram Primarily design a block diagram of project circuits with various blocks such as a power supply block, IR LED & photodiode block and so on. After gathering components, analyze the circuit design based on working various components used. Then place the components over a solderless breadboard as per circuit diagram using connecting wires for testing the circuit working before assembling the circuit on the PCB. By testing the circuit over solderless breadboard if any changes required in the circuit or ratings of the components, then alternations can be done easily without wasting money & time for replacing components or to alter circuit design. Step3: Assembling and Soldering Components Line Following Robotic Vehicle Expandable to Walking and Climbing Robot Project Thus, after analyzing the circuit design, assemble the components as per the circuit diagram over the PCB. Then, solder the circuit using soldering gun & soldering wire by following proper soldering guidelines. Connect all the parts of the robot properly to form a line follower robot as shown in the above image and glue the parts of the robotic vehicle, if required. Step4: Working of Line Follower Robot The IR transmitter and photodiode are used as a photosensor pair which can be used for detecting the specified path for the movement of the line follower robot while walking & climbing walls. The photosensor pair gives appropriate signals to switch the transistors for driving the motors of the line follower robot. Step5: Line Follower Robotic Vehicle with Walking and Climbing Mechanism There are numerous robotics projects for engineering students in which line follower robotic vehicle with walking and climbing mechanism is an innovative and interesting project to design on your own by using our free eBook to design electronics projects. The application of robotics is rapidly increasing in our day-to-day life for several functions such as industrial applications-moving or lifting heavy products, transporting within a limited area by following specific path, processing, welding, home appliances, autonomous robots, military robots for reducing human involvement & danger, collaborative robots for interacting with human such that for performing several tasks, educational robots, mobile robots and humanoids.
