Autonomous robots are gaining popularity in today’s technological era. Obstacle-avoiding robots are becoming standard components of many equipment and toys, from self-driving vehicles to robot vacuums. An obstacle-avoiding robot is an autonomous robot with the ability to maneuver around barriers. It use sensors to find impediments, and then algorithms to figure out how to get around them. The design, construction, and potential uses of an obstacle-avoiding robot will all be covered in this article.
Definition
An obstacle-avoiding robot is an autonomous robot that can move keeping away from obstacles in its path. It has sensors that helps it detect the barriers and then uses algorithms to determine how to navigate around them. For example, the robot may combine vision, infrared, ultrasonic, or other sensing devices to sense obstacles. Then, it may require algorithms such as path planning or reactive navigation to determine the best route around the obstacle.

The fabrication process for Obstacle Avoiding Robot
The following are the activities to carry out when fabricating the obstacle-avoiding robot:
1. Gathering the Requirements
This step involves deciding what to look for and what to consider before you start connecting your design. These requirements include the project’s aim, the type of robot and components, and needed resources. The robot’s purpose should be simple for a beginning roboticist to understand. The planned functionality of the robot also influences its type and the components required.
2. Assembling the Chassis
Once you have identified the requirements, the next step is to assemble the chassis. This process involves putting together the robot’s body and attaching the necessary components. The chassis should comprise durable materials such as aluminum, wood, or acrylic. If the robot is to depend on motors for movement, please ensure that you have mounted them to the chassis securely.
3. Mount the Components
Mounting the components involves attaching the motors, wheels, and other necessary components to the chassis. You should securely mount and arrange them ergonomically to ease their operation.
4. Preparing the Ultrasonic Sensor
The ultrasonic sensor is an important component of the robot since it detects objects in the robot’s vicinity. Therefore, the sensor should be firm on the circuit board and in a suitable position to detect objects from all directions.
5. Wiring Components
The process involves wiring the components together. First, you connect the motors, wheels, and ultrasonic sensor to the Arduino UNO board. You should also remember to keep your setup neat and organized. A schematic diagram should help you in conducting the wiring of the components.
6. Programming Arduino UNO
Programming the Arduino UNO board involves writing code that will allow the robot to perform its desired tasks. The language of the code should be compatible with the Arduino UNO board.
7. Power the Robot
Finally, you will need to power the robot. This action is easy using a battery or a power supply. The power supply, connected to the Arduino UNO board, helps power the robot. You should also remember to turn on the power before operating the robot.
Note: Once the fabrication process is complete, please test the robot to ensure it is functioning correctly. Also, remember to make any necessary adjustments before using the robot. After the fabrication process is complete, the robot should be ready to perform its desired tasks.
