Types of homemade robots

A homemade robot is often referred to as a DIY robot. These robots can come in various types, depending on how they were made and what function they serve. Here is a breakdown of some common types of DIY robots and how they work.

• Line Following Robot

  Lines following robots are often built with sophisticated sensors that allow them to track a path marked on the ground. These robots can be built with different types of microcontrollers. For instance, an Arduino robot line follower car can be made using the Arduino motherboard, infrared or color sensors, lines of wheels, and motorized axles. To make these types of robots, a clear line or path with contrasting colors is made on the ground. The robot will then follow the line using its sensors to detect the change in color.

• Obstacle Avoidance Robot

  Just like the name suggests, Obstacle avoidance robots are designed to detect and steer around any obstacles that may be in their path. To make such a robot, the robot is equipped with ultrasonic or infrared sensors that can see or "sense" any obstructions. Once any obstruction is detected, the robot will then change its path to avoid the obstruction.

• Mobile App Controlled DIY Robot

  With advancements in technology, most DIY robots are controlled using mobile apps that have been programmed with Bluetooth or Wi-Fi connectivity. These types of robots enable customers to control the robot's movement from their phones as long as they are within range. To create a mobile app-controlled robot, a mobile phone can be mounted on the robot to act as the brain of the robot. However, the robot should also have a means of connectivity like a Wi-Fi or Bluetooth module. Motors and wheels will also be needed to allow the robot to move.

• Automated Plant Watering Robot

  DIY watering robots are designed to carry out the task of watering plants and gardens automatically. These robots are equipped with moisture sensors that will detect whether the plant or garden is dry. They also have a water pump to dispense water to the plants when they are detected as dry. To make such a Automated Plant Watering Robot, a microcontroller like an Arduino, a water pump, a moisture sensor, and tubing for getting the water to the plants will be required.

Functions and features of homemade robots

Homemade robots are, most times, simple robots designed and built by individuals with limited resources. A key feature of homemade robots is that they allow one to explore the basics of robotic design and functionality. While professional robots tend to be bulky, the homemade robot can be as simple as a small -wheeled or biped robot. When designing a robot, one should keep in mind that the size and shape will vary based on the task the robot will perform. Robots designed to fit in tight spaces will be smaller and more compact than those designed to be larger.

The following features can be found in most homemade robots:

• Microcontroller or processor: This is the brain of the robot. It processes the information needed for the robot to function properly.
• Sensors: Sensors help the robot detect its environment. They help the robot perform tasks according to changes in its environment. A homemade robot can have any of these sensors: light sensors, temperature sensors, ultrasonic distance sensors, touch sensors, or infrared sensors (or simply called obstacles sensors).
• Actuators: These are mechanical devices that allow the robot to perform tasks. They may take the form of motors (DC Motors, Servo Motors, and Stepper Motors) or relays controlling mechanical elements like robotic arms or grippers.
• Power Supply: Depending on the robot's complexity, the homemade robot can run on batteries, AC mains, or even solar power. A robot's power supply system is essential for the robot's uninterrupted function. It provides the required voltage and current for all electronic components, actuators, and motors.
• Chassis: The body of the robot holds all components together. Usually, wheels or legs are attached to the chassis for movement.

Scenarios of homemade robot

The versatility of robots allows them to be used in various industries to make work easier and more efficient. The most commonly used robots are industrial or collaborative robots, which are mostly found in manufacturing plants. Since these robots are expensive, some manufacturers and hobbyists opt to build their own homemade industrial robots for educational and experimental purposes. This helps them learn about the different parts of a robot and how it functions. Some applications of homemade industrial robots are as follows:

• Industrial automation: Industrial robots are usually programmed to perform repetitive tasks with high precision and speed.
• Material handling: These robots use end effectors to pick up different objects and move them from one place to another. They can also stack items and load and unload trucks in factories. The robots are also manufactured with grippers that can clamp, lift, retract, and release objects.
• Machining operations: Robotic arms can be fitted with cutting tools to perform different machining operations such as drilling, grinding, and machining parts and sharp corners that are difficult to reach using conventional tools.
• Welding: Many industrial robots are used for welding metal parts together. They are programmed to follow a precise welding path to make sure the joints are strong and consistent.
• Painting and coating: Industrial robots can be equipped with spray guns to cover large areas with paint or other coatings. This ensures that the coating is applied evenly and reduces overspray.

Some industrial robots have vision systems that allow them to detect and identify objects. These vision-guided robots can inspect parts to check for any defects or damages before they are assembled. They can also pick and place objects with great accuracy. Industrial homemade robots can also be used for educational purposes in schools where students can learn about robot programming, mechanical design, and control systems. They provide a safe and practical way for students to explore robotics, automation technologies, and engineering concepts. By using industrial robots in schools, students will gain valuable hands-on experience and skills that will prepare them for future careers in engineering and robotics.

Homemade robots can be used for research and development purposes to test new technologies and control algorithms. Building a robot from scratch will help one explore and deepen their understanding of robotic systems, sensors, and actuators. The data collected during the experiment can be used to develop and improve existing robotic technologies. This will provide insight into control strategies, sensor fusion techniques, and human-robot interaction.

Ultimately, building and using a homemade robot can be a fun and exciting hobby. It provides a great sense of fulfillment and satisfaction. It can also inspire and motivate others to start their own projects.

How to choose a homemade robot

When buying a homemade robot, one important thing to consider is the skill level. Some build-it-yourself robots require basic skills, while others need advanced skills. For beginners, it is best to start with a robot that requires basic skills and looks for detailed assembly instructions. Detailed assembly instructions are easy to follow for those with no prior building experience. Another thing to consider is the time it takes to build the robot. Some robots take a day to build and play with, while others can take weeks or even months. A robot with estimated assembly time is a good option. It helps people with time planning before buying the kit.

The number of parts in the robot kit is something else that a person may want to think about before buying. Kits with fewer pcs are quicker and easier to build, but those with more pcs have more depth and complexity. They can also provide a more rewarding building experience. The compatibility of the parts is another important thing to consider. Parts compatible with popular hobby and robotics platforms offer greater flexibility. They also allow people to easily use and interchange them with other existing projects and platforms. One more thing to consider is the support and community. Strong support helps builders succeed in their projects. A thriving community of robot builders provides valuable space for sharing ideas, information, and tips.

Finally, before buying a robot kit, one may want to consider the type of robot it is. There are many types of robots, such as wheeled, tracked, biped and hexapod. Biped robots mimic human movements, while hexapod bots have six legs that move like insects. Tracked robots move using tracks like a tank, and wheeled ones use wheels.
