Inexpensive robots

Types of Inexpensive Robots

Robots are machines programmed to function independently or semi-independently. They are applied in areas ranging from industrial manufacturing to performing household chores. While some robots can cost millions, there is a growing market for inexpensive robots that serve various functions. Inexpensive robots can be categorized into industrial robots, personal robots, and toy robots.

Industrial robots automate manufacturing processes and are essential in today's factories. They mainly consist of robot arms for carrying out tasks like painting, assembly, and welding. The high robot arm models cost hundreds of thousands, but companies looking for affordable options can get models that cost under $10,000. These industrial robots help industries to reduce labor costs, increase production speed, and improve product quality. Manufacturers can now be found using inexpensive robots to automate production processes that were previously done manually.

Industrial robots are mostly large machines designed to operate in factories. However, there is a category of industrial robots known as collaborative robots, or cobots for short. These robots are smaller and work in direct collaboration with human workers. Cobots can be employed in small factories that cannot fully automate production due to budget constraints.

Industrial robots serve many functions and can be integrated into different parts of the production line. They may be programmed to carry out specific tasks such as pick-and-place, packaging, palletizing, or machine tending. Some industrial robots also feature endoscopic tools for jobs like drilling, tapping, or reaming.

Toy robots are mainly used for entertainment but can also be used for education. They come in different designs, from simple to complex. While they are mostly meant for kids, some toy robots can be used by adults or engineers in training. In recent years, there has been a growing trend of using toy robots for educational purposes. Known as STEM robots, they help students learn about programming, engineering, and robotics. STEM robots come in different building styles, such as coding building blocks or snap fits. They can also have different levels of complexity and be used to teach various concepts related to robotics. Coding blocks are meant for students just starting to learn programming, while snap fits require students to have a basic understanding of mechanical assembly.

The third category of robots is personal robots. Unlike toy robots, they are not primarily meant for entertainment. Personal robots perform household chores. Some models clean, while others can mow the lawn or help with simple cooking tasks. Personal robots help to reduce the amount of work people have to do around the house. They are not as sophisticated as industrial robots used in production lines. However, they still feature sensors and cameras to help them navigate sofas, tables, or stairs. Personal robots can be programmed to perform specific tasks and work within a defined space, like the kitchen.

Functions and features of inexpensive robots

As one would expect from a financially accessible robot, these robots are functional and have the following features:

• Affordability: Inexpensive robots are budget-friendly without sacrificing quality and efficacy. They are accessible to a wide spectrum of clients.
• Basic Sensors: In order to detect obstacles and navigate their surroundings, low-cost robots come equipped with basic sensors. Simple robots often employ bump sensors and infrared sensors.
• Simple Control Systems: Low-cost robots frequently have straightforward control systems that enable fundamental mobility and behavior. Some robots might only have remote control, while others might have an integrated control system that allows for autonomous operation. The extensible control systems allow users to customize the robot's behavior.
• Limited Payload Capacity: Inexpensive robots generally have a small payload capacity, which means they can only carry a few cups or a few ounces. These robots usually serve a single task.
• Basic Actuators: Robots typically have basic actuators that allow them to move and manipulate objects. These actuators may include motors or servos that provide movement to joints or wheels.
• Low-cost Materials: These robots are made of low-cost materials such as plastics and aluminum. The materials are easy to assemble, allowing buyers to maintain and repair the robots when necessary.
• Basic Communication Interfaces: These robots have only basic communication interfaces, such as Bluetooth and Wi-Fi. Communication interfaces allow users to control and program the robot. Furthermore, low-cost robots often lack sophisticated communication systems, limiting their ability to connect and interact with other devices.
• Limited Battery Life: Inexpensive robots usually have a limited battery life, which means they can only operate for a few hours. This short battery life limits the robot's productivity.
• Basic Mobility: Basic mobility robots can only move on flat surfaces, while putty-type robots can crawl on uneven surfaces.
• Customization Capabilities: Some low-cost robots offer customization capabilities, allowing users to modify and personalize features, settings, and functionalities to suit their specific needs and preferences. This feature provides a more strategic and tailored robotic experience.
• Limited Warranty and Support: Limited warranty and support include reduced after-sales support and service, which can limit the robot's longevity. This lack of warranty and support can result in an increased cost of ownership due to repairs and maintenance.

How to Choose Inexpensive Robots

When buying cheap robots for business, be sure to choose ones that will suit the specific tasks or activities that the business operates. To do this, the following factors must be considered:

• Tasks Robots Are Expected to Perform

  The primary consideration when choosing a robot is the inherent capability of the robot to perform the required tasks. Thoroughly analyze the tasks or activities that the robot will be expected to perform. Whether it is pick-and-place operations in a warehouse, assembling components in a manufacturing line, delivering items within a facility, or performing routine cleaning tasks. Selecting the right type of robot for the specific tasks is very important. This ensures the maximum productivity and efficiency by the robot.

• Weight Handling Capacity

  [Business] Robots come in various types and sizes. Each designed to handle a specific range of weights and payloads. After determining the tasks the robot will be performing, one must assess the weight and size of the items the robot will be handling. This is because it is important to choose a robot with the right payload capacity and dimensions to suit the required handling needs. In doing so, one ensures that the robot performs its tasks effectively. It also prevents the robot from being damaged due to an excessive load.

• Work Environment

  The environment in which the robot will be operating is a crucial factor to consider. Different robots are optimized for different work environments. Robots meant to work in indoor settings such as factories or warehouses may differ from those intended for outdoor applications. Essentially, one must consider whether the robot will operate on smooth indoor floors or rugged outdoor terrain. Also, take into consideration the fact if the robot will be interacting with people in a crowded workspace or navigating through an isolated field environment. Evaluating the work environment helps in selecting a robot that is suitable and well-adapted to the operational surroundings.

• Robot's Communication and Control Interfaces

  It is important to consider how the robot will be controlled and monitored. Various inexpensive robots offer different modes of communication and control interfaces. These ranges from simple remote controls to sophisticated programming environments. Assessing the required level of control and supervision is essential. This helps in choosing a robot with compatible communication and control options. Ensuring easy integration with existing systems and practices.

• Power Source and Charging Requirements

  Power supply for the robot is one of the major factors to consider when choosing a robot. Different models of inexpensive robots come with different power sources. These power sources range from batteries to wired electricity. Hence, selecting a robot that comes with a readily available power source is important. This, in turn, minimizes downtime and maximizes operational efficiency. Also, take into consideration the robot’s charging requirements. This is to ensure that the batteries are not flat or recharged when the robot will be performing its tasked operations.
