Robotic arms controlled by Arduino are available in several types, and each is required for other operations depending on the industry, precision needed, and payload capacity. Below are some types of robotic arms based on common categorization.
SCARA
Selective Compliance Assembly Robot Arm SCARA robots have अपनीs horizontal movement capabilities and are flexible when it comes to their joints. This makes them ideal for manufacturing processes like fast assembly picking and placing products and simple welding tasks.)
Articulated Robots
This format resembles the human arm in structure and is known for its joints. All these robots are generally used in more complex and heavy-duty processes, including welding painting, and other such activities. The main advantage of an articulated robotic arm is that it can work in multiple axes and thus has more flexibility.
Cylindrical Robots
A cylindrical robot has one robotic arm that can rotate around a base and have a cylindrical-shaped working envelope. Even though the structure does not resemble human joints, the end joint of the arm will have a prismatic joint. These types of robotic arms are preferentially used in the operations where radial motions, such as pistol drilling or material guarding, are more important than axial movements, such as lifting or lowering objects.
Spherical Robots
The difference between the previous robot arms and this type is that the spherical robotic arms are constructed to perform both radial and axial motions. This movement enables the robot to reach more complex positions compared to those obtainable by cylindrical and jointed robots. Therefore, spherical robotic arms are suitable for applications such as material handling and automated assembly.
Delta Robots
Delta robots have a spider-like structure and are very fast. Because of their speed and precision, these robots are almost exclusively used in high-speed applications like food packaging, electronic component assembly, and other such activities requiring quick and precise manipulation.)
Open-Loop Controlled Robotic Arms
The do-it-yourself robotic arm is cheap and easy to make, needs an Arduino board for making an open-loop-controlled robotic arm, and allows you to easily make it at home. This control system makes it easy to make the arm because it's simple. It doesn't have feedback systems that track the movements or the position of the joints, so it's basically great for simple or basic exercises that don't need extreme accuracy, like few picks and places needed. Because of this characteristic, these types of arms are used in simple tasks.
Closed-Loop Controlled Robotic Arms
Closed-loop controlled robotic arms are more complex and expensive than their open-loop counterparts since they utilize feedback mechanisms to control the positional accuracy of the joints to enhance their operation's accuracy and reliability. Closed-loop control is perfect for applications needing high precision, such as surgery, circuit board assembly, or any other activity that requires careful manipulation of the components.)
Remote-Controlled Robotic Arm
Allowing a human operator to control a robotic arm from a distance using a remote control system, our robotic arms are operated at average levels through teleoperation and are widely used in environments that are hazardous to human beings or spaces that are hard for humans to traverse. Nuclear facilities, space exploration, and deep-sea research are some operations that apply this kind of robotic arm.
The durability of Arduino-controlled robotic arms is, therefore, essential for ensuring reliable performance across various applications, which depends on the materials used in their construction and the specific tasks they are designed to perform.
Metal alloys, especially aluminum and steel, are common materials for robotic arms since they provide a good balance between strength and lightweight construction. Aluminum, with all the allowances for corrosion resistance, is mostly applied where the robot has to be functioning in an open environment with high temperatures or humidity; for example, paintwork, surgical operations, and assembling electronic boards. Steel is more effective for those tasks that require a lot of force, such as welding or manipulating heavy objects, so it is usually found in hostile environments.
In situations where weight is more critical than the strength of the structure, high-strength plastics, such as ABS or polycarbonates, are used to make the body of the robots. 3D printing technology also makes plastics feel like they can be used to make housings for motors and gears. While these materials are very tough, they are also much cheaper and lighter in weight, making them perfect for use in consumer applications and intermediate research.
For robotic arms where the operator demands very high strength but light weight, carbon fiber composites provide these features. Due to its properties, it is less likely to fracture or bend even when subjected to very high-stress levels. While these materials are substantially more expensive, they are preferred in the aerospace and robotic arms for great accuracy, where less weight is a huge bonus. The aforementioned properties account for their huge applicability in the aerospace and precision robotics domains, where less weight is a huge bonus.
Stainless steel is used in robotic arms that operate in corrosive environments such as underwater or in chemical processing. This metal's resistance to corrosion and oxidation makes it perfect for use in such situations. These materials ensure the longevity and dependability of robotic arms even under harsh circumstances and for demanding workloads.
Elastomers, including high-grade rubber, give flexible joints in robotic arms. These durable materials allow the robotic arm joints to easily bend and move without breaking, ensuring that human-like motions are accurately replicated. The flexibility and durability of these materials enable reliable operations in environments that demand deformation, such as automated assembly and surgeries.

One needs to consider several parameters, including the application's requirements, the arm's accuracy and load capabilities, construction materials, and budget.
Application Requirements
The use of the robotic arm dictates the sort of arm that will be used. The robotic arms can be controlled with Arduino for these mundane pick-and-place tasks. The SCARA robotic arms will do just fine, given that the homework involves light work. However, suppose the tasks involve processing under high temperatures, such as welding. In that case, an articulated robotic arm made of metal alloys would be the most appropriate for these tasks. Understanding the nature and requirements of the intended tasks will guide the selection of the appropriate robotic arm.
Precision & Flexibility
The degree of accuracy and flexibility is another important criterion. End-effectors such as grippers and suction cups are mounted on flexible arms, while low-tension cutters, welders, painting tools, and others are attached to rigid arms. For tasks such as circuit board assembly or surgery, precision will be critical, while for more general industrial applications, flexibility may be more important in a robotic arm.
Load Capacity
How much weight the arm can carry has to be taken into consideration. It ensures the arm can handle the weight of the tools or materials used in the task without any damage. For heavy-duty industries like construction, welding, etc., an articulated robotic arm has to be made with metal alloys or carbon fibre for high load-bearing capacity.
Durability & Materials
The robotic arms are controlled by Arduino, so the endurance of the arms can be attributed to the materials used in constructing the arms, i.e., metals, carbon fiber, or high-strength plastics. A durable arm is excellent for the easiest task in this world and specifically designed for hostile environments. Understand where the robotic arm will operate and what environmental conditions it will face to grasp the concept of material durability.
Budget
Robotic arms controlled by Arduino fit into different budgets, ranging from granted easy arms built by the open loop to complex close loop arms. The main stage limitations here are the complexity of the robotic arm design and the materials used in the arms' construction. Set up your target price for the robotic arm and the irrelevant factors that will ensure you do not go over budget without eliminating key features.
