1. Basic concepts and classification of robotic arms
A robotic arm is an automated device, usually composed of multiple joints and actuators, that can imitate the movements of the human hand to perform various tasks. The classification of robotic arms mainly depends on their application fields and structural characteristics. The following are some common classifications of robotic arms:
Industrial robotic arms: Industrial robotic arms play a key role in the manufacturing industry. They often have multiple degrees of freedom, allowing them to perform highly complex tasks in three dimensions. For example, robotic arms in the automobile manufacturing industry are used to automatically assemble automobile parts, such as welding car bodies, installing tires, and painting car bodies. These robotic arms must be highly precise to ensure consistent quality.
Service robot arm: Service robot arm is widely used in medical, hotel and catering and other fields. For example, surgical assistance robots such as the da Vinci surgical robot can help surgeons perform minimally invasive surgeries, providing smaller wounds and faster recovery. In the restaurant industry, robotic arms can be used to prepare burgers, pizza and coffee, providing fast and consistent service.
Agricultural robotic arms: Agricultural robotic arms are improving the efficiency of agricultural production. For example, automated harvesting robots can automatically harvest fruits, reducing labor costs and picking time. In addition, some agricultural robotic arms are used for precise fertilization and irrigation to increase crop yields.
Aerospace robotic arm: Aerospace robotic arm is usually installed on a spacecraft and used to perform space missions. For example, the Canadarm on the International Space Station is a mobile robotic arm used to repair and load equipment. In addition, the probes and landers are also equipped with robotic arms for sample collection and scientific research.
2. Application fields of robotic arms
Robotic arms are widely used in various fields, improving production efficiency, reducing labor costs, and improving the working environment. Here are some applications of robotic arms in different industries:
Manufacturing: Robotic arms play a vital role in the manufacturing industry. They are used in automobile manufacturing to perform body welding, paint application and assembly of parts. In electronics manufacturing, robotic arms are used in semiconductor manufacturing, electronics assembly, and quality inspection.
Healthcare: The use of robotic arms in healthcare continues to expand. Surgical robots help surgeons perform precise procedures such as heart surgery and tumor removal. Medication dispensing robots are used to automatically dispense medication doses, reducing medication administration errors.
Logistics and Warehousing: Robotic arms are used in warehouses and logistics for cargo handling, sorting and stacking. Automated shelf systems can quickly retrieve items and improve the efficiency of inventory management. Goods sorting robots are used in distribution centers to sort goods for quick shipment.
Agriculture: Agricultural robotic arms help increase crop yields. Automated harvesting robots can automatically pick fruits, reducing labor requirements and picking time. Some precision agricultural robotic arms are used to apply fertilizers, spray pesticides and irrigate to improve the quality of crops.
Aerospace: Aerospace robotic arms play a key role in space missions. For example, the Canadarm on the International Space Station is used for maintenance and loading equipment to ensure the normal operation of the space station. The robotic arms on the probe and lander are used to collect samples and conduct scientific research.
3. Technological innovation and future trends
The robotic arm industry is constantly developing and innovating. Here are some important aspects about technological innovations and future trends:
Artificial Intelligence and Machine Learning: Robotic arms are increasingly incorporating artificial intelligence and machine learning technologies, allowing them to adapt to changing tasks and environments. For example, some industrial robot arms can learn new assembly processes to adapt to the production of new products.
Collaborative robots: Collaborative robots are a new trend that enable them to work safely alongside humans. These robotic arms are often equipped with sensors that detect humans around them and automatically stop their movement in case of a collision. This increases efficiency and flexibility in the workplace, for example, in medical surgeries where robots can work closely with surgeons.
Sensing Technology: Advanced sensing technology allows robotic arms to sense and adapt to their surroundings. Sensors such as vision systems, lidar and force sensors help robotic arms identify the position and shape of objects to perform more complex tasks. For example, an industrial robotic arm can use a vision system to inspect and handle parts of different sizes and shapes.
Sustainability: Robotic arm manufacturers are increasingly focusing on sustainability. They strive to reduce energy consumption and environmental impact. Some robotic arms employ more energy-efficient drive systems, while others explore ways to recycle energy, such as solar charging systems. This helps reduce the carbon footprint of manufacturing and operations while driving the development of green technologies.
