Do you know what are the application advantages of carbon fibre robotic arms in the new era?

As a moving part, the raw material of the robot arm determines the static dynamic functions of the robot arm. Traditional robot arms are mostly made of light alloys such as aluminum alloy alloy steel, but robot arms made of carbon fiber materials have considerable advantages in terms of specific gravity, creep, strength, cost.

　The weight of the robot arm will affect its own movement speed power consumption. At the same time, it also needs to have good controllability operation accuracy. After all, the robot arm only has to bear its own weight, but also the weight of the grasped workpiece. The density of aluminum, the material used to make traditional robot arms, is 2.7g/cm3, the density of steel is 7.8g/cm3, the density of carbon fiber is only 1.7g/cm3. Boshi has developed a carbon fiber robot arm for a company . The total weight of the robot arm is only 3kg, which is about 50% lighter than that of traditional material robot arms.

　Secondly, the robot arm cannot break strain when bearing loads, which means that the material used to make the robot arm must be strong enough, "high-strength materials" must be selected. Traditional metal materials will cause the arm to bend deform in the vertical plane to twist deform laterally in the horizontal plane due to their own lack of rigidity, the arm will vibrate even cause the workpiece to get stuck. The tensile strength of carbon fiber composite materials is about 1400MPa, which is several times that of steel. It has more advantages than traditional metal materials in terms of elastic modulus load-bearing capacity, is adaptable to high-intensity operating frequencies.

　In addition, an economic perspective, it seems that carbon fiber raw materials are much more expensive than aluminum alloys, but in specific applications, raw materials to molding, the processing cost accounts for a larger proportion of the cost. However, after the efforts of many material people, the price gap between carbon fiber robotic arms traditional aluminum alloy robotic arms has been narrowed. Jiangsu Boshi Carbon Fiber's technical staff has also optimized upgraded carbon fiber robotic arm products, now the price difference between the two can be almost reduced to the same level.
