As the industrial robot industry matures, seven-axis robots have become a breakthrough target for many companies and are considered a hallmark of high-end industrial robots. So, what are their advantages compared to the very common six-axis industrial robots?
Currently, conventional six-axis robots can not only pass through the x, y, and z axes, but each axis can also rotate independently. Compared to five-axis robots, the biggest difference between them is that they have an additional axis that can rotate freely.
Seven-axis robots, also known as redundant robots, are more flexible than six-axis robots and can adapt to more special scenarios. They are currently mainly used in the 3C industry.
Compared to six-axis robots, it can solve the kinematic pain points of robots, achieving motion path planning that six-axis robots cannot, especially at the end effector, where its position can be changed. Furthermore, seven-axis robots can achieve joint torque redistribution, utilizing their structure to achieve better dynamic performance. Unlike the uniform force distribution of six-axis robots, seven-axis robots can achieve more rational control of each axis based on algorithms. This structure also increases its fault tolerance; in a traditional six-axis robot, if one axis fails, the entire machine becomes inoperable, while a seven-axis robot can adjust its own parameters to redistribute torque and ensure normal operation.
