How many axes does my robot need?
Manufacturers are incorporating robots into their operations at a significant rate, and given the many benefits that industrial automation has, this is only set to increase. With this growing popularity, industrial robots are available in a huge range of configurations and sizes, with different numbers of axes for a range of applications. Robots can move on anywhere between one and seven axes, with more axes offering more flexibility of movement. However, despite the growing accessibility of robot in industry, it can still be difficult to know which type of robot out of the many now available is the best choice for an application. Traditionally, when someone thinks of an industrial robot, they will picture a robotic arm. These are articulated robots and can mimic the actions of a human arm thanks to their directional control and large range of movement. Other types of robots, such as Cartesian robots or four-axis models such as SCARA robots are more limited, often only able to move on two to four axes. These robots are suited to many applications and certainly have their benefits, but the restrictions on motion can be an issue when more sophisticated movements are required. This is when an articulated robot is a better option. Articulated robots, including six and seven-axis robots, can move vertically and horizontally, but are also able to roll, pitch and yaw —they can rotate around the X, Y and Z axes. This gives them additional range and flexibility. They are typically mounted on a pedestal, with articulation points in the base, body, arm, shoulder, and wrist. This also allows them to work at differing levels and between planes, offering more versatility of motion sequence. Articulated robots are more capable of intricate or complex processes such as automotive assembly due to this ability to accurately manoeuvre. […]
