In their generic sense, the number of degrees of freedom corresponds to the number of variables necessary to determine the position of a point in space. In the Cartesian coordinate system, the position is defined by three variables (x, y, z), which become six if we also consider the rotations around the axes, appreciable in the case of three-dimensional entities beginner robotics kit.
In the case of simple manipulators, the degrees of freedom can be limited to six, while they rise considerably in the case of anthropomorphic robots, whose appearance, although stylized, is admittedly inspired by that of man.
In fact, the computation of the degrees of freedom of a robot considers the sum of the degrees of freedom of each of its components . In the case of a humanoid manipulator it is therefore easy to imagine how it is possible to obtain very high values, if we consider that a robotic hand, often the most complex technological element to engineer, can overcome 10 degrees of freedom by itself, since each finger it is composed of several articulated arms.
third generation robot
The third-generation robots are autonomous machines equipped with artificial intelligence systems that allow them to generate autonomy in automatic learning algorithms to verify and, in fact, in an autonomous way their consistency with respect to the operations to be performed in a given environment.
Based on various research and development paths, over the years robotics has spread to very different fields, finding increasingly vertical specialization paths, to the point of deserving specific narratives.
Robotics is currently configured as a technological common denominator that sees the most important manufacturers active in several sectors. The differences are often invisible. Based on similar, if not identical, hardware, today we can find a robotic arm both in the industrial sector and serving cocktails in a trendy bar.
What makes the difference is very often the software component , which determines the way and the autonomy with which the robot will solve the need for each application. The same robotic arm, based on the different instructions received, can in fact prove to be functional in many contexts.
Before the usual application review, scheduled in a few paragraphs, we see how robotics has influenced three reference markets such as healthcare, the ‘ manufacturing industry and domestic applications.
Robots in the medical field
The healthcare sector is characterized by many activities that can be made more efficient by automation. This consideration would be enough to make it a privileged field of action for robotics. Its applications are in fact constantly growing, to the point that medical robotics is starting to make history in itself.
