Collaborative robots can boost your company’s output, increase productivity, and ensure the quality of the products you manufacture. But introducing collaborative robots into your business is a big step, and finding the right cobot for the job is not easy. In an effort to simplify the shopping part of the process, Collaborative Robotics Trends compiled the cobot comparison chart below.
It compares 100 collaborative robots by maximum payload, maximum horizontal reach, repeatability and degrees of freedom. The cobot comparison chart also includes links to each cobot’s website for additional information. Here is a quick definition of the specs we compared:
Payload: The weight the collaborative robot can carry. All collaborative robots have a given payload, which is calculated without the weight of the end effector or robot tool. This means that the real payload that can be carried by the robot is the nominal payload minus the weight of the robot’s end effector.
Horizontal Reach: Reach is the measurement of the distance that can be reached by the collaborative robot’s wrist. This measurement is taken from the robot’s base.
Repeatability: Repeatability is the closeness of agreement between several positions reached by the collaborative robot’s end-effector for the same controlled position, repeated several times under the same conditions.
Degrees of Freedom (DOF): Degrees of freedom, in a mechanics context, are specific, defined modes in which a mechanical device or system can move. The number of degrees of freedom is equal to the total number of independent displacements or aspects of motion.The term is widely used to define the motion capabilities of robots.
All of these collaborative robots are currently available on the market or soon will be. However, these are advertised specs, so you need to make sure the manufacturers can deliver on these promises. Before you make any final purchasing decisions, you should work with your local collaborative robotics integrator.
We will keep this cobot comparison chart updated as models come and go. Click here to view the chart as a PDF. If there is a collaborative robot we should add to the chart, please let us know in the comments.
