The number of axes a robot has is also called degrees of freedom. A simple industrial robot arm is enough if you have simple tasks like picking up and moving apart from one conveyor to another.

However, if your robot has to operate in a small workspace and its arm needs a lot of mobility. A robot with 6 or 7 axes will be the best option. It is worth noting that the presence of a robot with more degrees of freedom than necessary for a specific task. It is an advantage that allows it to be repurposed and used in more studies.

Working range of an industrial robot

When selecting Equipment, it is necessary to consider the maximum distance the robot must reach to complete the tasks. The maximum vertical reach of the industrial robot arm is measured from the lowest point the robot can go to the full height.

The maximum horizontal reach is the distance from the center of the robot’s base to the farthest point the arm can reach horizontally.

Industrial robot: repeatability and accuracy

The ability of a robot to reach the same position every time it performs the same procedure. For example, if your robot is required to create an electronic circuit board. You may need an industrial robot arm with high repeatability and accuracy. If your task is rather rough, such as palletizing, it makes no sense to overpay for increased accuracy.


As such, there is no single “speed” parameter for robots. Depending on the task, the speed can be linear, angular, expressed in units of repeated actions over some time, and similar values.


The mass of the robot is an essential factor when designing a robotic cell. If an industrial robot must sit on a unique base or rail, its weight must be known to create appropriate support. Suppose the industrial robot arm supposes to move weights. Moreover, it is necessary to add the maximum weight of the object moves to this value.

Presence of brakes

Each robot manufacturer provides information about the braking system of their robot. Some robots have brakes on all axes, while others do not. You need to have enough brakes to have an accurate and repeatable position in the work area.

Industrial robot: torque and inertia

The manufacturer may specify the inertia of specific arm segments for high-precision applications. Moreover, if your maneuver requires a certain amount of torque to complete the job correctly, you must check if the maximum torque applied to the axle is sufficient.

If the limit torque on the axis exceeds, the industrial robot arm will turn off due to overload.

Industrial robot: protection measures

Depending on the working conditions, the Equipment must meet specific standards of protection against external influences in terms of such parameters as security and safety.

In the descriptions and technical documentation, the degree of protection indicates by the IP code (International Protection Marking – international protective marking, standards for the protection of housings from the penetration of liquid and solid substances inside).

Different Marking Procedures of Industrial Robot Arm

Moreover, the marking has the form IP-XX, where the first X means protection against foreign objects (from parts of the human body to dust particles – from 1 to 6), and the second. Protection against water penetration at different exposure times and pressures (from 1 to 9).

If the robot works with food, laboratory, or medical instruments in flammable or corrosive environments, you will need a device that meets specific industry standards.

Industrial robot arm: application cases

Industrial Robot Arm 2022

Wood construction, BEC, and ICD

One of the activities of the Institute for Digital Design and Construction at the University of Stuttgart is robotic production in architecture. Moreover, in collaboration with BEC GmbH, ICD has developed an innovative lightweight wooden pavilion that can only be built with the help of robots.

The build process was as follows:

  1. Robot 1 installs the base on the biaxial positioner;
  2. Robot 2 applies glue to a wood panel;
  3. Similarly, Robot 1 attaches a carrier beam to it;
  4. Robot 2 nails the shaft into place with wooden nails;
  5. Moreover, industrial robot arm 1 glues the additional panel to the glue applied to the post by robot 2;
  6. The cover panel also fixes with nails;
  7. Once the glue has hardened, the robot places the assembled structure back on the DKP-400;
  8. Furthermore, Robot 2 precisely mills corner contours and joints;
  9. Robot 1 mounts the resulting part of the structure.

Multi-Purpose Mobile Robots

TOPSTAR specializes in the production of special machines with different technologies. In its work, the company uses robotic systems installed on a mobile platform.

The TOPSTAR robotic arm has the highest repeatability and precision and can work efficiently in confined spaces. During operation, a light protective fence is installed around the industrial robot arm for safety reasons.

Moreover, the tilt and height of the table can adjust to maintain the patient’s hemodynamics and provide the physician or surgeon with optimal access to the operating area. This is advantageous in long-term interventions, where the surgeon must wear a heavy lead apron.

Industrial robot: Recommended Equipment

A collaborative robot that, thanks to its modular design, even a schoolboy can assemble. Working with it is as easy as using a smartphone. If desired, the operator can manually move the industrial robot arm to the desired position and let it learn the new movement. This direct learning feature allows even inexperienced operators to get the robot to complete the task.

Moreover, one control unit can control two robots simultaneously, reducing the initial cost. The I/O module and the Ether CAT socket on the robot body make it easy to connect various peripheral devices such as a gripper, optical sensor, etc.

Features of the industrial robot arm

Features of robot arm model:

  • Compact dimensions, suitable for equipping even a tiny workplace;
  • Ease of installation and maintenance;
  • Specialized software developed for this series of manipulators – KR c4 compact;
  • Wide scope;
  • Ease of installation and maintenance;
  • Specialized software;
  • High speed of work;
  • Degree of protection IP 54.

The manipulator equips with a new-generation recognition system. This is a compact 6-axis robot that can mount on almost any surface, including ceiling or wall. Moreover, the range of the robot is up to 90 cm, and the load capacity is up to 10 kg, with its weight – 54 kg.
