With robot investments typically ranging from tens of thousands to millions of dollars, it’s important to make the right choices the first time and avoid common mistakes that can lead to unnecessary expenses or task delays. To help engineers and designers avoid the worst mistakes, here is a list of the top 10 mistakes to avoid in robotics applications.

Mistake 1: Underestimating payload and inertia

The first mistake of robot application is to underestimate the payload and inertia demand. This is usually caused by not including the weight of the tool at the end of the arm when calculating the load. The second cause of this error is to underestimate or ignore the inertial force generated by the eccentric load.

The inertia force may cause the overload of the robot shaft. In robots, overload of the rotating axis is very common. If this problem is not corrected, it will also cause harm to the robot. Reducing the load or reducing the speed parameter can deal with this situation. However, reducing the speed will increase the cycle time, and as a return on investment, reducing part of the cycle is the first thing to do when it comes to installing robots. This is why load-related elements have been emphasized from the beginning.

The payload is very important, some information given by the ordinary robot technical parameters are detailed, the rated load is effective at the rated speed, and one of the important conditions for reaching the maximum load is to reduce the speed of the robot, in addition, excessive load may also destroy the accuracy of the robot.

Mistake 2: Trying to get robots to do too much

Sometimes, designers ask robots to take on too much work, resulting in robot units that are too complex. Once this occurs, it is difficult to determine the correct cycle time, or it creates difficulties for the disposal solution, which will cause a lot of difficulties due to the handler speed limit. And these mistakes are often magnified, and unplanned shutdowns can lead to huge losses.

Another situation is when the use of robots and work units exceeds the capacity of the original design. When the added work is added after the simulation, it is easy to be disappointed. Especially if no new simulation is done before the plan is advanced, the regular cycle may not be achieved. Therefore, to ensure that the robot’s cycle is within the specified time, it is necessary to pay attention to things beyond the robot’s ability.

Before using the robot, we must go through simulation, according to the design requirements, and confirm the travel load of the robot application, as well as the cycle time.
