Industrial robots are reprogrammable, versatile, autoregulated gadgets. Unlike in the past when the use of industrial robots was limited to the manufacturing industry, many companies today use them in various operations in the workplace.
Some of the common industrial robot applications are painting, welding, assembly, ironing, palletizing, pick and place, testing, and product inspection. Industrial robots are efficient and exemplify remarkable speed, endurance, and precision.
An industrial robot comes with various characteristics all of which are critical for ultimate robot effectiveness during task execution. The main significant characteristics are precision and repeatability. Precision or accuracy is the contrast between the desired task and the acquired task. Repeatability, on the other hand, is the robot’s capability to execute a similar task repeatedly.
· Evaluating Robot Precision and Repeatability
When it comes to robot precision and repeatability, operators should ensure certain factors are achieved every time the end-effector and the robot are in motion. They are orientation, path, and position.
The integration of orientation and position with the end effector is referred to as a pose. The accuracy of the pose impacts the accuracy path, which due to its ingrained movement is a robust characteristic. Robot repeatability and pose accuracy are divided into orientation and position.
Position accuracy is the robot’s ability to arrive at a certain programmed position with the slightest inaccuracy. It is analyzed in regard to an exclusive reference structure which can be the world reference structure or the work reference structure.
Many times, these reference structures are used to ascertain the position accuracy differences. In order to analyze a robot movement’s static accuracy, position assessments are conducted after the end-effector has completely stopped its movement from the preceding end effector pose.
Analytically, the robot’s position accuracy for each position is the area between the centroid position and the targeted position. The former is the average position of each point of the coordinate direction achieved after the end effector moves repetitively towards the originally targeted position.
Robot position accuracy is the ultimately acquired error applicable to various positions consistently distributed within a pre-planned reference structure or work environment. In this context, repeatability is the proximity of arrangement between various positions arrived at by the end effector for a similar regulated position, repeated under similar conditions several times. Analytically, position repeatability is the slightest sphere’s radius that surrounds each position arrived at for a similar targeted position.
· Industrial Robots for Increasing ROI
Industrial robots have revolutionized the way various companies run their operations. Today, entrepreneurs agree that they have noted significant improvement in their business performance.
Industrial robots are efficient when it comes to fast completion of tasks as compared to manual labor. They also come with a high uptime. The advantage of combined uptime and speed is it increases output while registering low operational costs.
When industrial robots are appropriately programmed, they execute repetitive tasks with ease. This is important in regard to enhancing steady production, reducing waste, and enhancing product quality.
Adopting robots comes with high inaugural costs. However, industrial robots discharge a high return on investment for various companies. Companies that have already embraced industrial robots report increased efficiency, minimized operational costs, and consistency within a short time.
This explains why they have gained massive popularity among numerous manufacturers within the past few years.
Finally
The industrial robot industry has undergone various innovations in the past few years. They come with numerous benefits which are applicable to all types of robotic applications. When industrial robots are well programmed, and adequately aligned to execute the exclusive requirements of a specific application, they are guaranteed to deliver exceptional results in comparison to manual labor. The industrial robot market is growing exponentially and the future can only get better. As technological advancements evolve each day, industrial robots will in future perform more tasks within various industrial applications. While keeping up with the fast-changing world of industrial robots can be difficult, understanding the different types there are in the market and their benefits are critical.
