WHAT IS PRECISION ROBOTIC APPLICATION? D Y N A L O G , I N C
Do you need to grab a cup of coffee behind your computer monitor? Nothing compares to the human arm. That’s fine. After carefully grasping it, you flip it over and enjoy. However, there is a problem here. You risk spilling coffee all over the table. Why must you exercise caution? Because, strictly speaking, your arm is responsible for a significant task. Your associate must lift and manoeuvre over the monitor with just the right amount of force, at the right trajectory, and at the right speed to avoid spilling a drop to reach over the monitor, which articulates on multiple axes, both back and forth and rotationally. Additionally, acceleration and deceleration matter when it comes to speed. The coffee splatters everywhere when you too quickly raise the cup or accelerate (jerk en route). You still spill coffee all over the place if you slam the coffee cup down on the desk and accelerate too quickly.
A machine that lifts the coffee cup would be constructed with linear axes operating on vertical and horizontal tracks. The end effector is created and made to raise the coffee cup in the same way each time. With its linear machine, your new appliance will allow you to reach over the monitor the same way every time. Not a lot. Suppose you buy a new desk and no longer need to reach for your coffee. How are you going to manage this contraption you constructed?
This exemplifies the traditional compromises that manufacturers have had to make when it comes to machine automation. Let’s assume you wanted a machine to start at one point and then move onto the next. An articulating-arm robot was used when precise positioning at the endpoints mattered, such as in a pick-and-place material handling operation. A system with linear axes would be used if you needed absolute precision on the path between those endpoints. These systems are more flexible than a robot arm because they can’t get into every corner of a work area and can’t be easily modified for a new purpose. However, the linear axes make them precise. The trade-off gap has narrowed in recent years thanks to robotics technology—advanced methods to make the robot arms themselves have helped close this gap. Integrated software has also contributed to the robot arm’s increased intelligence.
THE EVOLUTION OF ROBOTIC PRECISION For decades, robotic spot welding electrodes have been used by articulating arm robots to pinch the metal and weld it together. The way between each spot weld should be steady, but no one cares if the robot’s position, speed, acceleration, or deceleration varies slightly between welds. The most important thing is where the spot weld is. Think about welding with wire along a straight or curved seam. We care about where that robot way is between the beginning and end focuses. We also care about speed increases and decelerations along the joint. However, the common wire does have some gap tolerances because this is wire welding.
It can deal with some variation. For years, robots have been more cost-effective and accurate enough to handle the process. Not only have the costs of robot arms decreased dramatically over time, but they are also adaptable (allowing for greater reach within the work envelope) and simple to retool for a different purpose. This procedure requires precision and accuracy, depending on the joint geometry. A colourful system with linear drives is sometimes utilized. However, even for these precise tasks, more robots are being used today.
