Considered a rethinking of robot painting: let’s talk

Not long ago, I spoke to a gentleman from abroad who is building a really cool little paint robot system. He’s working on his PhD project and he’s trying to perfect this robotic system to basically paint a wall with his robotic arm semi-autonomously. Of course, the robot has to be set up first, but then it basically does all the work on its own until it’s complete.

A few years ago, I had written a semi-serious article on this subject titled; “Give me a paint robot and I will love you forever” and my thinking was to challenge robotic engineers around the world to create a robot that made sense. You see, it’s cute all those dancing robots and things like that that they make in Japan, but I want one that will paint my house on its own. In fact, I suggested that commercial painting contractors would be equally intrigued by something like this.

It seems like my dream of a paint robot is coming true, and I’m not the only one dreaming of a perfect paint job without the job these days. I said to the gentleman abroad: “Okay, I really like your robot there, and yes, I have a lot of ideas on this, mainly in regards to spray patterns, spray tips, and technique when finishing a stroke. horizontal so that the amount of paint hitting the wall is uniform at all points and constant. “

You will see that there is a lot in making a robotic painter match that of a human. Human painters seem to develop quite a bit of “finesse” for this, doing it with talent and skill, through inherent knowledge, wisdom and experience without even realizing it, they seem to be able to spray, slightly turning the wrist at the end of the stroke to get the pattern perfect spraying and delivering just the right amount of paint.

I’d like to see the ability of such a robot to paint murals and intricate designs, as well as just flat surfaces. If you are a fan of art, well what if some of the great paintings from bygone periods could be displayed on giant walls, as a reminder of culture and heritage? Maybe that could get tourists to come back, spend money and also provide jobs?

I find this line of study and robotic technology very important, as painting robots are needed, and what we learn could also help with “washing” robots, which is the industry that I am most familiar with, since it is basically the same challenge, spraying liquid on surfaces, which can be contoured and of various shapes, sizes, angles in 3D, of course we must first paint a perfect 2D design before moving on to 3D or 4D (4D lends itself to the next generation of images holographic and 3D printing objects of surrounding interior and exterior textures).

Here are some thoughts:

The system must literally be able to enter a room, use sensors to judge the texture, the condition of the paint, the natural lighting and determine through a decision matrix what is needed based on the software algorithms, then it must mix paint shades and get started, you also need to know the parameters of the room condition to determine if the old paint needs pre-preparation or if it is flaky it should not be painted over.

Imagine a set of robots driving into a war-torn area, or after a natural disaster, and a set of robots, basically the same technology cleans buildings from a flood, cyclone, typhoon, and then the next set comes in and paints. . ? Perhaps another set sprays quick-drying adhesive, caulk, flooring, etc. We need a robotic painting machine that can paint ceilings, and also dome-shaped ceilings, and objects that have many abrupt changes in texture, shape, and angles. Consider all of this and think about it.
