Teaching robots to paint with movements free from the robotic arm with Lesta GESTURE

Teaching robots to paint with movements free from the robotic arm is one of the main requirements for companies that want to automate processes while maintaining precision and quality of the final result. This is where Lesta GESTURE comes in, the system developed by Lesta that captures the operator’s movements during painting and automatically transfers them to an industrial robot.

Thanks to the use of cameras and sensors applied to the spray gun, the system allows the recording of the process in a 3D virtual environment and its replication with extreme fidelity on subsequent pieces in the real world. This solution is designed to improve productivity, reduce programming times, and simplify robotic teaching even in complex production environments.

What are the challenges in industrial painting and how Lesta GESTURE solves them

Many companies operating in industrial painting, especially in the metal sector, face challenges related to process automation. Some of the most common critical issues include:

Limited spaces inside paint booths
Need to maintain high aesthetic quality and coating uniformity
Long and complex programming times for industrial robots
Difficulty in manually replicating complex processes on multiple parts.

Lesta GESTURE was created specifically to overcome these problems. The system records the operator’s natural movement while painting the first part, automatically transforming it into a precise and repeatable robotic path.

The main advantage is the ability to program the robot intuitively, reducing start-up times and simplifying the teaching process, even in production environments with limited space.

How Lesta GESTURE works

The operation of Lesta GESTURE is based on extremely advanced and simple-to-use motion capture technology.

The system uses a joystick mounted under the painting gun, equipped with visual markers detected by dedicated cameras. During the process:

The operator paints the first part using the gun equipped with the joystick.
The cameras track the markers’ movements and transfer them into a 3D virtual environment.
The recorded path is processed and converted into a robotic program.
The industrial robot, such as a KUKA or a Lesta LEBOT DG, automatically replicates the work on subsequent parts.

One of the strengths of the system is that recording is independent of the robotic arm, which allows the operator to move with great freedom and naturalness, improving teaching accuracy and ease of use.

It is important to note that, although this is an extremely effective solution, for some particularly complex or high-performance applications, technologies like Lesta LEBOT MV A6 still represent the most advanced benchmark on the market.

Which companies can use Lesta GESTURE

Lesta GESTURE is particularly suitable for companies operating in industrial painting requiring a flexible and easy-to-integrate automated solution. In particular, it finds application in:

Companies producing medium to large metal components
Powder coating systems
Industrial coating processes for steel
Production facilities with small paint booths
Systems where the installation of more complex robots is difficult.

Thanks to its versatility, this technology allows for improved productivity while maintaining high quality standards, without requiring invasive structural interventions on existing systems.

Innovation and simplicity for robotic painting

With Lesta GESTURE, Lesta introduces a new approach to robotic teaching in industrial painting, combining technological innovation, operational simplicity, and application flexibility.

The system represents an ideal solution for companies that want to approach automation or optimize their production processes, reducing programming times and improving process repeatability.

By transferring the operator’s experience directly to the robot, Lesta GESTURE combines human skills and advanced technology, offering a true competitive advantage in the industrial painting sector.
