Main Modes and Programming Methods in Stäubli VAL3+
The Stäubli robots, which operate using the VAL3+ language, can be programmed using several methods - from manually entering commands on the control panel (pendant), through advanced simulation tools, to remote control via a network. This makes the implementation process flexible, safe, and efficient, and NexaRob will help you choose the most suitable programming method. Here are the main methods:
Teach Pendant (Online Programming)
- Direct control: Using a pendant, the operator defines motion points and creates sequences in VAL3+ on a Stäubli robot.
- Quick fixes on the line: Ideal for making small changes or tests without the need for lengthy production downtime.
- Limitations: More complex operations (numerous points, complicated logic) may require considerable time when editing solely on the panel.
Offline Programming (Simulation Environment)
- Working on a computer: VAL3+ code can be designed and tested in a simulation environment (e.g., Stäubli Robotics Suite), allowing you to avoid errors and downtime on the line.
- Time saving: After developing and refining the application in the simulator, simply upload the finished version to the robot, which reduces corrections and shortens downtime.
- Application: Excellent for advanced projects where detailed collision analysis, precise paths, and cycle times are required.
Online Remote Programming (Network Control)
- Remote access: If the network is properly secured, the NexaRob team or operators can connect to the Stäubli controller via the internet and make modifications to the code.
- Expert support: This enables a quick response to errors or optimization needs without the need for an engineer to come on site.
Hybrid Approach
- Combining methods: The Teach Pendant for basic settings and calibration is often combined with offline tools for developing and optimizing more complex functions.
- Gradual improvement: Code can be updated and tested iteratively, minimizing the risk of errors and downtime in production line operations.
Programming methods in VAL3+ are universal and can be flexibly combined, depending on needs and the complexity of the project. This allows Stäubli robots Stäubli integrate with vision systems and sensors, further improving and securing the production process.

- Dynamic motion correction: In applications requiring delicate movements (e.g., connecting electronic components), the robot verifies the force level to avoid crushing or breaking parts.
Force and Moment Sensors
- Precise Assembly: When the torque on an axis exceeds a specified threshold, VAL3+ stops the robot's operation, protecting equipment and operators from dangerous situations.
- Collision detection- Extended kinematics:
Support for Additional Axes and Peripherals
- Enhanced kinematics: The Stäubli robot can control additional axes, such as rotary tables or positioners, and VAL3+ ensures their synchronization during complex assembly or welding tasks.

Automation of Precise Assembly in the Electronics Industry with Stäubli VAL3+
In the electronics industry, where hundreds of thousands of small components must be assembled with the highest accuracy, Stäubli robots - programmed in VAL3+ - have proven to be a reliable and flexible solution. Below we describe a case study in which rapid adaptation to new models and built-in trajectory correction mechanisms made it possible to drastically reduce production time and costs.
Context and Main Challenges
- Delicate Components: Even a small excess of force or deviation in movement would risk damaging the high-value components.
- Multi-stage processes: Each product went through several assembly stations, requiring different levels of precision and force.
- Dynamic assortment: The lines assembled various devices, which required frequent code updates and quick switching between variants.
Solutions in VAL3+ Code
Modular structure of the assembly sequence
Each stage (e.g., feeding components, joining them, visual inspection) was separated into dedicated procedures in VAL3+, which improved readability and facilitated changes to the code. Parameters such as speed, pressing force, or assembly coordinates could be quickly modified in separate configuration files.
Integration with force sensor and vision system
The robot continuously monitored the force level during the assembly of electronic components, protecting them from crushing or cracking. A camera supervised the correct positioning of the components. If any misalignment was detected, the software calculated an offset in real time and corrected the robot’s trajectory.
Automatic quality verification
After assembling each product, the robot performed a short sequence of test movements to check the physical position of key components and signaled any deviations to the operator. The number of devices requiring manual inspection was reduced, shortening the overall production cycle time.
Effects and Benefits
- Increased efficiency by approx. 25% Precise control and error reduction significantly increased production speed.
- Reduced number of defective products Dynamic trajectory correction and force control eliminated component damage, reducing warranty costs and waste.
- Easy Adaptation to New Models: The modular structure and configurable parameters in VAL3+ enabled quick line switching when introducing new device variants.
Thanks to the use of Stäubli robots with VAL3+ proved effective in the demanding electronics environment, where precision and component delicacy requirements are extremely high. Comprehensive support NexaRob - including analysis, coding, testing and training - enabled the investor to improve and accelerate assembly to a degree that translates into noticeable profits and improved quality of final products.
How to maintain high efficiency and compliance with health and safety standards, even with intensive development of applications based on VAL3?
Optimization of Codes and Safety Procedures in Stäubli VAL3+
After creating and implementing an application in the VAL3+ language, it is crucial to regularly improve the code and maintain safety procedures so that Stäubli robots can work efficiently and reliably. NexaRob recommends the following practices that help maintain stability and flexibility of applications:
Cycle time and trajectory analysis
- Data collection: Built-in tools monitor the number of cycles, errors and downtimes. By analyzing these statistics, areas for optimizing trajectories or logic can be identified.
- Refactoring the sequence: Small changes in speed, approach angles, or eliminating unnecessary points can shorten the cycle time without compromising quality.
Code structure and modularity
- Avoiding repetitions: Creating common procedures and functions reduces the risk of errors and facilitates software updates.
- Clear names and comments: Maintaining a consistent naming style (e.g., pMountingPos, nForceLimit) improves code transparency, promoting collaboration among multiple programmers.
Safety procedures
- Emergency stop conditions: VAL3+ allows the robot to react to excessive torque or exceeding safety zones. Regular testing of these functions ensures compliance with health and safety standards.
- Updating in case of changes: When introducing new standards (e.g., automotive, food processing, electronics), it is worth verifying and updating the code and safety sensors.
Updates and development
- New firmware versions: Stäubli often provides software updates and extensions. Assessing their benefits helps decide whether to implement them in a given application.
- Workstation scalability: If a company plans to expand the line with additional robots or devices, the modular approach in VAL3+ simplifies the process of adding new elements.
Systematic code optimization and attention to safety procedures in VAL3+ allow Stäubli robots to operate with maximum efficiency and maintain the highest health and safety standards.
