Core Technology Introduction
SoftForce® Precision Force Control (High-Precision Force Control System), as one of the innovative core technologies of RobustMotion, represents the industry-leading level of high-precision force control systems. This technology utilizes an efficient model predictive control algorithm independently developed by RobustMotion, combined with a high-stiffness force sensor, achieving a control processing frequency of up to 10,000Hz, which means 10,000 calculations per second.Electric actuators equipped with SoftForce® can achieve a force control accuracy of up to ±0.01N (1‰), enabling precise control without overshoot even at high speeds. Through real-time feedback and intelligent adjustment mechanisms, SoftForce® ensures smooth and accurate motion, significantly improving production efficiency and product quality. Moreover, the technology has the advantages of easy integration and maintenance, offering customers a higher cost-performance ratio and lower operational costs.
The flexibility and adaptability of SoftForce® Precision Force Control technology are extremely high, capable of meeting the stringent precision motion control requirements of various industries. It is particularly suitable for ultra-precision assembly, handling, and inspection processes where high precision in force control is required, such as handling high-value or fragile workpieces. Customers can choose the SoftForce® precision force control electric actuator series to meet their specific needs.
In addition, SoftForce® electric actuators can be freely combined into multi-axis precision force control robots, supporting in-depth secondary development, and committed to solving force control challenges in key processes of high-end manufacturing industries.

Industry-leading SoftForce® High-precision Force Control Technology
Softforce® High Precision Force Control
Softforce® Precision Force Control Technology is distinct from the common current loop force control and sensor-based force control solutions found in the market. RobustMotion's independently developed SoftForce®3.0 high-precision force control system (referred to as "SoftForce® Precision Force Control"), has perfectly resolved the traditional conflict between force output and speed. Even under high-speed conditions, the system maintains stable force output with extremely high precision (up to ±0.01N), and can effectively handle impact forces, ensuring "no overshoot" during high-frequency, high-speed motion.

Poor force accuracy and overshoots
Faster - High Speed Response for Better Performance
Actuators can achieve very high precision of force, position, and speed control attributed to their high-speed response system.
Softer - Real-time Force Feedback, High Force Compliance
When dealing with fragile and delicate workpieces, actuators will activate the flexible force control function. When the workpiece is subjected to excessive force, actuators will activate the flexible force control function immediately to reduce the damage caused by overshoot.
High Frequency and High Speed Without Overshoot
Based on SoftForce® 3.0 high precision force hybrid control algorithm, the F/HF series actuators maintain high force accuracy even under high frequency and high speed motion, ensuring "soft landing" and "no overshoot" to protect the workpiece furthest.

Non-damaging Gripping
±0.01N Precision | Adaptive Gripping | Grip Confirmation | Drop Detection
In various manufacturing processes of precision components, the high-precision force control F-Series precision force-controlled electric gripper can be used for gripping fragile and small workpieces. With its built-in adaptive gripping function, RM electric gripper can
grip and transfer full range without considering the size or position of the workpiece or any additional
sensors.
Precise Assembly / Press Fitting / Clamping
Constant Force Control | Force-Position Hybrid Control | Pressure Detection | Zone Signal
In the pressing process, the F/HF Series precision force-controlled actuators can output a constant thrust force rapidly and stably with high flexibility. Even with workpiece tolerances, the precise force can be applied without damaging the workpiece due to overstroke. In addition, the actuator can monitor the quality in real time and inspect the products automatically.
Precise Adhesion
Flexible Force Control | Constant Force Control | Force-Position Relationship Chart
When performing the screen adhesion process for electronic products, the HF Series precision force-controlled linear actuator allows for precise and constant thrust force settings. It switches to precision force-controlled pressing as soon as it comes into contact with the screen, utilizing a flexible force control protection scheme to prevent overstroke damage to the screen. The force-position relationship chart in the RM control software enables real-time monitoring of process quality.
Precise Life/Strength / Passing Rate Testing
Constant Force Control | Push Confirmation | Force-Position Relationship Chart
For example, in the durability testing of terminal insertion and extraction strength, the HF Series precision force-controlled actuator can provide a constant force output. The push confirmation function is utilized to determine if the terminal is properly inserted. Furthermore, it can provide real-time force feedback during extraction, and the force-position curve can be used to assess the quality of the workpiece or product.
Hot Bar
±0.01N Accuracy | Constant Force Control | Force-Position Hybrid Control
For instance, in the precise soldering of PCBs and circuitry, when the soldering iron heats and melts the solder, the RM precision force-controlled linear actuator applies minute and precise force to press the circuitry, achieving high standards of process quality requirements.
Polishing/Precision Grinding of Irregular Surfaces
Flexible Force Control | Constant Force Control
In a reciprocating motion state, the HF Series precision force-controlled actuator employs a unique flexible constant force control method that allows it to adaptively float up and down on irregular surfaces while maintaining a constant force magnitude on the contact surface. For users, it is as simple as setting the positions at both ends and the desired force on the contact surface, and it can be applied immediately.
