Introduction
Industrial Robot Force Control Technology System Architecture
This standard constructs a complete technical framework including force/torque sensor selection, control strategy classification, and application scenario design. Its core parameter requirements are as follows:
| Technical parameters | Typical indicators | Test methods |
|---|---|---|
| Force control accuracy | ≤1% of range | GB/T 28854-2012 7.4.5 |
| Response period | 1-10ms | Control signal step test |
| Overload capacity | 150%-300% | JB/T 7483-2005 |
Evolution analysis of force control strategies
The standard systematically divides the two major technical routes of indirect force control and direct force control for the first time:
- Classic control stage (1990-2010): Passive adaptive technology represented by impedance control and stiffness control
- Intelligent control stage (2010-present): Fusion application of AI algorithms such as neural networks and fuzzy control
Typical case: In a polishing scenario of an automotive component, indirect force control is used.
| Sensor type | Insulation resistance | Temperature range |
|---|---|---|
| Resistive strain gauge | ≥500MΩ | -30~85℃ |
| Piezoelectric | ≥10¹³Ω | -20~125℃ |
Safety implementation recommendations
Special requirements for collaborative robot scenarios:
- Contact surface curvature radius ≥ 5mm (GB/T 36008-2018)
- Single-point contact force ≤ 140N (human pain threshold)
- Emergency stop response time < 50ms
