|---|---|---|---|
| Torque Range | 2-50 Nm (rotary) | 50-500 Nm (rotary) | 5-100 Nm (rotary equiv.) |
| Force Range (linear) | 200-2000N | 1000-20000N | 200-3000N |
| Response Time | 5-20ms | 20-50ms | 30-100ms |
| Position Accuracy | ±0.05° (encoder) | ±0.5° (potentiometer) | ±2-5° (flow control) |
| Noise Level | 35-45 dB | 50-65 dB (pump) | 55-70 dB (exhaust) |
| Power Consumption | 50-300W per axis | 500-2000W (pump) | 200-800W (compressor) |
| Maintenance Interval | 10,000 hours | 2,000-3,000 hours | 3,000-5,000 hours |
| Unit Cost (per axis) | $200-$800 | $400-$1,500 | $80-$300 |
Application Selection Guide
| Application | Recommended Actuator | Rationale |
|---|---|---|
| Facial expressions, eye blink | Micro Servo | Precision, silence, compact size |
| Head/neck movement (small models) | Servo Electric | Smooth motion, programmable profiles |
| Jaw bite (large models) | Hydraulic | High force for realistic bite simulation |
| Tail sweep, body sway | Pneumatic | Cost-effective for large-amplitude motion |
| Breathing animation | Pneumatic | Natural compliance, simple control |
ZGDino Hybrid Approach
ZGDino frequently employs hybrid actuator systems that combine technologies within a single unit: servo for precision joints, pneumatic for gross body movement, and hydraulic for high-force applications. This optimizes cost, performance, and reliability.
ZGDino's multi-technology actuator expertise enables optimal motion system selection for every animatronic dinosaur application.
