Parameter Description
1. Motor & DOF Control
The Revo 3 dexterous hand features 21 independent motors, delivering remarkable dexterity and movement resolution. Each motor supports high-precision position, velocity, and current closed-loop feedback control.
2. Control Mode Description
| Mode Value | Control Mode | Detailed Description |
|---|---|---|
| 1 | Position + Time | Move to the target position within the specified duration. If the duration is omitted, it operates at maximum speed. |
| 2 | Position + Speed | Move to the target position at the specified speed limit. If the speed is omitted, it operates at maximum speed. |
| 3 | Speed Control | Move continuously at the target speed until a physical limit is reached or a motor stall occurs. |
| 4 | Current Control | Maintain the target current (torque) continuously until a physical limit is reached or a motor stall occurs. |
3. Connection & Electrical Specifications
The Revo 3 industrial hand communicates and is controlled via a standard RS485 interface. When performing physical wiring, please pay close attention to the following guidelines:
🔌 Power Supply & Bus Security
- Sufficient Power Budget: Since the Revo 3 integrates 21 independent motors, the instantaneous current can be extremely high under heavy loads or when multiple fingers are actively gripping. We highly recommend using a stable 24V DC power supply with a power rating of at least 100W to prevent voltage drops that could trigger host processor resets.
- High-Frequency Bus Impedance: At 5M baud rate, please ensure the RS485 bus uses shielded twisted pair cables and keep the wiring length as short as possible to minimize signal reflection and noise.
