BrainCo Revo 3 Industrial Dexterous Hand FAQ

Which communication protocols does the Revo 3 support?

The Revo 3 Industrial Dexterous Hand currently supports the Modbus-RTU protocol over RS485.

Revo 3 has 21 built-in motors. What are the power supply recommendations?

Since the Revo 3 integrates 21 independent motors, the instantaneous current can be relatively high under heavy loads or when multiple fingers move simultaneously. We strongly recommend using a stable 24V industrial-grade DC power supply with a power rating of at least 100W to prevent voltage drops that could trigger host processor resets.

How is the latency when controlling 21 motors?

The Revo 3 is optimized at the firmware layer for high-density multi-motor control, with a default baud rate up to 5M (5000000 bps). With high baud rate support, command dispatching and status polling remain responsive and reliable.

Does the Revo 3 support auto-calibration?

Yes, it does. After powering on the Revo 3, you can trigger auto-calibration by short-pressing the back button or sending Modbus register commands. Each finger will execute a home sweep to find the absolute physical limit bounds and establish its absolute zero position.

What are the units for position, velocity, and current control?

The physical quantity definitions are consistent with the BrainCo dexterous hand family:

• Position: 0.1 degree
• Velocity: 1 degree/second
• Current: mA
