BrainCo Revo 2 Common Questions FAQ
The function of the back of the hand buttons.
Long press to restore factory settings, short press for automatic calibration.
Revo 2 Basic version how to switch canfd and the modbus-rtu protocol? Where is the dip switch located?
The dip switch is located below the wrist and requires removing the wrist cover. If switched to the canfd side, it corresponds to the canfd protocol; if switched to the modbus rtu side, it corresponds to the modbus rtu protocol.
Do the Revo 2 Pro and Touch version support EtherCAT CoE and PDO control？
Can support.
Revo 2 Basic version of the dexterous hand has the backlight flashing slowly in green.
The power supply voltage for the basic version of the smart hand is 12-28V. If this issue occurs, it is recommended to increase the voltage to use 24V for power.
Revo 2 Communication frequency
The communication frequency of the second generation hand can exceed 100Hz, the maximum communication frequency of 485/CANfd can reach 500Hz, and EtherCAT can reach 1kHz.
What is the linear measurement range of a capacitive tactile sensor?
Both normal force and tangential force can be achieved 25N，Within the linear range, the fully saturated force is greater than 25N，Linear coefficient 5%。
When using the calibration function, does it only remove the zero offset or also adjust the gain?？
Triggering parameter calibration only ensures that the original values collected by the sensor fall within the usable range, without affecting the offset or gain.
Has internal temperature compensation been applied to the force readings?？
No temperature compensation
Is the returned force value filtered or averaged in the firmware, or is it the raw sample?？
Original sample
What is the internal sampling rate of the tactile sensor?？
Sampling frequency 70 Hz
Current parameters of the Revo2 dexterous hand
Under 24V power supply for the basic version, the standby current is 65 mA, the average no-load current (with five fingers flexing) is 350 mA, and the maximum current is 4.6 A.
For the advanced/tactile version with 24V power supply, the standby current is 115 mA, the no-load average current (five-finger flexing) is 390 mA, and the maximum current is 4.65 A。
What are the units of position, velocity, and current？
Physical quantity position 0.1degree，Speed 1 degrees per second，Electric current mA。
What is a motor sensor? A controller drives six motors？
Using magnetic encoders, one controller drives six motors.
Does the Dexterous Hand have heartbeat messages?
No heartbeat message
485 protocol is half-duplex. Will there be access conflict issues when acquiring data?
485 The bus itself is a half-duplex communication method, and at any given time, only one device can send data.We used standard Modbus RTU Agreement practices in our design ，Using a master-slave architecture, the communication process is entirely controlled by the master station, so there is no issue of access conflicts.
