Adding new custom ROBOTIS HAND RH-P12-RN to xARM6

[SOHAILMBS]

Hi, we've been trying to integrate a ROBOTIS gripper RH-P12-RN with a xARM6. Currently, it is connected with the serial port on the end of the xARM6.

We have tried communicating with the RSH-485 port but have been unsuccessful. We followed this example in which some similar grippers like the Yinshi and Robotiq that were controlled via the RSH-485 here but it doesn't seem to work with this gripper.

Any potential solutions or insights into integrating and using this tool would be highly appreciated.

Currently, it looks for a port to open, however, the communication to the gripper is over RSH-485 communication via an ethernet wrapper. So we decided to perhaps send the communication via modbus as in the above example. Maybe you can provide the data frame/ hexa-decimal to control the gripper.

Hi, I'm sorry, this is not an answer that can solve your issue directly.
A Japanese engineer faced with the same issue as you, and he tried to solve it by converting RS485 with STM32.
Look at his tweet. For reference.

Thank your quick reply. I guess we may have to look for a similar solution.
