Adapter to connect Elfin to Computer still necessary? #31

Closed endu-code closed 2 years ago

endu-code commented 2 years ago

Hi As I have seen in the issue from 2018 (referenced below) the elfin Robot should/can not be connected to ROS over the control Unit. Is this a must, or just a recommendation? Are there ways to use ROS over the control unit?

I also tried to contact the maintainer of the repo over the contact statet on http://wiki.ros.org/Robots/Elfin for other questions I think are not worthy to open an Issue. Is this the current contact for this or should I contact Shenzhen Han's Robot Co. for ROS related questions?

Hi, the Elfin should be connected directly to a computer, without the control box. In this >case, you need such an adapter: Elfin cable adapter.pdf

By the way, there is no need to set IP address for EtherCAT connection.

Hi,

right now the only way to connect to the robot via ROS is to connect the LAN cable from the robot directly to your computer. The control box works mainly to power on (electrify ) the robot.

I recommend you buying a LAN to LAN adapter.

If you have any questions, just post a new Issue. One of the maintainers will try to reply you as soon as possible.

Hi, I was checking this manual for the Elfin robot, and on pages 124 through 128 they mention that you can connect to Elfin robot with two methods: 1) Power the robot with an electric cabinet, and 2) Use external power to power the robot using the LAN-to-LAN adapter.

My question is if I should dismiss the first method mentioned in the manual and buy the LAN adapter. At the moment I'm using the first method and I'm getting the same error as #7.
