Introduction

The normal way to connect to your OT-2 is over USB or over Wi-Fi. But if neither of those are working, or if you have more particular networking requirements, you might want to try an Ethernet cable instead.

When you connect to your OT-2 over USB, you're actually secretly connecting to it over Ethernet. Inside the robot, there's a USB-to-Ethernet adapter. This guide will show you how to bypass that adapter, avoiding USB entirely.

Required materials

  • An Ethernet cable

1. Expose the rear electronics

See: Accessing the rear electronics.

2. Unplug the built-in Ethernet cable

Once the electronics are exposed, you should see an Ethernet cable plugged into one of the circuit boards:

A tab on the back of the connector locks it in place. To unplug the connector, you will need to squeeze that tab.

On the back of the robot, there is a hole. Stick a hex driver through the hole to squeeze the tab on the connector. While doing that, use your other hand to pull the cable down and out.

3. Plug in your cable

Now that the Ethernet jack is empty, you can plug in your own cable. Use that to connect your OT-2 to your computer or router.
