Important

This is community-submitted content. Please feel welcome to submit PRs for additions or corrections.

The iRobot® Create® 3 robot has a JST XH-style connector on its internal Adapter Board which is capable of supplying a maximum of 2 A of current at the current battery voltage (14.4 V nominal).

The iRobot® Create® 3 robot has a USB-C®1 connector implementing a USB 2.0 host capable of 5 V @ 3 A continuous, which can be used to power and communicate with various downstream devices.

Here are some hookup examples for NVIDIA® Jetson™2 computers.

NVIDIA® Jetson Orin Nano™ Developer Kit

Note

Hookup kit

Below lists the content of an example kit that enables mounting Jetson Orin Nano Developer Kit with some sensors like Intel® RealSense™3.

The Jetson Orin Nano™ Developer Kit has a 5.5 mm x 2.5 mm barrel connector jack for power (9 V to 20 V) and a USB-C® port for upstream data.
This can be powered from the unregulated battery port of the Create® 3 adapter board by using a JST-XH female connector to DC barrel plug cable.

NVIDIA® Jetson Xavier NX™ Developer Kit

Note

Hookup kit

Below lists the content of an example kit that enables mounting Jetson Xavier NX Developer Kit with some sensors like Intel® RealSense™3.

The Jetson Xavier NX™ Developer Kit has a 5.5 mm x 2.5 mm barrel connector jack (J16) for power (9 V to 20 V) and a USB Micro B port (J5) for upstream data.
This can be powered from the unregulated battery port of the Create® 3 adapter board by using a JST-XH female connector to DC barrel plug cable.

The data connection is established by using a USB Micro B to USB-C® cable, which requires some software tweaking to allow the communication between the Create® 3 robot and Jetson. See this page.

How to mount

Mount bracket for NVIDIA® Jetson NX-style developer kits

A mount bracket can be used to mount either Jetson Orin Nano™ Developer Kit or Jetson Xavier NX™ Developer Kit on the Create® 3 faceplate or in the cargo bay..

You can 3d print the mount bracket.

Note

  • If you are 3d printing the above mount bracket, use support to support overhang areas.

    Slicing example

  • You need four (4) M3 x 6 mm screws; cap head is suggested.

Printable sensor mount plate

You can 3d-print the sensor mount plate.

To fix the plate at a raised height, you can use M3 spacers like this to allow the sensor to have unobstructed view.

NVIDIA® Jetson Nano™ 2GB

The Jetson Nano™ 2GB has a USB-C® port (J2) for power and a USB Micro B port (J13) for downstream data. This can be connected to the Create 3 robot most simply using a USB-C® hub and two cables -- USB A to Micro B and USB A to USB-C®. Hookup diagram for Jetson Nano™
