JetBot — NVIDIA Jetson AI Rover

JetBot is an open-source AI robot platform built on the NVIDIA Jetson Nano. It combines a small two-wheeled chassis with a Jetson Nano compute module, a wide-angle camera, and the full NVIDIA JetPack SDK — enabling object following, collision avoidance, and road-following using convolutional neural networks trained with Jupyter notebooks.

JetBot is NVIDIA's official introductory robotics platform, making it one of the most well-documented and widely-built AI robots for beginners and educators.

Note: The original Jetson Nano is end-of-life / discontinued. New builders should target the Jetson Orin Nano instead — verify JetPack and software compatibility before purchasing, as some JetBot tutorials and libraries are written for the original Nano and may require updates.

What It Can Do

• Object following — tracks a sport ball or colored object using a CNN trained in-browser with Jupyter
• Collision avoidance — learns to navigate around obstacles via a head-mounted classifier
• Road following — stays on a track by regressing a steering angle from a front camera
• Teleoperation — browser gamepad control via the interactive widget interface

Printing

This Print All set maps 1:1 to the upstream NVIDIA-AI-IOT/jetbot assets/ folder. A complete JetBot needs 4 printed parts: the chassis, the camera mount, and one caster base + one matching caster shroud.

Caster size — pick one matched pair (do not print all four). JetBot ships in two caster sizes: 60 mm and 65 mm. Choose the size that matches the caster ball/wheel in your kit, and print the base + shroud of the same size together. Mixing a 60 mm base with a 65 mm shroud will not fit. The list intentionally keeps both sizes so either kit works — a blind “Print All” would produce 2 unused parts.

There is no upstream-designated default size, so the choice depends on your hardware. If unsure, the 65 mm caster is the more common in recent JetBot kits.
