Which to choose

Frequently asked questions
Can I switch later?
Yes. Unitree’s SDK and ROS 2 support are consistent across the lineup, so code and workflows move up the range as needs grow.
Is the cheaper one “enough”?
Often yes for trials and light indoor work; rarely for industrial or all-weather duty where ruggedness is the point.
