Overview

Yahboom's own all-aluminum 12-DOF dog, larger and stronger than the DOGZILLA-Lite, with encoder-equipped bus servos that report position, speed, current and temperature. The S2 adds a lidar and voice module for ROS2 mapping, navigation and voice control. Yahboom's product page now returns 404, so it may be discontinued, and remaining stock is uncertain.
