On May 4 in Guangzhou, Guangdong, a young girl deliberately used her foot to block the path of a Unitree humanoid robot while watching it. Instead of activating its obstacle avoidance function, the robot stepped on her foot and knocked off her shoe. Fortunately, the girl was not injured, and the robot did not fall in the crowd.

On June 26, Wang Xingxing, CEO of Unitree Robotics, referred to the incident at the Summer Davos Forum in Tianjin. He pointed out that obstacle avoidance technology remains a challenge, especially in densely populated and complex environments.

Most robots are only equipped with forward-facing obstacle avoidance and struggle to handle omnidirectional obstacles, such as pedestrians suddenly approaching from the side. When encountering obstacles, robots must intelligently choose between bypassing or stopping, but current algorithms are still immature. If a robot moves too quickly, it may collide with people; if too slowly, it loses practical value.

Wang noted that robotics technology is still in its early stages, comparable to the safety issues during the early days of the steam engine, and requires continuous iteration and optimisation.

5月4日，广东广州，一名小女孩在围观宇树人形机器人时，故意用脚阻挡其前行，结果机器人不但没有启用避障功能，反而踩掉了她的鞋子。所幸，小女孩没有被踩伤，机器人也没有在人群中摔倒。

6月26日，宇树科技首席执行官王兴兴在天津夏季达沃斯论坛上提及此事，指出机器人避障技术存在挑战，尤其在人员密集的复杂场景中。多数机器人仅具备前向避障功能，难以应对全向障碍（如行人突然靠近）。机器人在遇到障碍时，需在“绕行”与“停障”间做出智能选择，但当前算法尚不成熟。机器人速度过快可能撞人，过慢则失去实用价值。

王兴兴指出，机器人技术仍处于早期阶段，类似蒸汽机刚出现时的安全问题，需持续迭代优化。
