A video posted on the Polish Navy's social media accounts showed the Unitree G1 robot, known in Poland as Edward Warchocki, at the naval base in the northwestern city of Świnoujście, near the German border.
The video promoted a naval parade scheduled for Saturday to mark Polish Armed Forces Day.
The incident drew criticism online, with users warning that allowing the robot into a military facility could pose a national security risk.
Critics also pointed out that the navy has used the robot since February despite restrictions on Chinese-made vehicles entering protected military facilities.
The video was removed after several hours.
Asked about the incident, Tomczyk said each such case "requires serious attention."
He said he did not believe "anything particularly bad happened," but added that "someone clearly lacked caution."
Tomczyk said the incident appeared to be "a form of PR and image-building for the military."
He said "the navy spokesman likely wanted to promote the event and present the Polish military and sailors in a positive light."
But Tomczyk also pointed to broader concerns.
"There are much more serious matters related to what China or other countries may undertake against Poland today," he said.
He said restrictions on certain vehicle brands entering military facilities were based on "objective reasons."
"Diligence must be maintained at every level, including the navy spokesman," Tomczyk said.
The Edward Warchocki robot was produced by Unitree, a fast-growing robotics company based in Hangzhou, China.
In March, the robot appeared in the Polish parliament at the invitation of the far-right Confederation party, which said it wanted to highlight the need to adapt Polish law to automation.
The robot later visited several ministries and other public institutions. It also took part in an event organized by the Chinese embassy to showcase Chinese technological achievements and promote contacts with Chinese businesses.

In June, the Pentagon placed Unitree Robotics on a list of companies it said could pose a risk because of their potential involvement in producing dual-use technologies and links to China's defense industry.
