Which robot is Thor?

Excuse me, could you please clarify for me which robot you are referring to as "Thor"? I'm not familiar with any direct association between the name Thor and a specific robot in popular culture or robotics. Are you perhaps thinking of a character from a movie or TV show that involves robots and has a character named Thor? Or is there a specific robotic project or technology that goes by that name? Clarifying the context would help me better understand your question.
