The first talking robot in space released a video message on Tuesday.
It's the last message before Kirobo, the space-bot, returns to Earth.
He said he's tired after spending over a year at the International Space Station (ISS).
"I hope you'll look up at the sky sometimes and think of me," Kirobo said.
But the robot won't be in space for too much longer - its developers are preparing to bring him back to Earth early next year.
"I won't forget you all. After all, I am a robot!," Kirobo said, waving its hand one last time, before being switched off.
The 34-centimetre-tall (13.4 inches) humanoid was sent to space last August to test human-robot communication with Japanese astronaut Koichi Wakata.
During Wakata's six-month stay on the ISS, the two spent time chatting as well as testing the robot's acrobatic moves in space.
After Wakata's departure in May, the robot was left alone.
Fuminori Kataoka, who manages the team behind Kirobo's conversational functions, said that even robots designed for conversation would feel lonely without a companion.
The creator of the robot, Tomotaka Takahashi, believes Kirobo has brought robots a step closer to becoming people's regular, daily companions.
After a year in space, meanwhile, Kirobo has earned its seat on a flight home.
