Tokyo: Japan's Sony Corp said on Wednesday it has brought back Aibo more than a decade since it last made the robotic dog, as the electronics and entertainment firm seeks to rebuild its reputation for innovation after years of restructuring.

The announcement comes a day after Sony confirmed its renaissance by forecasting its highest-ever profit this financial year, sending its shares surging to a nine-year high.

Aibo is billed as a pet that behaves like a real dog using artificial intelligence (AI) to learn and interact with its owner and surroundings. The upgrade sees Aibo equipped with new sensing and movement technologies as well as far more advanced AI backed by cloud computing to develop the dog's personality.

Sales begin in Japan in January for 198,000 yen ($1,739).

Sony pioneered entertainment robots with Aibo in 1999. It sold about 150,000 dogs in Japan before ceasing production seven years later when its core consumer electronics business struggled in price wars with emerging Asian rivals.

"It was a difficult decision to stop the project in 2006, but we continued development in AI and robotics," Chief Executive Officer Kazuo Hirai said at a news briefing. Reuters
