Upon 'hearing' voice messages, an AI robot can write accordingly the Chinese characters like a calligrapher at the exhibition hall of Siasun Robot and Automation Co Ltd in Shenyang, Liaoning province.

"This is one of the achievements where we deeply integrate collaborative robots with artificial intelligence technology," said Han Tianwen, head of Siasun's AI research institute.

"It can engage in voice interactions with people and accurately decipher the emotions or expectations behind the voice initiator through AI large model technology, generating corresponding calligraphy works," he explained.
