Toshiba has unveiled its newest robot, Aiko Chihira, a humanoid that can communicate using sign language. The “communication android” is remarkably fluid, using 47 actuators in its joints to speak Japanese Sign Language. Aiko Chihira is still in its developmental stage, and can only mimic simple greetings, but by 2020, Toshiba plans on having a full communication robot who will be able to perform speech synthesis, speech recognition, robotic control, and other features. Ultimately, the Aiko Chihira can be used as a caretaker for elderly and dementia patients. To watch how the Aiko Chihira works, click on the video above.
