We had the chance to cover the Giiro Posturebot a short while ago. The project is now live on Kickstarter. It comes with a Giiro mat that you will have to stand on for your posture to be monitored. As the developers explain, the smart mat has 600 sensors.
The robot is perfect for people who stand behind their standing desk for long hours. It uses Alexa to give real-time feedback on your posture. The Giiro bot uses facial expressions to let you know how you are doing. Expected to ship starting May.
