Among the interesting robots was the Samsung Ballie.
This is robot was 1st introduced at CES 2020, but now its back and it’s been improved to do a lot more. Samsung has made it more like an AI assistant who can control smart devices, turn lights on and even follow your pet and send you updates on what it’s doing. And it has a built in video projector can help you or entertain you by projecting images and videos on walls or even the ceiling. According to Samsung, Ballie is designed to navigate the home to complete various tasks. In addition to sending video updates of pets or family members to mobile devices when away from home, it play music and answer phone calls. I asked about price and availability and was told neither has been set yet.
