A five foot tall ROBOT tour guide called Betty will lead visitors around Blenheim Palace

Sir Winston Churchill's birthplace, Blenheim Palace, is experimenting with a five-foot tall robot tour guide, called Betty. The autonomous robot is the latest in a series of tech advances in the grand stately home. Betty is designed to seek out visitors to provide information and answer their questions. It even takes selfies with visitors and can upload them to social media using the Twitter hashtag #bettyinthepalace. New addition: Blenheim Palace's new robotic tour guide wanders the halls of the stately home.
