Telepresence robots have been around for quite some time. They are not cheap though. With Ralph, you can turn your Android device into a telepresence robot. The kit comes with a Husarion CORE2 control and open firmware. You will be able to chat with others over the Internet.
The Ralph robot ships with 2 x DC motors, one servo, and one orientation sensor. You will need 3 rechargeable batteries and an Android smartphone/tablet to get started.
