Meet Double by Double Robotics. http://www.doublerobotics.com/

Technology behind is complex and was made simple, using available technology already familiar to mass human market.
Imagine, the is so many creative application that we can use with this technology.
In Malaysia for example, we already have Tesco eshop where you can shop online and have the grocery delivered to your home with a click of mouse.
Tesco may add this Double Robotics in it store where customer may roam their store using this and shop around as if they were there in actual store. Nice right!!
Goverment sector may use this at their front office, client just log in using ipad or computer and interact with government official.
Doctors can have one in their room, patient can consult for medication, doesn't matter from wherever they are.
Lecturers and teachers can also benefit from this technology, providing remote or distance learning.
At the simplest application Double can be guards at our house.
There is so many application open up with this Robots, we just need to use our imagination
At this point of writing, they are only open for pre-order at usd 2499. Quite high for a house guard right.

This is what we do. Beautifully ilustrated in this cartoon
