iRobot made something similar called the "coworker". It was a spectacular failure. It was shorter and ( i think ) a bit smarter about remote obstacle avoidance. They asked around $5K.

They never answered the question: why is this better than a conference call? This is doubly important considering it has no arms.

I'm certain there is a market for this or a similar kind of robot. It needs to have compelling remote presence, and it needs to be cheaper than $5K.

Adding up motors, computers, cameras, the chassis, plastic modling, etc. can get expensive fast, especially if you haven't ramped up production somewhere fast & cheap like China.
