Nathan Gettings founded Robotex in 2007 and has created a line of robust robots with a team that includes the founders of PayPal and researchers from Stanford's robotics lab. The robots that the company displayed at CES included higher end robots that cops, the military, and corporations use to detect physical, chemical, and security threats. However, the latest line of robots is a BYOD robot, which is cheaper and can be controlled by a smartphone.
The new robot only costs $299. Consumers and small businesses who want home security can stick their iPad on the robot and use another phone to control the robot. The iPad on the robot directly controls it and accepts the commands from the remote iPhone.
Here is a video of the robots that were on display at CES:
