Helen Greiner left iRobot four years ago to start a new robotics company now called CyPhy Works. Their website has info on two of the robots they have been working on.

• The Extreme Access System for Entry (EASE) (pictured above)is a small hovering robot designed for inspection and ISR (intelligence, surveillance, and reconnaissance) applications. EASE is intended for operating in close quarters, beyond line of sight, and in GPS denied areas; all of which are critical when performing search and rescue missions, building clearing, or civil infrastructure inspection.
  
  The EASE system consists of a lightweight ground control station (GCS) and a micro Vertical Takeoff and Land (VTOL) air vehicle. It is not dependent on a GPS signal for operation, making it not only effective as a micro UAS in the traditional sense, but also enables it to fly indoors and in confined spaces as effectively as it does in open spaces. It has unmatched endurance due to our patented microfilament technology that enables the use of hot-swappable batteries, which power the entire system from the base station. The fishing-line thin microfilament provides directly connected communication between the GCS and the air vehicle, as well as power. Unlike all other RF controlled UASs, the microfilament makes the EASE impervious to jamming while the microfilament is unaffected by water, power lines, etc. 

• ​The Persistent Aerial Reconnaissance and Communications (PARC) system is designed to provide long term persistent stare capabilities and enable reliable long distance communications. PARC uses CyPhy Works' patented microfilament system to deliver extreme endurance, increased capabilities, and a smaller logistical footprint. PARC flies itself, so very little user training is required; and when operating the system the user can focus on the data that PARC produces, instead of the system itself.
  
  The PARC system consists of a Ground Control Station (GCS) and a purpose built quadrotor VTOL air vehicle. The PARC vehicle carries a gyro-stabilized, gimbal mounted, EO/IR camera payload. In addition to the camera system, PARC has additional payload capacity for communications devices. If additional payload capacity is required, the camera payload can be removed. The PARC vehicle can operate at altitudes of up to 1,000 feet above ground level, or 11,000 feet density altitude. This high altitude capability enables long distance communications and extends visual reach.
