This robot is represented in the logo above, looking out at the viewer.

  • The ESR-1 robot is a large robot, with a legspan of 48 ft fully extended. However, in it's minimal pose, it can be transported by standard trailer [such as you see in landscaping use] and a pickup truck.
  • It employs 8 legs in a symmetrical arrangement, and can be accessorized with two smaller manipulators for manipulation on site. All the leg parts are identical, reducing spares issues. legs connect to the body with just power and network connections.
  • The ESR-1 robot can operate for extended periods, because it uses an on-board diesel-electric generator for it's power source.
  • It's joints are controlled by individual electric motors and motor controllers, networked to the control processors. The Control processors can update the kinematic model, for failed joints.
  • The robot mimics the tarantula as it's biological inspiration, but includes greater ranges of motion than the spider, allowing it to recover from falls, inversions, etc.
  • All of it's wiring and actuators are internal, reducing fouling opportunities that could trap the robot or damage it's control and power systems. This reduces the chance for loss of the robot or needing to rescue the robot.
  • Because of it's range and the resulting possibility for no line-of-sight, the remote access will include both cellular telephone and WI-FI interfaces. Local operation and setup will also be supported by wired Ethernet interfaces.
  • Capable of transporting a payload of 500 pounds. This is subject to stance, with narrower stances supporting more load. The stances available are based primarily upon terain limitations.

Intended Uses:

  • Search and Rescue - over a large area, such as a national park or remote region. The robot has a payload sufficient to carry a person to safety.
  • Geographic survey - the robot can cover a lot of terain types, allowing survey of a region not readily accessible or too dangerous for people
  • Remote Presence - Robot can take the user to a location, and return video and sound, and allow manipulation or communication.
  • Remote cargo and supply delivery.
