The military initially considered using Boston Dynamics’ dog-like Spot robot to scare off the intruders, but they quickly realized it wasn’t fast enough to effectively shoo the critters away. Members of BASH have been working with research wildlife biologists for the past five years on the Coyote Rover project. The team’s early tests using the Spot robot failed because the high-tech robot couldn’t charge the pesky wildlifethem at fast enough speeds. In total, the Coyote Rover units reportedly cost between $2,500 and $3,000. For now though, the Coyote Rover unit is limited to scarecrow duty.
