Patent number: 9789610Abstract: Disclosed herein are methods and systems for determining a safe path for movement of an object by a robotic system. According to these implementations, the robotic system may determine a safety level for each of a plurality of relative orientations of an object. Each such relative orientation may define a spatial orientation of the object relative to direction of movement of the object. Based on the determined safety levels, the robotic system may then determine, for each of the plurality of relative orientations, a velocity limit for movement of the object with a particular relative orientation. Based at least in part on the determined velocity limits, the robotic system may then determine a path for moving the object from a first location to a second location. As such, the robotic system may move the object from the first location to the second location based on the determined path.Type: GrantFiled: September 2, 2015Date of Patent: October 17, 2017Assignee: X Development LLCInventor: Kevin William Watts

Patent number: 9783295Abstract: An unmanned aerial vehicle (UAV) is disclosed that includes a retractable payload delivery system. The payload delivery system can lower a payload to the ground using an assembly that secures the payload during descent and releases the payload upon reaching the ground. The assembly can also include a bystander communication module for generating cues for bystander perception. While the assembly securing the payload is being lowered from the UAV, the bystander communication module can generate an avoidance cue indicating that bystanders should avoid interference with the assembly. The assembly also includes sensors that generate data used, at least in part, to determine when the descending assembly is at or near the ground, at which point the assembly releases the payload. The bystander communication module can then cease the avoidance cue and the UAV can retract the assembly.Type: GrantFiled: March 27, 2017Date of Patent: October 10, 2017Assignee: X Development LLCInventors: Leila Takayama, Matthew Ball, Joanna Cohen, Roger William Graves, Mathias Samuel Fleck, Andrew Lambert, James Ryan Burgess, Paul Richard Komarek, Trevor Shannon
