![]() The obstacle-avoidance system of claim 8, wherein the sensor is positioned to obtain a field of view in the vehicle's direction of travel.ġ1. ![]() The obstacle-avoidance system of claim 8, wherein the sensor is an echolocation sensor.ġ0. An obstacle-avoidance system for augmenting a navigation command in a vehicle, the obstacle-avoidance system comprising: a sensor configured to detect a collision threat and a processor, wherein the processor is communicatively coupled to the sensor and the vehicle's control system, wherein the processor receives an original navigation command from the control system, wherein the processor receives, from the sensor, obstruction data reflecting a position of a collision threat, wherein the processor generates a modified navigation command in view of said obstruction data, wherein the processor outputs the modified navigation command.ĩ. The obstacle-avoidance system of claim 1, wherein the command instructs the vehicle to maintain a predetermined distance between the vehicle and the collision threat.Ĩ. The obstacle-avoidance system of claim 1, wherein the command instructs the vehicle to perform a responsive maneuver.ħ. The obstacle-avoidance system of claim 1, wherein the command overrides the navigation commands.Ħ. The obstacle-avoidance system of claim 1, wherein the command attenuates the navigation commands as a function of the distance between the vehicle and the collision threat.ĥ. The obstacle-avoidance system of claim 1, wherein the processor generates a global environment estimate from said obstruction data.Ĥ. The obstacle-avoidance system of claim 1, wherein the plurality of sensors comprises at least one acoustic sensor.ģ. wherein a bank of algorithms can access the global environment estimate.Ģ. wherein the processor assembles a global environment estimate from the plurality of sensors. A collision-avoidance system for a vehicle, the collision-avoidance system comprising: a communication device a plurality of sensors, the plurality of sensors configured to detect collision threats within a predetermined distance of the vehicle and a processor, wherein the processor is communicatively coupled to the communication device and the plurality of sensors, wherein the processor receives navigation commands being communicated to a control system via said communication device wherein the processor generates, using at least one of said plurality of sensors, obstruction data reflecting the position of a collision threat wherein the processor identifies, using said obstruction data, a flight direction for avoiding said collision threat and wherein the processor outputs, via said communication device, a command to said control system causing the vehicle to travel in said flight direction.
