Packable modular quadcopter
View Patent ↗A modular quadcopter is provided for vertical flight. The quadcopter includes a housing, a quadrilateral set of extensions, and a quadrilateral set of arms. The housing contains flight control and sensor equipment, and has a relative vertical orientation. The housing is configurable for either stowage or deployment. The extensions are disposed on each corner of the housing. Each extension has a hinge that pitches outward and upward. Each arm is disposed on the hinge and contains an electric motor and a speed controller. The configurable below the housing for the stowage and extends radially from respective the extension in relation to the orientation for the deployment.
1. A modular quadcopter for vertical flight, said quadcopter comprising:
a housing for containing flight control and sensor equipment, said housing having a relative vertical axis with a top and a bottom and a lateral plane orthogonal to said axis;
a quadrilateral set of extensions disposed on each corner of said housing, each extension having a hinge that includes a swing joint that pivots along said lateral plane, and a pitch joint that rotates radially outward and vertically upward; and
a quadrilateral set of arms, each arm disposed on said corresponding extension and containing an electric motor, wherein
each said arm includes a proximal segment that connects to said hinge of said corresponding extension, and a distal segment attaching to an elbow that attaches to said proximal segment,
said proximal segment pivots on said swing joint into one of radially projecting beyond said corresponding extension as deployment and laterally folding alongside said housing as stowage,
said elbow pitches said distal segment radially outward and vertically downward in relation to said orientation from said proximal segment for said deployment,
said elbow pitches said distal segment vertically upward and radially inward to fold against said proximal segment for said stowage, and
said distal segment contains said motor, and said proximal segment includes a receptacle to receive said motor for said stowage.
2. The quadcopter according to claim 1 , further comprising a quadrilateral set of legs, each leg attaching to said housing against respective said extension and corresponding said arm for said stowage and underneath said hinge for said deployment.
3. The quadcopter according to claim 1 , wherein said housing further includes an antenna extending from said top for receiving a signal.
