Abstract

The invention discloses a micro flapping wing robot with independent power supply, which comprises a fuselage support frame, a wing, a piezoelectric driver, a high-voltage pulse power supply module, awireless communication module and a transmission amplification mechanism. The micro flapping wing robot comprises an airframe support frame, a wing, a piezoelectric driver, a high-voltage pulse powersupply module, a wireless communication module and a transmission amplification mechanism. Piezoelectric ceramic bimorph is used as piezoelectric actuator, piezoelectric ceramic bimorph drives wing through drive amplification mechanism. The high voltage pulse module outputs a high voltage pulse square wave signal. The wireless communication module receives the control signal from the ground and controls the output of the high voltage pulse module. In flight, piezoelectric ceramic bimorph acts as piezoelectric actuator, inputs high voltage pulse signal, amplifies and converts the vibration ofpiezoelectric ceramic bimorph into wing vibration frequency and duty cycle through transmission amplification mechanism, and then controls the amplitude and angle of flutter of two wings, realizes forward, backward, steering, hovering and other flight postures. The robot can fly autonomously for a long distance because of its power supply system. Flight control of robot is realized by wireless communication, and the robot has strong adaptability to bad weather.

Description

Technical field [0001] The invention relates to an autonomously powered miniature flapping-wing robot, which belongs to the technical field of robots. Background technique [0002] The flapping-wing flying robot is a flapping-wing flight mode that simulates flying creatures. It can play a huge role in the military and civilian fields. It is a hot research topic in recent years. Compared with the fixed-wing and rotor-wing flying methods, the flapping-wing flying method can adapt to severe weather such as strong wind and heavy rain, and has a smaller size and lower energy consumption. [0003] Energy and power issues are the primary problems faced by micro-aircraft. Using a micro motor as a power source has disadvantages such as complex structure and low efficiency. Piezoelectric ceramics are a kind of functional ceramic materials that can convert mechanical energy and electrical energy. It opens up a new way for the dynamic driving of flapping-wing robots. At this stage, miniatur...
