Background
Drones have provided significant improvements for industries including surveillance, research, and agriculture with their highly advanced aerial abilities. They provide enhanced safety and security measures and allow critical tasks to be completed remotely. Drones enable goods to be transported rapidly to remote areas with little infrastructure for traditional aircraft. Despite significant technological advancements, many drones still struggle with stability and efficiency, particularly in tasks that involve perching and grasping. As drone use continues to expand globally, there is a need for drone technology that provides greater stability and efficiency.
Invention Description
Researchers at Arizona State University have developed a whole-body grasping and perching (WHOPPEr) drone. The drone utilizes its entire body for perching and a partial body mechanism for grasping, reducing weight and enhancing grasping capabilities. During perching, the drone can operate with the motor off, saving battery life and increasing operational duration. The arms of the drone feature a bistable structure to improve stability and efficiency. While maintaining a stable altitude, WHOPPEr employs actuators to activate and reset its perching arms. Propeller thrust is used to retract the arms for strong, precise grasping.
Potential Applications:
- Navigating tough terrains during search and rescue operations
- Long term stable surveillance and monitoring
- Collecting hard-to-reach samples for research
- Assessing infrastructure remotely for inspection, repair, and maintenance
- Providing drone delivery services capable of holding heavier goods
Benefits and Advantages:
- Increased battery life
- Strong grasping abilities
- Enhanced perching stability
- Lightweight and easily maneuverable
