Area of Science:

• Robotics
• Biomimicry
• Mechanical Engineering

Background:

• Robotic jumping research aims to improve navigation in unstructured environments.
• Achieving precise and predictable jumps in dynamic settings remains a significant engineering challenge.
• Earth's gravity requires powerful actuators and lightweight designs for high robotic jumps.

Purpose of the Study:

• To develop a bipedal robot capable of precise, predictable, and extended-range jumps in dynamic environments.
• To overcome limitations of current robotic jumping systems in terms of range and adaptability.
• To advance the fields of engineering and biomimicry through novel robotic locomotion.

Main Methods:

• Utilized a bipedal robot employing thrust-induced hypogravity.
• Implemented dual regulation of aerial attitude and parabolic trajectory via thrust vectoring.
• Tested the robot's ability to clear obstacles like stairs, walls, and streams, and navigate dynamic scenarios.

Main Results:

• Achieved a maximum leap range of 6.9 meters, exceeding leg force limitations.
• Successfully cleared multi-level stairs, a 2.35-meter wall, and a 3-meter stream.
• Demonstrated precise leap distance control, enabling navigation through fast-moving windows and onto shifting targets.

Conclusions:

• Self-generated hypogravity and parabolic trajectory regulation significantly enhance robotic jumping capabilities.
• The developed robotic jumping system offers extended range, precision, and predictability for dynamic environments.
• This research paves the way for more adaptable and capable robots in complex, real-world scenarios.
