RoboCat Drone: Robust Flying Project

The robustness of a quadcopter frame is of paramount importance in ensuring its durability and reliable performance. A well-designed and sturdy frame is built to withstand the rigors of flight, including impacts, vibrations, and other external forces. It is typically constructed from high-quality materials such as carbon fiber or aluminum, which provide excellent strength-to-weight ratios. The frame’s design incorporates reinforcement at critical stress points, such as motor mounts and landing gear attachments, to distribute forces evenly and prevent structural failure.

RoboCat is a frame that was developped with durability in mind. Structural simulations as well as real world experiances from previous failures were used during the develpment of this frame.

A robust quadcopter frame inspires confidence in pilots, enabling them to navigate challenging environments, perform aerobatic maneuvers, and carry heavier payloads without compromising stability or safety.

This frame is tested in the feild with following configurations,

• Holybro Pixhawk Mini Flight controller with PX4 flight stack
• Racerstar Racing Edition 4108 BR4108 600KV 4-6S Brushless Motor
• Racerstar REV35 35A BLheli_S 3-6S 4 In 1 ESC (Anniversary Special Edition)
• 1245 Carbon Nylon Propellers
• 4S 2200mah 60C LiPo battery

This setup was able to perform well with following abilities,

• 2.5Kg Lifting without compromising stability
• Severe crashes and still able to fly without issues (with same propellers)
• Extream flight characteristic
• Pit stop repairability

Designed and simulated with Solidworks. All CAD files related to the design can be found from the following repository.
