Designing Robotic Lifting Systems: Calculating Power Needs for Wall-Mounted Robots and Quad-Rotors

Abstract

Robotic systems are becoming increasingly sophisticated, with diverse applications that often demand precise calculations to achieve optimal functionality. This study focuses on designing and calculating the power requirements for two common robotic lifting scenarios: wall-mounted robots and quad-rotor drones. For wall-mounted robots, which typically rely on dual motor systems to lift and support loads vertically, we provide a detailed analysis of motor power calculations necessary to handle payloads of 300 grams and above. By incorporating various factors such as torque, gravitational force, and motor efficiency, we propose formulas and present tables that guide motor selection to ensure adequate lift. In the case of quad-rotor drones, thrust calculations become crucial as these systems require balanced power distribution across four rotors to lift payloads of 400 grams and potentially heavier loads. This article explores different approaches for calculating thrust, examining variables such as rotor speed, blade size, and air density to optimize lift capability. Through comparative analysis, we suggest methods for improving payload capacity and energy efficiency in each system. The findings offer practical insights for engineers and researchers working on robotics applications that demand precision in motor selection and thrust optimization. This article ultimately aims to contribute to the field by providing a foundation for designing efficient and reliable robotic lifting systems.
