Design and Implementation of a Cost-Effective Semi-Autonomous Scissor Lift Robot for Industrial Material Handling

This paper presents the mechanism, system configuration, basic control algorithm, and integrated functions of a Semi-Autonomous Robotic Lift designed for efficient industrial material handling. The robot combines the capabilities of traditional manual tools with advanced sensors, including infrared, ultrasonic, and gesture sensors, to carry, lift, and navigate within a specified area. The use of a gesture sensor enables a user-friendly command protocol for scissor lift operations through simple hand movements. The robot's stability on uneven surfaces is ensured by four wheels and robust materials, such as steel and 3/4” wood, allowing it to withstand heavy loads safely. Safety protocols, including speed limits, light indicators, and an emergency stop button, adhere to industry standards. The Semi-Autonomous Robotic Lift, constructed with a mixture of steel and plywood, aims to facilitate the transportation of heavy materials in indoor industrial or warehouse settings, providing a cost-effective alternative to existing products.
