Design and Fabrication of RF-Controlled Pick and Place Robotic Vehicle

Robotic arm is an important subset of a robot and it is defined as an electromechanical machine controlled by electronic or computer programming. They find use in tasks that are extremely hazardous or impossible for humans such as drilling, spraying, lifting heavy objects, welding, and rescue mission among others. This paper presents an RF-controlled pick and place robotic vehicle design and fabrication methodology. The components in the fabrication are: RF transceiver modules, encoder and decoder ICs, microcontroller, voltage regulator, servo motors, motor driver, battery and other electronic components and materials. The outcome is a prototype with a weight of about 1.35kg, having a dimension of 25.5cm, 20.5cm, 45.0cm, as length, breath and height respectively. The vehicle can be controlled at a maximum distance of 100m by the RF remote and perform the desired operation (pick and place of small objects) smoothly.
