Development of stair climbing robot for goods transport

This paper discusses about to develop a stair climbing robot for goods transport and to deliver the goods that the robot carries. For the stability of the robot, here we use rocker boogie mechanism. This mechanism makes more efficient in carrying load, reduce friction on ground or climbing and cannot get the reverse movement, due to gravitational force. This paper shows the working of rocker-bogie suspension framework in order to ensure high mobile steadiness as well as excellent versatility of a prototype made with six-wheeled mechanism. The use of PVC pipes as the frame of our robot. And ultrasonic sensors were used to detect the obstacles that robot faces during on process working. This robot works specially on delivering the goods without human intervention. This robot can be useful in various applications like food delivery, grocery delivery, and posts delivery in apartments. The rover’s design was completed using the SOLIDWORKS and prototype testing was done. The project’s outcomes include the implementation of independent directional control using minimal drive modules, which boosts battery performance and extends the rover’s operating time, nearly zero tilt of the main body of the rover through self-balancing of the body counterweight method, which boosts stability and decreases the rover’s tilt or overturning percentage, and finally direct linkage of the various links that make up the rover. Therefore, the different enhancements guarantee structural integrity, tilt stability, mechanical integrity, overall weight reduction, and mechanical viability.
