Introduction
Robotics is a fascinating subject – more so, if you have to fabricate a robot yourself. The field of robotics encompasses a number of engineering disciplines such as electronics, structural, mechanical and pneumatics.
The structural part involves use of frames, beams, linkages, axles, etc. The mechanical parts/accessories comprise various types of gears (spurs, crowns, bevels, worms and differential gear systems), pulleys and belts, drive systems (differentials, castors, wheels and steering), etc. Pneumatics plays a vital role in generating specific pushing and pulling movements such as those simulating arms or leg movements. Pneumatic grippers are also used with advantage in robotics because of their simplicity and cost-effectiveness. The electrical items include DC and stepper motors, actuators, electrical grips, clutches and their control. The electronics part involves remote control, sensors (touch sensor, light sensor, collision sensor, etc), their interface circuitry and a microcontroller for overall control function.
1.1 The Project
What we present here is an elementary robot used for fork lifting that finds its way by itself. The robot is programmed with a predefined path and its movements are observed accordingly. The proposed robot can move in forward, backward, left and right directions and can be used to serve fork lifting purpose as well.
Forklift robots are frequently applied in automated logistics systems to optimize the transportation tasks and, consequently, to reduce costs. Nowadays, in a scenario of extremely fast technological development and constant search for costs minimization, the automation of logistic process is essential to improve the productivity and reduce costs. In order to decrease costs of logistics and distribution of goods, it is quite common to find in developed countries mechatronic systems performing several tasks in harbor, warehouses, storages and products distribution center.
