| dc.description.abstract | This digital robot was designed for mopping, mowing and surveillance, it was built with common technology using the raspberry pi microcomputer, a PIC 16F877A micro-controller, ultrasonic sensors, camera, and some more components. This machine was designed to carry out tasks autonomously with little human assistance and in remote control mode. In autonomous mode the machine uses its sensors to detect objects on its path and avoid them without any physical contact. The robot could carryout survey in an environment using its surveillance features which include, camera and relay of video footage over the internet to a control base. This robot was designed to carry out tasks which are life threatening or tedious for humans to do. The machine could mow grasses to about two centimetres in height, mop floors and survey an environment. For the robot to function, the drive mechanisms involving the wheels and it’s actuators were developed using electric direct current motors and rubber tires, a radio communication channel was also developed. Remote control used in the robot is the HT12 series encoder and decoder, and also Virtual Networking using WIFI to provide internet access for control over the internet, sensors for autonomous navigation were integrated. Power system and some other electronic systems for the robot were also integrated. The power system provided power for approximately one hour thirty minutes without sunlight and between two to three hours of functionality under sunlight thereby optimising power usage. The surveillance system and the wireless internet connectivity enabled remote control over a long distance. The mopping section was developed with a Plastic container and pipped with polyvinyl materials and a drying mop. Using its sensors, the machine was able to navigate its way through a well defined environment without problems and operating effectively with little human assistance. Proper functionality of the system was eventually validated. The machine was completely built and can be further developed by improving its program and adding more sensors. | |
