Background: This study is to help reader to understand Robotics by developing a robotic system which is practically useful by collecting, generating environmental quantities and analyzing it.
Methods: Chassis can be made in CAD format and wiring is tested beforehand. Constraint in Pi is limited GPIO, so we use two Pi’s for different uses. Accessing possible via wireless system, SSH, VNC or port forwarding. Calculation of speed, rotation time done. We also deduce the relation between the distance travelled and the temperature of the CPU of the Raspberry Pi. We also compare and suggest best cooling solutions.
Findings: We can construct a rover which can detect the environmental quantities like temperature, human presence, animal presence, humidity etc. with the help of two raspberry pi’s and an H-bridge, which can be accessed over the internet and the live stream can be obtained on a remote screen. The rover we construct can travel on the speed of 0.18 meter per second. It will take nearly 1.10 seconds to turn at a 90 degree rotation and double of that (2.20 seconds) for a 180 degree rotation. When we perform temperature analysis we find out that temperature almost linearly increases with the distance travelled, and the base temperature of the raspberry pi can be reduced by adding the cooling solutions like small heat sink, fan and larger heats ink. Equations are deduced using method of regression. We conclude that a bigger heats ink, enough to cover the CPU can be the best method to cool a rover which is based on raspberry pi as its single board computer.
Applications: Detection of environmental quantities to detect problem/hazard/performing disaster mitigation is the application of the rover and the paper would also help in developing cooling solutions for the rover further.
