SOHO security with mini self-balancing robots

Purpose - To present the design and control of a low cost, two-wheeled, self-balancing robot for detecting and reporting fire and intruders in a small home/office setting. Design/methodology/approach - Implement an intelligent control system to make up for instabilities of low-cost components. Findings - Biologically inspired suppression system can effectively eliminate undesired sensor noises. Research limitations/implications - Improving self-balancing robots' tolerant to impulsive forces from the sides allows them to be designed with smaller front-prints. Practical implications - Inherited high maneuverability together with miniature design enables self-balancing robots to navigate smoothly through tight space. Originality/value - Demonstrates the control of a dynamically unstable system can be controlled using a simple suppression mechanism.
