TL;DR

This paper presents a virtual reality simulation framework for designing fire-fighting robots used in student robotics competitions, enabling students to test algorithms, sensor-actuator configurations, and parameters before physical prototyping. The simulation evaluates time-to-extinguish-flame and algorithm efficacy, reducing trial-and-error development and improving design efficiency and competition readiness.

ABSTRACT

This paper presents one approach in designing a Fire Fighting Robot which has been contested annually in a robotic student competition in many countries following the rules initiated at the Trinity College. The approach makes use of computer simulation and animation in a virtual reality environment. In the simulation, the amount of time, starting from home until the flame is destroyed, can be confirmed. The efficacy of algorithms and parameter values employed can be easily evaluated. Rather than spending time building the real robot in a trial and error fashion, now students can explore more variation of algorithm, parameter and sensor-actuator configuration in the early stage of design. Besides providing additional excitement during learning process and enhancing students understanding to the engineering aspects of the design, this approach could become a useful tool to increase the chance of winning the contest.
