This paper introduces TeamBots as a tool for mobile robotics research. TeamBots enables researchers to develop
robotic control systems and test the control systems in simulation as well as on physical robots. Simulation plays
important roles in multi-robot research. Interaction among robots in multi-robot systems can produce interesting
phenomena. It is hard to predict the effectiveness of a control system without simulating it in a multi-robot
environment. This paper presents a case study and compares it to closely related work. The experiment result
shows that even for the same task (i.e. foraging) a control system that performs best in a particular environment
may not be the best control system in different environments.
