To better investigate the complex collective behaviors in distributed collaborative robots, a multi-robot dynamic visualization research platform based on three-wheeled omnidirectional mobile robot is designed. The purpose of the platform is to provide an intuitive and flexible experimental environment for promoting the testing and development of multi-robot algorithms. The platform was composed of self-developed, low-cost, small, omnidirectional wheeled mobile robots and visual multi-touch screens that supported gesture recognition and shape detection of objects placed on them, enabling the configuration of various dynamic rendering scenarios. With this platform, researchers are able to focus on the design and optimization of algorithms in multi-robot systems without being limited to specific scenarios or task settings. The robot's motion performance was tested, and multi-robot algorithms were successfully tested in multiple task scenarios, initially validating the platform's effectiveness and flexibility.
