Compass C2 four-wheel differential platform
Product Briefing
The Compass series is a small fundamental robot platform. It aims to provide users with a complete mobile robot system with high reliability and multiple interfaces. Compass C2 is a robot platform equipped with HSL-15 inflatable rubber driving wheels and a powerful drive system, which can adapt to all kinds of working environment and complete all kinds of sports efficiently. The chassis of this platform adopts overall aluminum casting & molding process. Compass C2 uses four high-power coreless motors as the driver, equipped with multi-axis servo driver, supporting both CAN bus and RS232 interface. The development kit provides customers with a complete equipment communication protocol, and also provides examples and demo application source code based on STM32F407, which allows users quickly know how to operate Compass C2
