Robo-Magellan
Electrical
The electrical subsystems of this robot are being compiled in a modular fashion, in anticipation of easily migrating individual modules to future endeavors. The primary medium over which all of these modules will communicate is that of the I2C (Inter-IC) bus. Supporting over 120 unique devices per simple 2-wire bus, and data transfer rates of up to 100kbits/s (400kbits/s in high-speed mode), the I2C bus more than meets our needs.
Thus far, we've identified the following individual electrical systems that need development. Each system is a separate project, with somewhat independent development timelines and resources. All information relevant to a specific project is available on the project's page:
- Main Computer - a Mini-ITX form factor PC motherboard provides the primary platform for development of higher level intelligence.
- Interface Controller - this dedicated microcontroller serves as the interface between the main computer and the rest of the robot's systems.
- Power Supply - this includes the main system batteries, and electronics for monitoring and regulating power to all other system components.
- Motor Controller - a robust 10 channel motor controller is required for properly actuating all of the motors present on our current mechanical design.
- Sensors
