What are some good strategies to follow while designing power supply for electrical systems on mobile robots?
Such robots typically comprise of systems with
- microprocessor, microcontroller, DSP, etc units and boards along with immediate peripherals
- Motor control
- Analog Sensors(proximity, audio, voltage, etc)
- Digital Sensors (Vision, IMU, and other exotica)
- Radio comm circuits (Wifi, Bluetooth, Zigbee, etc)
- Other things more specific to the purpose of the robot being designed.
Are there unified approaches/architectural rules to designing power systems which can manage clean power supply to all these various units which may be distributed across boards, without issues of interference, common ground, etc? Furthermore, also including aspects of redundancy, failure management, and other such 'power management/monitoring' features?
well explained examples of some such existing power systems on robots would make for excellent answers.
