Solution Overview
Problem
Autonomous robot systems face challenges in power management and communication efficiency, particularly in battery-powered robots that require continuous human guidance and lack effective power-saving mechanisms and robust networking capabilities.
Innovation Solution
A power-saving robot system with a mobile robot and peripheral device that utilize wireless communication components to enable communication and activation protocols, allowing the robot to function as a fully functional network node, including hibernation modes for power conservation and customizable audio content for user interaction, along with a network data bridge for internet protocol compliance and remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the peripheral device operates in active mode continuously, then communication responsiveness is improved, but power consumption increases
Solution Approach 1:
The peripheral device alternates between active mode and hibernation mode in periodic cycles. During active mode, the device is fully operative and can communicate immediately. During hibernation mode, the device enters a low-power state with limited functionality. This periodic switching resolves the contradiction by providing responsive communication only when needed while conserving power during idle periods.
2Reliability
If the wireless communication component remains active, then communication capability is improved, but power consumption increases
Solution Approach 1:
The wireless communication component dynamically changes its operational state based on system needs. It transitions between fully active, partially active, and hibernation states. This dynamic behavior allows the system to maintain communication capability when required while minimizing power consumption during idle periods, resolving the contradiction between communication reliability and energy usage.
3Adaptability or versatility
If the robot functions as a fully functional network node with internet connectivity, then networking capability is improved, but device complexity increases
Solution Approach 1:
A network gateway or bridge device serves as an intermediary between the robot and the internet network. The robot communicates with this intermediary through wireless communication, and the intermediary handles complex networking functions including protocol conversion, routing, and internet connectivity. This approach provides full networking capability to the robot while offloading complexity to the intermediary device, resolving the contradiction between versatility and device complexity.

AI summary
A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect, a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.
