Solution Approach 1:

The patent replaces the mechanical wire-based power transmission system with an electromagnetic induction system. The rail contains conductive paths that generate electromagnetic fields, which inductively couple with corresponding coils in the robotic unit to transmit power and commands wirelessly, eliminating the need for physical wire connections and thereby improving flexibility while maintaining reliability through electromagnetic coupling.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

Solution Approach 1:

The rail structure serves multiple functions: it provides mechanical guidance for the robotic unit's movement along the track, contains conductive paths for electromagnetic power transmission, and acts as a structural support framework. This multi-functionality reduces overall system complexity by combining guidance and power transmission into a single integrated infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the mechanical guidance function and the electromagnetic power transmission function into the same rail structure. The conductive paths are integrated within the rail itself, so that the same physical infrastructure that guides the robotic unit's movement also provides the electromagnetic field for wireless power and command transmission, simplifying the overall system architecture.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A wirelessly powered and controlled robotic apparatus enabling performance of tasks within a three-dimensional space includes a rail, a robotic unit, and a tool. The rail comprises negative and second paths to carry an electrical current. The robotic unit comprises a microcontroller having a drive motor and a transceiver engaged thereto and is engaged to and electrically coupled to the rail. A transfer unit is engaged to both the drive motor and the rail and thus can translate rotation of the drive motor to a force to motivate the robotic unit along the rail. The microcontroller selectively actuates the transfer unit to move the robotic unit along the rail to a location. The transceiver receives commands wirelessly from a control unit and transmits data thereto. The tool is engaged to the robotic unit and can perform a task at, or proximate to, the location.
