Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robotic systems for remotely controlling robots with multiple joints, such as humanoid robots, can only perform pre-programmed motions and lack real-time user input, restricting their versatility and appeal in applications like entertainment.
Innovation Solution
A robotic system comprising a transmitter with switch and analog operation sections, control signal output and transmission means, and a robot with motors and control mechanisms that allow for complex motion control by combining signals from both types of operation sections, enabling real-time attitude control and barycenter position shifting.

Engineering Contradiction Analysis
1Ease of operation
If pre-programmed motions are used for each operation section, then the robot can perform complicated motions through simple manipulation, but the robot's motion versatility is restricted and cannot reflect user's will in real time
Solution Approach 1:
The operation sections are segmented into two distinct types: switch operation sections for pre-programmed motions and analog operation sections for continuous motion control. This segmentation allows each type to specialize in its strength while the system as a whole achieves both ease of operation and motion versatility. The transmitter includes both switch operation sections (buttons) and analog operation sections (joysticks), enabling independent use of either mode depending on the desired outcome.
Solution Approach 2:
The system dynamically switches between discrete pre-programmed motions and continuous analog-controlled motions. The control signal output means processes both types of operations and combines them appropriately, allowing the robot to transition smoothly between different motion control modes. This dynamic approach enables the robot to perform both simple pre-programmed actions and complex real-time maneuvers.
2Device complexity
If only pre-programmed motions and automatic attitude control are implemented, then the control system remains simple, but the robot cannot perform various motions with real-time user input
Solution Approach 1:
The control signal output means merges signals from both switch operation sections and analog operation sections into a unified control command for the robot. This merging function allows the system to process multiple types of user inputs simultaneously and combine them into coordinated motor commands, achieving real-time motion control without requiring separate independent control systems.
Solution Approach 2:
The transmitter is designed with multi-functional operation sections that can handle both discrete switching operations and continuous analog operations. The control means on the robot side is similarly designed to accept and process both types of commands through a universal interface, eliminating the need for separate specialized control systems while maintaining full functionality.

AI summary
A robotic system is provided that enables easy manipulation and various operations. A walking operation allocated to a manipulated switch operation section is performed. Meanwhile, the right ankle roll axis control motor, the left ankle roll axis control motor, right hip joint roll axis control motor, and the left hip joint roll axis control motor are driven according to the operation amount of a manipulated analog operation section. Thus, the barycentric position of the robot is shifted to change the traveling direction of walking.
