Exercise Coaching Robot Control Through User Tracking and Gestures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods fail to provide strong motivation for users to exercise, as simply presenting nudges through messages or temperature-based considerations is insufficient to change exercise habits effectively.
Innovation Solution
A control method for a robot that receives exercise encouragement instructions, detects user position, moves into the user's area, performs gestures to encourage exercise, and adjusts its actions based on user behavior monitoring, thereby providing stronger motivation through active engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If passive message-based approaches are used to encourage exercise, then the system complexity is low, but the motivation effectiveness is insufficient
Solution Approach 1:
The robot serves as an intermediary between the exercise encouragement system and the user. Instead of directly delivering messages through simple notifications, the robot physically approaches the user, performs gestures, and provides companionship during exercise, thereby significantly enhancing motivation effectiveness while maintaining manageable system complexity through modular design
Solution Approach 2:
The patent replaces passive electronic message delivery with active mechanical interaction. The robot uses its physical body to approach the user, perform encouraging gestures with arms and legs, and provide tactile companionship during exercise, transforming abstract digital encouragement into concrete physical engagement that significantly boosts motivation
2Reliability
If the robot actively engages with the user through movement and gestures, then the motivation effectiveness increases, but the energy consumption increases
Solution Approach 1:
The robot employs periodic action by alternating between active engagement phases (approaching user, performing gestures) and passive monitoring phases (remaining stationary, observing exercise progress). This rhythmic pattern of activity allows the robot to maintain high motivation effectiveness while managing energy consumption through strategic rest periods
Solution Approach 2:
The robot dynamically adjusts its energy expenditure based on real-time exercise conditions. It intensifies physical engagement when user motivation appears to wane (detected through monitoring) and reduces activity when the user is performing well, optimizing the balance between motivation effectiveness and energy consumption throughout the exercise session
3Reliability
If the robot monitors user behavior continuously, then the exercise adherence improves, but the device complexity increases
Solution Approach 1:
The robot implements continuous behavior monitoring with real-time feedback mechanisms. Sensors track user exercise parameters such as movement intensity, duration, and form, providing immediate feedback through gestures and adjustments to encouragement strategies. This closed-loop feedback system ensures high exercise adherence while managing complexity through integrated sensor-fusion algorithms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The robot effectively motivates users to exercise by actively engaging with them, increasing the likelihood of behavior change and improving exercise adherence compared to passive message-based approaches.
Implementation Method 1
detecting a current position of the user through an optical sensor included in the robot
Implementation Method 2
monitoring behavior of the user through the optical sensor or a microphone included in the robot

AI summary
A control method of a robot according to an aspect of the present disclosure includes receiving from an external computer information that instructs the robot to encourage a user to exercise; sensing a user's current position; moving the robot into a predetermined area that includes the user's current position; causing the robot to perform a gesture to encourage the user to exercise; monitoring behavior of the user; and performing driving of the robot along with exercise of the user, based on a result of the monitoring.
