STYLE AI JUNIOR’s Virtual Grid Safety System (VGSS) creates a configurable 3D safety envelope around the client to ensure safe, precise, and predictable robotic hairstyling. Using layered Safe, Caution, and Critical zones, VGSS continuously manages robot speed, force, trajectory, and approach distance throughout every styling workflow.
Unlike traditional static safety systems, VGSS dynamically adapts to the client’s position, hairstyle requirements, and operational conditions. The system combines virtual spatial monitoring, force sensing, and motion verification to maintain both safety and cutting accuracy in close human-robot interaction environments.
VGSS is built around a Virtual Cylinder Grid structure that defines multiple safety regions surrounding the client.
The Safe Zone serves as the robot’s primary operating area, allowing stable movement and trajectory planning under normal operating conditions.
Key functions include:
Standard motion execution
Stable trajectory transitions
Continuous monitoring
Safe recovery positioning
As the robotic arm approaches the client, additional safety controls are activated.
Protective behaviors include:
Reduced movement speed
Increased force sensitivity
Dynamic trajectory adjustment
Enhanced safety verification
The Critical Zone applies the strictest safety limitations near the client’s head and scalp.
Within this zone:
Speed and force are heavily restricted
Real-time sensor monitoring is intensified
Abnormal readings trigger immediate retreat to the Safe Zone
To replicate professional hairstylist workflows, VGSS requires the robotic arm to complete a verification sequence before every cutting action.
The system automatically:
Returns to a Safe Grid reference point
Verifies posture and tool orientation
Recalculates a safe cutting trajectory
Confirms force, hair direction, and safety distance
Each cutting motion is then executed along a pre-validated path while continuously monitored by six-axis force sensors.
VGSS continuously evaluates motion, force, and proximity data in real time. If abnormal force, unexpected contact, or unsafe movement is detected, the robotic arm immediately stops and retracts to a safe position.
The system provides:
Dynamic motion limitation
Continuous force/torque monitoring
Automated emergency retreat
Redundant safety verification mechanisms
VGSS is designed to emulate the disciplined workflow of professional hairstylists — “confirm position, perform localized cutting, return to reference, and reassess.”
By combining adaptive safety zoning, predictive motion control, and real-time sensing, STYLE AI JUNIOR delivers a robotic styling platform focused on precision, consistency, and user safety.
