EVAS Voice-Controlled Robotic Legs: A New Level of Interactive Movement
Aug 31,2026 | colin
EVAS is introducing a new robotic leg-movement system designed to make compatible dolls more interactive and dynamic.
Available for selected EVAS 170cm and 182cm bodies, this motorized upgrade allows the doll to perform a variety of leg movements through voice commands or button controls. From lifting an individual leg to performing a split, the system brings automated physical movement to the EVAS experience.

Six Motorized Degrees of Freedom
The robotic system uses six joint motors to control the legs:
-
Four motors located around the thighs and hips
-
Two motors controlling the knees
Together, these motors allow the legs to move independently or simultaneously. The system is designed to perform several preset movements while the doll is lying down.

Available Voice and Button Commands
The current robotic leg system supports the following commands:

1. Lift the Left Leg
The doll raises her left leg while keeping the other leg lowered.
2. Lift the Right Leg
The doll raises her right leg independently.
3. Spread the Legs
Both legs move outward into an open position.
4. Straighten the Right Leg
The right knee extends and straightens the leg.
5. Straighten the Left Leg
The left knee extends and straightens the leg.
6. Raise Both Legs into a Straddle Position
Both legs are lifted and moved apart simultaneously.
7. Perform a Full Split
The legs move outward into a full horizontal split.
8. Return to the Resting Position
Using the “That’s enough” command, the system slowly lowers both legs and returns them to the resting position.

Compatible EVAS Bodies
This robotic leg upgrade is currently available for the following EVAS body sizes:
-
EVAS 170cm body
-
EVAS 182cm body
The system is not currently available for other body sizes. Please confirm compatibility with us before placing an order.
