Humanoid Robot Expo 2026 Exhibition ― Demonstrating Precision Bolt Picking with Independently Driven Hands ―

GA Robotics Co., Ltd. will exhibit at "Humanoid Robot Expo 2026" (Booth No.: 21-29) held at Tokyo Big Sight from Wednesday, April 15 to Friday, April 17, 2026, and will conduct a live demonstration of UBTECH's humanoid robot "Walker Tienkung."

■ Demo Overview: Bolt Picking by Direct Teaching

This demonstration will be executed using motion trajectories generated by direct teaching. Based on pre-set trajectories, the following sequence will be reproduced:

• Approach to the bolt

• Pinch gripping

• Stable holding

• Lifting motion

Instead of autonomous correction using visual recognition, stable gripping is achieved through precisely taught trajectories and the reproducibility of finger control.

■ Technical Features of Independently Driven Hands

Walker Tienkung is equipped with multi-degree-of-freedom hands where each finger can be driven and controlled independently.

Technical Points

• Independent actuation per finger

• Contact point control during pinch operations

• Optimized force distribution per finger

• Highly reproducible motion sequence execution

Small diameter parts like bolts present difficulties such as:

• Small gripping tolerance

• Limited contact area

• Sensitivity to posture deviation

This robot demonstrates the dexterity to reliably pick up small parts through precise control at the finger level.

■ Dual Arm Maximum Payload Capacity of 14kg

Walker Tienkung has a maximum payload capacity of 14kg for both arms combined.

While this exhibition will feature small parts, the upper limbs are equipped with sufficient joint torque, reflecting a design philosophy not limited to light work.

■ Height 172cm - Adaptability to Existing Processes

Walker Tienkung's height is 172cm. Designed to be on par with human scale, it allows for:

• Adaptation to existing workbenches

• Reuse of human-specific jigs

• Minimization of changes to workflow design

This design aims to reduce the burden of facility modifications when introducing humanoids, envisioning phased implementation.

■ Event Outline

• Exhibition Name: Humanoid Robot Expo 2026

• Dates: Wednesday, April 15 - Friday, April 17, 2026

• Venue: Tokyo Big Sight

• Booth Number: 21-29

Walker Tienkung

Walker Tienkung is a humanoid robot equipped with advanced bipedal control technology and precise hand manipulation capabilities. In this demonstration, we will showcase delicate picking tasks similar to human fingertip movements, achieved through physical AI technology integrating object recognition, motion planning, and force control, introducing its potential for practical application in manufacturing, logistics, and other fields.
