What tasks is Walker Tienkung good at?

Walker Tienkung excels at precision picking of small parts like bolts using its independently driven hands, and can carry objects weighing up to 14 kg with its dual arms.

Is it easy to introduce into existing factories?

With a height of 172 cm, equivalent to a human scale, it can utilize existing workbenches and jigs, reducing the burden of facility modifications.

Where can the demonstration be seen?

It will be demonstrated at the 'Humanoid Robot Expo 2026' held at Tokyo Big Sight from April 15 to 17, 2026.

GA Robotics will exhibit at "Humanoid Robot Expo 2026" and demonstrate UBTECH's humanoid robot "Walker Tienkung." Key features include precision bolt picking with independently driven hands, a maximum payload capacity of 14kg with dual arms, and a human-scale design.

GA Robotics Co., Ltd. will exhibit at the "Humanoid Robot Expo 2026" (Booth No.: 21-29) to be held at Tokyo Big Sight from April 15 (Wednesday) to 17 (Friday), 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, a series of sequences 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 independently driven and controlled.

### Technical Points

- Independent actuation per finger - Contact point control during pinch operations - Optimized force distribution for each 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 machine 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 total maximum payload capacity of 14kg with dual arms.

Although this exhibition deals with small parts, the upper limbs are equipped with sufficient joint torque, designed not to be limited to light work.

■ Height 172cm ― Adaptation to Existing Processes Walker Tienkung's height is 172cm. Because it is designed on a human scale, it allows for:

- Adaptation to existing workbenches - Diversion of human-use jigs - Minimization of changes to movement lines

It is designed with a view to gradual implementation, reducing the burden of facility renovation when introducing humanoids.
