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.
