The storage size is as compact as your palm.
It smoothly extends only when needed, supporting inspections and photography at height.
Ladders, drones… high-altitude work takes time and comes with risks. There must be a better way.
Inspections and photography at height require ladders and heavy equipment, raising concerns about fall risks and costs. The BambooShoot Actuator takes care of all that hassle and worry.
Using a tape-measure-style mechanism, it delivers a lightweight, simple, and high-performance solution.
A smart robotic component that extends instantly, only when you need it.
This device folds into a compact box approximately 20 cm in size. With a single switch, it extends smoothly up to 4 meters, allowing operators to reach equipment and switches located at elevated positions.
Compact Storage & Lightweight

Stored in a palm-sized case and weighing only about 3 kg, it’s lightweight and easy to handle.
Extends up to 4 meters.

A single unit supports multiple functions
The actuator section can accommodate a variety of devices, enabling a single unit to perform multiple inspection tasks such as 360° imaging and fire alarm testing.
Use Cases
- Robotic arm use:Used to press building intercom buttons.
- An “Extendable / Retractable eye” for robots:Enables flexible vertical adjustment of a camera mounted on autonomous mobile robots and similar platforms.
- Facility inspections:Supports routine inspections of HVAC systems and fire alarms, contributing to manpower reduction.
- Drone alternative:Enables high-altitude imaging and measurement from the ground in environments where drones cannot be deployed.
- Office environment monitoring:Measures HVAC parameters (airflow speed and volume), illuminance, and other data in three dimensions across multiple points within an office.
