A novel robotic solution has been developed to aid wheelchair users in interacting with hard-to-reach buttons, such as those for opening doors or calling elevators. Modeled after the collapsible and expandable design of a fireman's ladder, this robot can extend to various heights, offering a versatile and practical tool for individuals with mobility challenges.

​

The core mechanism of this robot is inspired by the functionality of a fireman's ladder, allowing it to collapse into a compact form for easy storage and transportation, and then expand as needed to reach buttons at different heights. This adaptability ensures that users can access controls in a wide range of environments, from public buildings to residential settings, enhancing their independence and ease of movement.

​

Controlled by an Arduino microcontroller and driven by stepper motors, the robot's movements are precise and smooth, ensuring that the extension and retraction of the ladder mechanism are both reliable and efficient. The Arduino platform provides a flexible and user-friendly basis for the robot's operation, allowing for easy customization and adjustment of its functions to cater to the specific needs of individual users.

​

The device is designed to be mounted on a wheelchair, integrating seamlessly with the user's daily life. Its operation is straightforward, with intuitive controls that can be activated by simple switches or other adaptive input devices tailored to the user's preferences. This ensures that the robot is not only functional but also accessible to users with varying levels of physical ability.

​

Safety and durability are paramount in the design of this robotic ladder. It is constructed from lightweight yet sturdy materials that can withstand the demands of daily use, and incorporates safety features to prevent overextension or accidental collapse while in use. Additionally, the use of stepper motors allows for precise control of the ladder's movement, minimizing the risk of unintended interactions with the environment.

​

This innovative robotic ladder represents a significant advancement in assistive technology, providing wheelchair users with a new level of autonomy in interacting with their surroundings. By enabling easy access to buttons and controls that were previously out of reach, it opens up new possibilities for independence and engagement in community life. The combination of collapsible design, precise control, and user-friendly operation makes this robot an invaluable tool for enhancing the mobility and quality of life of individuals with mobility challenges.
