Bionic Arm Prototype for People with Hand Disability
AXION Engineering Solutions has developed a bionic arm prototype for people with hand disability, focusing on assistive technology, local innovation, and practical rehabilitation support. This project shows how engineering, robotics, 3D printing, electronics, and control systems can be combined to create a functional prototype for people who need hand movement assistance or prosthetic support.
In Bangladesh, many people with limb disability or hand movement limitations face difficulty accessing affordable, customized, and locally serviceable prosthetic devices. Imported bionic arms or advanced prosthetic systems are often expensive and difficult to maintain. AXION ES is working to develop practical, low-cost, and customizable assistive technology solutions that can be improved through field testing, medical collaboration, and user feedback.
Project Overview
The bionic arm prototype is designed as a motorized assistive hand platform. It uses a 3D printed hand structure with movable fingers, internal actuation mechanism, control electronics, and future upgrade options for sensor-based or muscle-signal-based control.
The system can be developed further for:
- People with hand disability
- Rehabilitation training
- Prosthetic research
- NGO-supported assistive device programs
- Medical engineering research
- University robotics and biomedical projects
- Custom assistive technology development
The current prototype demonstrates the basic concept of finger movement and mechanical hand control. With further development, the system can be improved for real-life gripping, customized finger movement, lightweight design, wearable fitting, and user-specific operation.
Problem
Many people with hand disability depend on others for daily tasks. Simple activities such as holding objects, gripping tools, carrying lightweight items, or performing basic hand movement can become difficult.
Common challenges include:
- High cost of imported prosthetic hands
- Limited availability of customized bionic arms
- Lack of local repair support
- Difficulty finding suitable prosthetic fitting
- Heavy and uncomfortable designs
- Limited access for low-income users
- Lack of locally developed assistive technology
- Need for NGO and CSR-supported low-cost solutions
- Limited research-to-field implementation in prosthetic devices
A locally developed bionic arm can reduce cost, improve customization, and make repair and modification easier.
