Automatic Wheel Chair Cum Bed – Mechanical Project
Introduction:
轮椅已成为大多数运动障碍者的福音，从较早的介绍开始。随着时间的变化，轮椅的需求也改变了，以找出不同类别的患者的需求。这一领域的许多研究都在进行，旨在满足这些要求。床训练的患者有时会感到孤独，并渴望改变氛围。他们使用了普通的轮椅，但该轮椅是通过手动手段移动的。这是自动轮椅暨床的重要性，因为这不需要看护人。机器人技术，人工智能和传感器技术的最新发展有望在高级轮椅的发展方面范围巨大。为了克服问题，需要设计具有足够功能的自动轮椅暨床。自动轮椅暨床由轮椅组成，可以将其转换为完整的床。自动轮椅暨床可以通过操纵杆，遥控器等控制。
电动轮椅或电动轮椅是轮椅，它是通过电动机而不是手动电源推动的。机动的轮子椅对于那些无法施加手动轮椅或可能需要在手动轮椅上使用轮椅或在地形上的车轮椅子的人很有用。它们也可能不仅是由常规流动性障碍的人使用，而且还可以由患有心血管和疲劳状况的人使用。电动轮椅通过负担得起的动力主持人的流动性增强了许多身体残障人士的生活质量，这将依赖许多因素。包括将椅子设置的那种表面设置将被驱动，需要解决阈值和路缘，以及在习惯环境中的间隙宽度。椅子的最基本工作是从用户那里获得输入，通常是以小型操纵杆的形式获得，并朝着首选的方向移动人。在过去的几年中，人们看到了丰富的改进和模型，可以从用户努力和车辆能力方面对用户无与伦比的控制。
Problem Formulation:
- Difficulty in transferring patient to bed from wheel chair.
- Uncomfortness felt by the patients when sitting for a long time.
- 截瘫患者。
Objective:
- The objective of this project is to analyze and prototype an automated wheel chair cum bed, based on an existing smart wheel chair with extensive fact findings and research on existing models, technology used, market scenario and customer requirements.
- It improves the balance and postural stability of old age people. It can convert sleeping position from sitting position easily.
Methodology:
- The course of our work begins with the planning phase involving initial research, literature survey and background study.
- 其次是概念生成阶段，其中包括评估现有轮椅，客户需求和概念设计。
- Prototyping the wheelchair into complete bed using pneumatic system by means of 2-5 bar pressure and we progress towards testing a feasible model.
- Collection of all the equipment’s and materials required for overall wheel chair cum bed enhancement setup.
- Forming of a light weight wheel chair cum bed structure which would carry up to 80-90 kg.
- Successfully coding of a specific program, which would run the device directionally by using joystick, head motion.
- Implementation and connection of all the equipments like motors, micro-controller, joystick, accelerometer and other sensors together.
- Implementation of pneumatic cylinders, which would converts the Wheel chair into Bed and lifts the wheel chair into adjustable height.
Scope for improvement:
Automatic wheel chair cum bed has a wide range of scope in following areas:
- 身体残障人士可以根据自己的目的使用它。能够使用手的人可以使用操纵杆。
- People suffering from certain paralysis can use either head movement or Bluetooth module as per requirement.
- Patients in the Hospitals
- People at old age homes can use this chair as per their requirement
- 专注于卧铺人的流动援助
进一步的增强：
- We can attach a mini compressor in the wheel chair itself that leads to easy movement and comfortness of the height and bed adjustment of the wheel chair.
- 太阳能电池板屋顶可用作替代电源，也可以是雨水和阳光的保护层。
- By this system wheelchair will move to the destination given by the patient by using GPS technology. This technology is currently used in driverless cars in various countries.
- 通过使用合适的传感器，我们可以预测附近的物体，这使轮椅的移动易于移动。
