Title: Human Muscle Like Air Control Upper Arm Rehabilitation System

Description:  

Human race are getting more ages from the benefit of better medical attension. Yet from the other side, more injuries to muscles or bones may affect senior citezen's everyday life. In order to lower the cost of senior citizen care, we research and develope a multi-degree freedom upper arm rehabilitation.

Products: 

                                 NI myRIO、LabVIEW

                         Air compressors

                         Human mucle alike Air Control valve x 7

                         Controller x 2

                         Pressure adjust valve x 3

                         Pressure sensor x 4

                         Load cell x 2

                                 Linear acuator

The Challenge:

Rehabilitation system with stiff motion can cause patient felt uncomfortable. We implement the system with Air control mucle alike valve on each degree of freedom.  The PAM actuator, AKA, McKibben muscles can have cushion feel while undergoing rehabilitation process.


The Solution:

We wish to leverage Upper arm hebalitiation mechanism to help patient to perform excercise. We develope a 4 degree of freedom arm that control by NI myRIO. We also leverage Festo air muscle valve, encoder, servo valve,load cell and pressure sensors to locate and track the arm movement in order to achieve rehabilitation process.NI myRIO has all the I/O we need to achieve pressor sensing, encoder reading and control command to the air muscle vavle.

At early stage, we use SolidWorks to draw in 3D and use simulation to immitate the movement behavior. And later we can use NI myRIO and LabVIEW to do faster prototyping. NI solution help us alot on measure and control our Rehab Arm. And myRIO FPGA can provide use accurate and fast response need for PID position control. With graphic nature of LabVIEW, we can see the value of each degree of freedom from the robot arm while we can emphisize our time on designing better arm's trajectory and listen to patient's feedback.
