This exoskeleton was designed to help a patient suffering from paralysis to rehabilitate faster.
Thank you!! will definitely look into it when I will work for the next version.
The current Arm Support Model of this exoskeleton model uses a link mechanism to raise and lower the arms, which requires the servo-motor to be mounted on the support. The link mechanism increases the torque produced by the servo-motor enabling it to lift the arm. In the present work, the complete link mechanism can be replaced with the same cable mechanism that is being implemented on the exo-glove. Instead of links, Bowdon cable mechanism can be used to raise and lower the arms. Currently, a joystick is used to operate the exo-glove. On moving the joystick, the actuation signal is sent to the Arduino which moves the servo-motor. This can be replaced by the EMG. The sensor along with the diodes can read the electric potential produced by the muscles of one hand that is functional. This data can be feed to microcontroller connected to the EMG through wires. This will enable the exo-glove to replicate the movements of the other hand, removing the need for a joystick. The current model doesn’t provide any solution for wrist movement. A simple wrist rotating mechanism can be embedded to allow the patients to move their wrist as well. This will increase the degree of freedom of their hand making them use their hand in a better way and making them feel more normal psychologically. In this case, actuation is being controlled using a joystick or maybe an EMG as an enhancement but this can be totally replaced by neuro-sensor. These sensors can enable the patient to control and actuate the exoskeleton directly from brain pulses, making it work similarly to any normal limb. The sensors will be attached to the brain of the patient and receptors will be available inside the exoskeleton. When the brain sends a signal to move the limb that the signal will be received by the neuro-sensors and transmitted to the exoskeleton. Thus, creating a movement of the non-functional limbs similar to that of a normal limb.
