• Final testing of 2nd prototype

    After we had painted the modules individually, we joined them along with the emg circuit to detect muscle twitching. We also combined the complete pneumatic system for testing it.

    The 2nd prototype being tested by 1 of our members.

  • Working with EMG (Electromyography)

    We designed an amplifier and filter circuit for EMG. EMG is electromyography. We used EMG to detect the twitching of muscles so that the exoskeleton's pneumatic pistons can be controlled on the basis of which joint the user wants to move.

  • Making and painting the 2nd prototype

    Rohit Bhaskar • 10/01/2016 at 19:13 • 0 comments

    We improved upon the previous prototype and came up with our version 2. The upgrades included proper joint coupling, a newer frame, painting, padding for more comfort.

    This prototype also has a bag behind to house the pneumatic valves and bottles for storing. The prototype is now ready for testing

  • 1st prototype testing

    1st prototype testing. The initial prototype was made using basic materials and was tested directly with the air compressor connected. The prototyped worked and gave proof that many imprvements were possible

    The 1st prototype consists of a hard coded motion of legs. Yet to test the EMG probes.
