Week 8 – Final Demo

WEEK8-Final Demo
 
 The focus here was ensuring that all components worked together and recording the final video demos and live demo for the project submission.  We can say with confidence that this project is the future of entertainment, and it was a rewarding experience working on it.  Thanks for following us here on the MIST blog.
Our final report is located here:

Week 7 – Integration/Testing

WEEK7-Integration/Testing
During the final weeks we focused on integrating with the other xLab projects through the orchestration tool and set top box interface.  This essentially replaced our 2nd interface with a user customizable experience based on pre-programmed sensations provided to the orchestration tool and then time stamped by the orchestration tool and saved to the cloud.  This allows us to easily alter the experience that we previously had pre-defined.

Week 6 – UI

WEEK6-UI
We created 2 user interfaces to control the vest and sleeves.  The first interface is a test bed to try out different sensations.  When you click on an actuator on the left hand side, there is a control signal sent to the microcontroller and the response from the microcontroller appears on the right side.
The second interface shows a video on the left hand side and the interface of the vest on the right that displays the commands being sent to the vest.

Week 5 – Fluid Control Board

WEEK5-Fluid Control Board
The control board is like the heart of the entire air channel system, pumping air continuously as per the given signal.
The major components include:
1) Air Valves: to controll the air flowing in the channels.
2) Test Micro-controller : to provide the PWM for the valves to actuate.
3) MOSFET : acted as switches for the valves, a direct continuous supply of 24 volts to the air valve would have spoilt it.
4) Power regulator: to regulate the incoming voltage into 2 volts 24V for the solenoid valve and the second 5V for the the microcontroller.
5) Air compressor: to provide with the air.

Weeks 3 and 4 – The Vest

WEEK3 & WEEK4- The Vest
The main task was to begin. Keeping in mind all the ideas of the different kind of actuation we had, we begin finalizing our actuators. The finalized ones were:
1) Vibrators
2) Solenoids
3) Air channels
4) Soft Robotics
The Vest:
 As soon as we got the vest we began the work.
The biggest problem we faced at this point of time was how to arrange all the actuators. Though we had the idea of how we wanted the actuation, we were unsure as to how they would line up on the vest.
After a lot of brainstorming we fixed on the actuator positions.

Week 2 – Prototyping

WEEK2-Prototyping
It was time to start working on the proof of concept. Our basic aim was to define a micro-controller which would not only actuate all the actuators but also process the incoming signals.
To demonstrate this we developed a pair of sleeves which had vibrators lined up inside. To use the sleeves we used the particle io micro-controller called the Particle Photon.

We were in this process introduced to the biggest advantage of the photon….namely…its simplicity!!!
The photon has a cloud to which the code is pushed over the wifi, which in turn communicates to the photon.
The sleeves were a great success, we were able to control the vibrators as per our wish through the photon.

 

Week 1 – The Beginning…

WEEK1- The Beginning…

Our aim was to build a vest which actuates upon an input signal…. We had many things in mind and decided to start small. We began with some sketches as to how we can use use different actuations to our advantage.

Some of the sensation we though were hugging, massage, shooting, creepiness…

With this we now had a direction to go ahead in. Another important task for this week was to start playing with soft robotics, to understand how we could use it as an actuator in our project.
We did a lot of research and made few molds using a 3d printer to which we could pour the silicon and make some small scale soft robotics.
