Problem
Big flat screens are mounted flat against most walls. Mounts exist that allow manually pulling away from the wall and tilting at different angles. The goal is to add motion so that the TV senses the human presence and moves like this Festo wall (video). The goal is to have it ready for a new building opening celebration.

Conceive

 * Add sensor to top of TV that controls linear actuators that physically move the TV in a way that a person walking by, thinks the TV is watching them.
 * Here is the link to an example of actuator used: *6in, 250 lb linear actuator. The link to the webpage also contains the cost that the actuator required.
 * Here is the final wall, mounted by Dorion

Design
Purchased this TV Mount (video). These video describes the alternatives.

 * video
 * simulation of | the actuator working. The TV moves according to the actuator's movements.

Developed software to control linear actuators and human sensor using arduino, motor shield and two motors to practice with before ordering linear actuators.


 * Used arduino, motor shield, and to DC two motors to develop and test the software to run the linear actuators.

A demo of the TV mount's fluent movement.

Implement
This section requires to mount all the material, and have a finite product that later on could Operate. Since we did not have all the materials needed on time and some of them should be purchased by Howard Community College, we did lots of work that enable the next team to finalize the project. However, all the videos and simulations included on this page are helpful to push the project forward.
 * This link toward GitHub page. refers to all the programming that was implemented.

Operate
This section means that the product is in use and the team keeps on working to improve the design. Once again it will be a great opportunity for the next team to finalize the project and operate.

Next Steps

 * Fix CAD drawing of pin joint design
 * hook up linear actuators
 * take TV off the wall and mount
 * decide on human sensing system
