EXPERIMENT_15
Final Simulation
In the classroom, I simulate a final project. It is very successful simulation. But There are some problems with the final model. First The ration of water to oil was only 2:1. So I could't see movement of oil.
EXPERIMENT_14
Structure for Moblie Phone and Oil in Box
The loads need to be a little shorter. Because The stewart platform has a problem in the previous experiment. The load is too long. So its condition was unstable. I change a shorter load. So The stewart platform is more stable than previous that.
Stewart platform
And I design a structure for a camera tracking system. Above all, The mobile phone is used to tracking oil in box. Because The resolution of webcam has a problem in the previous system. And It is difficult in the focus. It has no function for changing focus.
After assembling the mobile phone and structure, I put some oil in the box. And I mix water with blue acrylic paints. The water and oil is administered by injection device. It's very useful device.

EXPERIMENT_13
Test a Mouse Turntable and Stewart Platform
At first, I experiment movement of a stewart platform which is operated by two turntable.
Total System
First If you move turntable, the signal data of mouse is transferred to the arduino. The arduino is used to input data into six servo motors. And then, The stewart platform changes posture according to your hand movement.

EXPERIMENT_12
Mouse and DJ Turntable
This is main system for interactive performance. I use a mechanical mouse. It can be used in combination with other system. It is a useful device and has a very simple motion system. The mouse on the left turntable is y-axis.The mouse on the right turntable is x-axis.
Turntable and Mouse
The ball mouse has two freely rotating rollers. They are located 90 degrees apart. One roller detects the forward–backward motion of the mouse and other the left–right motion. Opposite the two rollers is a third one (white, in the photo, at 45 degrees) that is spring loaded to push the ball against the other two rollers. Each roller is on the same shaft as an encoder wheel that has slotted edges; the slots interrupt infrared light beams to generate electrical pulses that represent wheel movement. Each wheel's disc, however, has a pair of light beams, located so that a given beam becomes interrupted, or again starts to pass light freely, when the other beam of the pair is about halfway between changes.
The data of mouse position is used to operating a actuator. Example these are servo motor and vibration motor and stepping motor. In this final project, The servo motor is used to making a movement.
An actuator is a type of motor that is responsible for moving or controlling a mechanism or system. It is operated by a source of energy, typically electric current, hydraulic fluid pressure, or pneumatic pressure, and converts that energy into motion. An actuator is the mechanism by which a control system acts upon an environment. The control system can be simple (a fixed mechanical or electronic system), software-based (e.g. a printer driver, robot control system), a human, or any other input.
X-Axis
Y-Axis
I test a movement of mouse using a adobe illustrator. A Mouse works well for this.

EXPERIMENT_10
Solving the problem
In the past experiments, The box have some problems. It is about a weight. So I need to look at ways of lightening that box. I change the size of box. So The new box is smaller and lighter.
