Digital Fabrication

-David Oliva

These webpages are other blogs that have digital fabricated projects that are somewhat related to what we are doing in class. Take a look at them if you need some ideas.

This website belonging to the Institude for Advanced Architecture of Catalonia, http://www.iaac.net/web/en/index.php, has numerous projects that are related to what we are doing in class.

contains a script that was used to create the physical model shown on the page. I have yet to test the script to determine if it useful but I will let you know if it does.

Grasshopper and Other

-David Oliva, Derek Lockhart

To recap the presentation on Grasshopper in case something happens to your installation and need to reinstall, this is the website to access information on Grasshopper: http://en.wiki.mcneel.com/default.aspx/McNeel/ExplicitHistoryPluginMainPage.html.
All you need an email address to download the Grasshopper plugin. Just simply run the download to install it.

Another web page to access some tutorials and some more information about Grasshopper is http://grasshopper.rhino3d.com/.

The two websites that Shai mentioned in class are http://www.materialsystems.org/ and http://designreform.net/. On designreform.net located on the right side of the page under categories are the tutorials.

The site that I briefly showed, http://nao.eu.com/index.php/2008/12/20/grasshopper-tutorial-by-nao-parametrise-a-tower/, is the tutorial of the parametric tower. If you happen to go to the home page, http://nao.eu.com/, and take a glance of the stuff that is posted you will find some interesting stuff. Some of the stuff is related to design (like the 24k gold coated Mac) and there is also more Grasshopper related material.

Robotics

Physical Computing

Building interactive physical systems by the use of software and hardware that can sense and respond to the analog world

• Uses sensors and microcontrollers


• Inputs information to specified software to that sensor
  
• Controls motors, servos, lighting and other hardware similar to these
  
  

Types of Sensors

http://www.robotshop.us/sensors.html

Photo Transistor

Pressur Sensor Photo Diode PIR Sensor

Ultrasonic range finder

Vibration/Tilt Switch

Sensors
Photodiode- Has the capability of turning light into current or voltage Price- 4 pkg $.99
Uses-

Pressure Sensor- measures various types of pressure, can be pressure caused by: gases, water, and other liquids Price- $1.49
Uses-

Passive InfraRed Sensor (PIR) - An electronic device that measures infrared light. Motion is detected when an infrared source with one temperature passes infront of another object
Price- $.99
Uses-

Phototransistor-

Vibration/Tilt switch- small movement, shaking or vibrating, is used to activate some type of action. Used in blinking sneakers and vibrating car alarms Price-$1.00
Uses-

Hall Effect Magnetic Sensor- is activated when a magnet is brought near it
Price- 4pkg $2.00

Robotics Terminology

Autonomous - not subject to control from outside; self governing; independent
Calibrate - Determine, check, or rectify the graduation of (any instrumant giving quantative measurments)
Ultrasonic - acoustic frequencies above the range audible to the human ear or above 20,000 Hz (hertz)
Biomechanics - developent of prostheses
Electromechanical - relating to a mechanical device or systhem that is actuated or controlled by electricity
Actuator - the "muscles" of a robot, the parts which transfer stored energy into movement
Manipulation - the "hands" of robot or the part that connects to the actuator
Locomotion - How a robot moves over terrain; apparatus equivelant to legs
Dynamics/Kinematics - branch of mechanics dealing with motion and equillibreum of a system

Electrical Terminology

Ampere - Unit of electric current
Volts - international system unit of electric potential and electromotive force
Watts - international system unit of power equal to 1 Joule per second
Capacitor - device for accumilating and holding a charge of electricity, consisting of two equally charged surfaces having opposite signs and seperated by a dielectric
Solenoid - an electric conductor wound as a helix with small pitch, or as two or more coaxil helices, so that current through the conductor establishes a magnetic field within the conductor
Resistor - a device used to control current in an electric curcuit by providing resistance
Current - electricity flowing through a curcuit
Circuit - complete path of electric current; a journey begining and ending at the same place.
