Investigate

Guiding Question:

How can we use the internet to communicate when disaster strikes a community?

Identify Hazards

The first step in emergency planning is to identify hazards the school may face. These fall into three main categories:

1. Natural events, such as severe weather, earthquakes and epidemics.
2. Technological events, including fire, explosion and power outages.
3. Human-caused events, such as terrorism, sabotage or a violent incident.

The past is often a good predictor of the future, so start by looking at the types of emergencies local schools have faced over the years.

Hardware:
Mobile phone:
A really helpful mobile phone is the Blackberry phone because what is good about all kinds of mobile phone not just blackberry is that if we are hit by a hurricane and experience a 9-day power/land line phone outage.


Computer:
Researchers have successfully tested a system that can replace a cellular tower's room full of communications hardware with a single desk-top style computer, making the technology affordable for small, rural communities.

Radio:
We can use the radio because if anyone or anybody who is listening to the new on the radio, of course they will announce that maybe a hurricane is on the way and that go to the shelter house. Then you can use the land line or the home phone that is more secure than the mobile phone which can be very dangerous.

Evaluation

What worked well and what didn't work well?
There are a couple of things that worked well, and a couple that didn't work well.

What worked well?
  • we made the robot follow a white line.
  • making in park
  • we built our robots several times.
  • some people already know how to build them without looking at the book.
  • we used windlogo to help us too.

What didn't work well?

  • we forgot to plan it.
  • some people said that they wanted the robot to wash their face, legs and hands.
  • some people wanted it to design weird thing.
  • we wern't able to design a robot.

Investigation

Reflection about what we did in the design cycle

Last Thursday we had to build a robot that was very nice, but , we forgot to design it or plan it we just went frominvestigating straight to create with no planning and designing. we didn't know what kind we had to do and the thing we had to do it with was Lego.

What is a Robot?

My defenition:

A robot is an automous(independent) machine that uses power,sensors,actuators,processors and batries and is build to do in danger situations in the environment. A robot doesn't need food or drinks, doesn't sleep and works 24x7x365.A robot is fast and a high quiality, and there are many diffrent types of robot's and have their own performance.

What makes a robot workes?

A robot is made up of the very same components. A typical robot has a movable physical structure, a motor of some sort, a sensor system, a power supply and a computer "brain" that controls all of these elements. Essentially, robots are man-made versions of animal life -- they are machines that replicate human and animal behavior.
In this article, we'll explore the basic concept of robotics and find out how robots do what they do.Joseph Engelberger, a pioneer in industrial robotics, once remarked "I can't define a robot, but I know one when I see one." If you consider all the different machines people call robots, you can see that it's nearly impossible to come up with a comprehensive definition. Everybody has a different idea of what constitutes a robot.
You've probably heard of several of these famous robots:
R2D2 and C-3PO: The intelligent, speaking robots with loads of personality in the "Star Wars" movies
Sony's AIBO: A robotic dog that learns through human interaction
Honda's ASIMO: A robot that can walk on two legs like a person
Industrial robots: Automated machines that work on assembly lines
Data: The almost human android from "Star Trek"
BattleBots: The remote control fighters on Comedy Central
Bomb-defusing robots
NASA's Mars rovers
HAL: The ship's computer in Stanley Kubrick's "2001: A Space Odyssey"
Robomower: The lawn-mowing robot from Friendly Robotics
The Robot in the television series "Lost in Space"
MindStorms: LEGO's popular robotics kit
