Week+4


 * REMEMBER:** A robot must ** sense ** its environment, have a **plan** of how to react to its environment, and **act**.

=How Fast?=

**Overview:** To accurately be able to command the robot, you need to understand how fast it can go and what properties may change its performance. NASA has requested a detailed report, supported by data that you have gathered from your robot.

=Flowcharting=

Goal:
Use a flowchart to break down a large project into a series of more manageable tasks that can be more easily completed.

=Help! I'm Stuck=

**Overview:** While on NXTopia, your robt will undoubtedly come up against some terrains that are too difficult for the robot to navigate. NASA is worried about a particular chasm near the drop zone where the robot could get trapped. They have asked that you demonstrate your robots ability to detect such an obstacle and navigate out of the chasm.

Activity:

 * 1) Build a bumper (with a touch sensor) to be attached to the front of your robot.
 * 2) There are several steps we would like to make in order to solve this problem. Each program should be done individually and demonstrated to a teacher before moving on. We would like the robot to:
 * Drive forward until an object is detected, then stop.
 * Shout 'ouch!' when you hit the object
 * Turn around when you hit the object
 * Repeat this action until you find your way out of the chasm

**Wait for Touch Block**: Wait until the touch sensor has been pressed before moving to the next block.
