NXT Modular Test Vehicle (MTV) - 3 views

shared by Alexander Sarkis on 06 Dec 11 - Cached

The Drive Wheels module is designed to make it easy to change the gears used so that you can experiment with different gear combinations.  Different combinations will result in different gear ratios, which will have a big effect on the speed and power of your robot.   The faster gear combinations will make the robot go faster but have less power, which will make it harder to turn and carry loads, and note that faster robots are also typically less accurate.

HowStuffWorks "Understanding a Gear Ratio" - 3 views

Understanding the concept of the gear ratio is easy if you understand the concept of the circumference of a circle. Keep in mind that the circumference of a circle is equal to the diameter of the circle multiplied by Pi (Pi is equal to 3.14159...). Therefore, if you have a circle or a gear with a diameter of one inch, the circumference of that circle will be 3.14159 inches.

FOLLOWING and US CORNERING behaviors were added to this robot with no additional sensors to demonstrate building on top of existing behaviors and adding more robust wall following and area coverage in multiple chambers separated by a small door.

WALL FOLLOWING was introduced in this version of the robot utilizing the Lego Ultrasonic sensor to allow the robot a better chance of covering the area along a wall. bbAreaRover2.zip

we don't have the EOPD sensor that this robot does in the video but it is similar to our light sensors.
