this shows why using the tutch sensor is a good idea to detect walls

it seems that the robot is using a sensor on top of itself. this can be helpful because it can detect cilffs faster but it will detect them too soon and turn away. therefore, it won't clean everything. in my opinion we should place the sesors in front and not on the top

the video shows that when the light sensor reads a certain value then it pick it up...

*initiates the motor to turn on which lifts up the object

strategy sumo

i don't see how that robot can go on the offensive side

an NXT doing a maze in only a minute 35

Tufts University Center for Engineering Education and Outreach In this activity, we will learn how to create a robot that follows a line on the ground. It will use one light sensor to sense where the line is, and use this to control the motors to steer the car and stay on the line.

I know it doesn't say much but this single-motored nxt can rotate it's ultrasonic sensor allowing it to see multiple walls at once

i thing that this proves that a big plow in the front may be a good idea

Jarid had posted a link as well with the plow as a v shape. this would work if your going for pushing someone off the table

some good ideas for design

Ithink this design minus the treds of course would be a great idea.

this has some good explinations of designs

The bottom of this page explains how to create differnent gear ratios and how they work

they are using a diffrent program

we could make the program in labview, they were just using a piece of wood on books.

This shows us the torque of the motor. Yes we have 9 volt batterys, the bottom of the page next to a picture are some gear ratios.

it shows how we can adjust the gear ratios to give the robot more or less power while driving

how to data log

how cliff detection works and what kind of sensors are used

this is good to know for when you need to pick a spot to but your sensors
