Note: If you have an Hitchnic Color sensor and a Compass Sensor, you can build the Dragster Version 2.0. In the version 2.0 it looks more like a dragster and does not have the light sensor program. And has more features! To get the Dragster Version 2.0 click projects on the top and select it. Please note that Version 2.0 is better than Version 1.0.

Please note that you can replace the light sensor with a colour sensor.

Halloween Candy Delivery Bot Version 1.5

Halloween Candy Delivery Bot

Do you want to make a robot on Halloween? Does that robot that you want to make a robot that delivers Candy? Well if you do then this is the Robot for you.

What you need:

1 Mindstorms NXT Set (retail Version)
1 Lego Mindstorms Education NXT Set

The Idea

Well it was Halloween (2008) I wanted you make a project for Halloween. I had an a idea! (But it was not this project) The idea was that I would build a robot that would hang over my door. When I opened the door I would press the orange button on by remote NXT and the base NXT would start one motor witch I would release the string and drop down right in front of the door. But my front door as not usable. Then I had a second idea (this project) with wheels instead of string. I worked on that project and made it work great but there was one problem. The iPod Touch was not Allowed in the Challenge so I made this Version 1.5 of Halloween Candy Delivery Bot. To see the Version 1.0 of Halloween Candy Delivery Bot you can: Look at the other picture with the iPod Touch.

The Design

Well, this is how a build Halloween Candy Delivery Bot Version 1.5. Well I already had Halloween Candy Delivery Bot Version 1.0 so I just changed the top. But if I started from scratch. I would: Firs

t start with the back wheels/balls. How I got the idea of using balls was from the

Back Wheels (Balls)

The second thing that I worked on is the back wheels (balls) I got the idea when read a Book called The Lego Mindstorms NXT Idea Book. I look at the back of the ‘Beach Buggy Chair’ which used the balls in the set. I tweaked them a and made them work with the Halloween Candy Delivery Bot. If you want to see more pictures of the back they are posted here. To build them use the LDD file. The Lego Digital Designer File does NOT contain the whole project just the back part.

Building the Halloween Delivery Candy Bot

Use LDD File to build Sections then use the steps to connect parts together.

Click Here to download the LDD file to build Halloween Delivery Candy Bot

Step 1: Connect the Technic 5M beam to the Base on both sides.

Step: 2: Connect the Technic 9M beam to the Technic 15M beam on both sides.

Step 3: Take the Axle on one of the motors and slip it threw the 15M beam. Then but a gear on it. (Note: Do this step on both sides.)

Step 4: Build the model using the pictures. How it goes is the wheel, Cross Axle 7M, then Bush for Cross Axle, and a gear.

Step 5: Connect the wheel model that you just build to the Main model, then the Technic 15M beam on the axle ,then add a bush for Cross Axle.  Note: Do this on both sides.

Step 6: Get a box and some scissors or something that cuts cardboard and make sure the box was these things no top/lid, 9.5 cm width, 17.5 cm length, and 9 cm in height.

Step 7: Up the box that you cut out in place and tape it to the model using these areas. After step 7 you are finished building the model.

Step 8: Connect the free beam on the other side of the “X”.

Step 9: Make sure this part looks like the picture below.

Step 10: Connect the part to the model and cut a piece of paper out about the same size as the square and say happy halloween on it then tape it on to the square.  Connect the motors to CB and the touch sensor to 1. Note: if you want more detailed instructions please comment.

Getting Started with the Robot

When you finished building it you can put candy bars in the box in the back on the vehicle and Lays Chips at the front.

Download the two rbt files the left one goes to the remote and the right one goes to the car/model. (The model that you just built) (Note:You should download them one at a time, then rename them because when I uploaded it they where both NXTLogFile as there name.) How to connect the NXTs with bluetooth.

1. (Skip this step if you know that bluetooth is on and discoverable) Go to the Bluetooth menu one the Tribot and make sure it is discoverable and Bluetooth is on.

2. (Skip this step if you have connected with your other NXT before) Use the NXT that is one the remote go to search and search for it click on you other NXT and click one connection one (number one) and click connect. Enter a passkey on both NXT’s (Make sure that they are the same.) Skip the next step.

3. Go to My Contacts click your other NXT then click on Connect.

4. Run the program on the remote NXT

5. Run the other program NXT Here is what you do when you run the program: 1. On the hand held NXT it will say Press Orange button to begin.2. When you the the orange button the NXT on the floor will move 4 rotation or (I think) 1.2 meters I cannot be sure.

P.B.S.B (Portable Back Scratcher Bot)

Here is a Portable Back Scratcher Bot. That means you can get a back scratch, so scroll down and look. There are two different versions of this robot.

What are difference for each version: Well the design of each version. Version one uses only one Mindstorms NXT set while the second version uses two Mindstorms NXT sets.

You need:
A NXT Brick
One or two Mindstorms NXT sets (more detail will come.)
One Accel Sensor (optional)
2 NXT Motor
Accel Sensor:

If you have an Accel Sensor for Hitechnic, attach it to the NXT using port 4 and use the click the link to use the program with a the Accelerometer Sensor.

Motor:
Connect the motors to port C and BThe set up.

1. Start the program
2. Make sure the person that you are back scratch has only skin where you are doing it. (clothes will not work)
2. Press the orange button after you see the message
3. Start putting the wheels on the person back
4. Press the left or right button to change directions (you can do this one forever)
5. Press the grey button to end the program

Notes: IF YOU HAVE THE ACCELEROMETER SENSOR USE THE PROGRAM ON THE LEFT IF YOU DO NOT USE THE ONE ON THE RIGHT. You have to make each version two times. (Scroll down for more info)

Version 1 (two Mindstorms NXT Sets)

Here are the pictures you need to make Version 1. I think I have lots of pictures so try to build it. If you can not please reply to me. Also Connect the motors to C and B. If you have a Accel Sensor a add it to the NXT and put the wire on sensor port 4. Notes: you have to copy the this two times. After you make the first (the top picture)please copy it so you have two. Why do we have to use two sets? Because you need 8 gears and one set only has 6 gears.

After you make the first (the top picture) please copy it so you have two.

The Wheels

You need Wheels to have this Version one and Version two to work. You can use the wheels from the Mindstorms NXT set or Lego Eduction Mindstorms NXt set. Here are the two types of wheels I like.
