We study the movements of the machines we build and improve on them through common means. We are designing the complexities of machines to build with easy materials to use. Through the common man, complex machines can be made with precision and detail to produce a complex final product.Archieshttp://www.blogger.com/profile/02105384578435660246noreply@blogger.comBlogger13125tag:blogger.com,1999:blog-650880503069639016.post-71222794761661821572012-05-09T15:57:00.000-07:002012-05-09T16:02:19.099-07:00LEGO RCX DOT MACHINE<div class="separator" style="clear: both; text-align: center;">

This is the 3rd base fro my Drawing Robot. This base lifts the pen up and pushes it back down at a high speed to create dashes while it drives forward. A motor in the center of the robot drives a gear that turns 2 gears that are connected to each side of the robot. The gears that hold the pen are driven in opposite directions. The bottom gear on each side is the drive gear then a small gear is placed between the top and bottom gears to make them turn in unison and in the same direction.<br />

Here is the second base to LEGO RCX. This base holds up to three pens. The control is the same as the first LEGO RCX Robot. This robot the pens are the front wheels and the robot is driven by the two rear wheels.<br />

<b>LEGO RCX TURNTABLE ROBOT</b></h2>
<div class="separator" style="clear: both; text-align: left;">
This Robot Is designed to draw in a circle as it drives forward. It is a
take off of my First LEGO Machine where it was controlled by one
motor. This Robot has 3 motors and 2 touch sensors. It is controlled
by a LEGO RCX 2.0 Programmable Brick. 2 of the motors control the drive
of the tracks. The tracks are controlled independently. The third
motor controls the pen. The touch sensors are located in the front and
rear of the Robot. The Program for this Robot is designed to drive
forward until the front touch sensor hits the frame of the drawing
area. This tells the Robot to back up strait for one second. Then the
"drivers" side track stops for two seconds while the passenger side
tracks continues to drive backward. After that both tracks drive
backward until the rear touch censer is activated. That causes the
Robot to drive forward for one second then the passenger side track
stops for 2.5 seconds. After that both tracks start driving forward
until the front sensor is activated and the whole process starts again.
The Robot keeps driving back and forth on the paper until someone stops
the program or the battery dies. I have run it non-stop for 15
minutes. Below is a couple of videos of the robot running. <a href="http://1.bp.blogspot.com/-fQg5Han9BHI/T25S-mzA28I/AAAAAAAAAFA/u6qkxbKFqkY/s1600/LEGO+RCX+1+e.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="480" src="http://1.bp.blogspot.com/-fQg5Han9BHI/T25S-mzA28I/AAAAAAAAAFA/u6qkxbKFqkY/s640/LEGO+RCX+1+e.JPG" width="640" /></a></div>

Machine 4 Top</div>
<div style="text-align: left;">
This Machine improved on Machine 3. Instead of having a rubber band as the belt I took a bike chain off one of my old bikes. I also took the gears off the pedals to use in my new machine. This machine keep the chain in tension with the gear-shifter from the back of the bike. This Machine uses all steel connections, bushings, and makeshift bearings. The crank turns both the paper and the arms. The problem with this machine is the smoothness of the cranking and the post that moves side to side and connects the top and bottom arms. This is because of the distance between the two arms. This machine ends up drawing an oval if the paper was stationary. But because the paper turns it draws a rose like shape. </div>

Wooden Machine 3 Bottom</div>
<br />
This Machine improves on both my first and second wooden Machines. In this Machine I used mostly steel connections and bushings. The top wheel moves both the arm and paper. The bottom mechanism stayed mostly the same but was improved by adding threaded rod and bushings. The side to side action was improved also with the addition of steel to the mix. This machine drew a image that looked like a rose window. The only problem with this design was that there was no crank to turn the wheels and the belt was made out of rubber bands and stretched to much when it turned so the paper would change speeds.<br />

<div style="text-align: left;">
<span style="font-size: xx-small;"><span style="font-size: small;">This Machine was the second iteration of my first Wooden Machine. I kept the top action basically the same. On the bottom side of the Machine I put another wheel that held another arm that had a rod and pin in it. The rod and pin are in a slot that moves the rod as the wheel is turned. This causes the rod to move in a slot that was cut into the base. The rod is connected to the top pin and causes the top pin to move side to side. This creates an oval like shape. In this Machine I was also experimenting with the position of the pin on the top wheel. When in the row of hols as pictured above, the pen draws a oval (Bottom picture). When in the holes that are perpendicular to that row, the pen draws a kidney like shape. (Top Picuture</span></span><br />

This is my first wooden Machine. The goal I had for this machine was to make an Oval. After I made the machine I found out that it made more of a balloon like shape. This machine works by turning a wheel. The wheel moves an arm. The arm has a slot in it that a stationary pin is inserted into. The arm also holds the pencil/pen.<br />

<div style="text-align: left;">
This Machine was designed to draw in a circle as it moved forward. The machine is powered by a LEGO Power Functions M-Motor. The tracks are driven by a worm drive that is turning a 24 tooth gear. The Motor also powers a 40 tooth gear that turns a 24 tooth gear on a arm. This arm flips to the right when driving forward. This turns another 24 tooth gear that turns a large pulley on the same axle. The large pulley turns a small pulley with a belt. This small pulley turns another 40 tooth gear on the same axle. The 40 tooth gear then turns another 24 tooth gear, that turns a worm gear on the same axle. The worm gear then turns a turntable that holds the pencil/pen. When driving backward the arm flips to the left. This causes the 24 tooth gear on the arm to spin another 24 tooth gear that is on the same axle as the small pulley and the 40 tooth gear. This causes the worm drive to <span style="background-color: orange;"></span>spin slower then when the machine drives forward.</div>
<div style="text-align: left;">
<br /></div>
<div style="text-align: left;">
When driving forward, the machine draws a series of half circles. (Pictured Below in Middle) When driving backward the machine draws a curved line. (Pictured Below on Bottom) Pictured Below on top is the drawing the machine makes when it draws in both directions with out stopping.<br />
