What can I use to cast a mold from stone without hurting the stone?

disciple

I'm new to this, but does anyone know what medium I would use to make a mold from a stone. In other words, There is an old building with a beautiful design sculpted in to it. I want to copy this design. I know there is a material out there that I can press against the original design and make a mold of it and then cast the design in plaster. I just don't know what material I would use to do this without hurting the stone.... Help!!!

Answer
I think the sculpey or any clay will work. If you use normal clay, any residue left will dissolve in the next rain, just don't use brown clay on light stone... if you use water based clay you would have to cast your plaster into the mold while the clay is still wet.
As the clay won't be very stable just on its own, you should consider making a mother mold on top of that. That is a hard shell, which just gives support to the soft part of your mold so it doesn't deform. It depends on the size of what you want to copy if you need it. You could make the mothermold from plaster bandages, but don't put plaster directly on the stone.
Before you start, consider carefully the shape of what you want to copy and where undercuts are and where you have to put in parting lines. What technique you use for mold making really depends on the exact shape of what you want to copy. If the structure is something complicated, you may want to practice how to make molds from more simple structures first so you are aware what causes problems and get some experience in how to solve them.

Another completely contact free method is if you happen to be at a university where they have a 3D laser scanning camera you can borrow, you could use the 3D laser scanner then make a model of your structure in the computer from the scans. That you could print out using a 3D printer. that way you can scale the model to any size (though anything large will be expensive to print)

In what ways do robots help humans?

In what ways? do they make our jobs easier. and how do they help us

Answer
Contemporary uses
Main articles: Industrial robot and Domestic robot

Robots can be placed into roughly two classifications based on the type of job they do. The first category includes tasks which a robot can do better than a human. Here, robots can increase productivity, accuracy, and endurance. The second category consists of dirty, dangerous or dull jobs where it is desirable to replace human labor with robotics.


[edit] Increased productivity, accuracy, and endurance
A Pick and Place robot in a factory

Many factory jobs are now performed by robots. This has led to cheaper mass-produced goods, including automobiles and electronics. Stationary manipulators used in factories have become the largest market for robots. In 2006, there were an estimated 3,540,000 service robots in use, and an estimated 950,000 industrial robots. [35] A different estimate counted more than one million robots in operation worldwide in the first half of 2008, with roughly half in Asia, 32% in Europe, 16% in North America, 1% in Australasia and 1% in Africa.[36]

Some examples of factory robots:

* Car production: Over the last three decades automobile factories have become dominated by robots. A typical factory contains hundreds of industrial robots working on fully automated production lines, with one robot for every ten human workers. On an automated production line, a vehicle chassis on a conveyor is welded, glued, painted and finally assembled at a sequence of robot stations.
* Packaging: Industrial robots are also used extensively for palletizing and packaging of manufactured goods, for example for rapidly taking drink cartons from the end of a conveyor belt and placing them into boxes, or for loading and unloading machining centers.
* Electronics: Mass-produced printed circuit boards (PCBs) are almost exclusively manufactured by pick-and-place robots, typically with SCARA manipulators, which remove tiny electronic components from strips or trays, and place them on to PCBs with great accuracy.[37] Such robots can place hundreds of thousands of components per hour, far out-performing a human in speed, accuracy, and reliability.[38]

Automated guided vehicle carrying medical supplies and records

* Automated guided vehicles (AGVs): Mobile robots, following markers or wires in the floor, or using vision[39] or lasers, are used to transport goods around large facilities, such as warehouses, container ports, or hospitals.[40]

*
o Early AGV-Style Robots were limited to tasks that could be accurately defined and had to be performed the same way every time. Very little feedback or intelligence was required, and the robots needed only the most basic exteroceptors (sensors). The limitations of these AGVs are that their paths are not easily altered and they cannot alter their paths if obstacles block them. If one AGV breaks down, it may stop the entire operation.

*
o Interim AGV-Technologies developed that deploy triangulation from beacons or bar code grids for scanning on the floor or ceiling. In most factories, triangulation systems tend to require moderate to high maintenance, such as daily cleaning of all beacons or bar codes. Also, if a tall pallet or large vehicle blocks beacons or a bar code is marred, AGVs may become lost. Often such AGVs are designed to be used in human-free environments.

*
o Newer AGVs such as the Speci-Minder,[41] ADAM, [42] Tug[43] and PatrolBot Gofer[44] are designed for people-friendly workspaces. They navigate by recognizing natural features. 3D scanners or other means of sensing the environment in two or three dimensions help to eliminate cumulative errors in dead-reckoning calculations of the AGV's current position. Some AGVs can create maps of their environment using scanning lasers with simultaneous localization and mapping (SLAM) and use those maps to navigate in real time with other path planning and obstacle avoidance algorithms. They are able to operate in complex environments and perform non-repetitive and non-sequential tasks such as transporting photomasks in a semiconductor lab, specimens in hospitals and goods in warehouses. For dynamic areas, such as warehouses full of pallets, AGVs require additional strategies. Only a few vision-augmented systems currently claim to be able to navigate reliably in such environments.

[edit] Dirty, dangerous, dull or inaccessible tasks

There are many jobs which humans would rather leave to robots.

Help with building RGB LASER Scanner?

3d scanner laser line image

Matt

Hi there previously I have build some laser spyro projects but I have absolutely no idea about RGB LASER Scanners can someone please help.I have tried to find every possible information on the internet but I guess I need to start from the basics.
Thanks : )

Answer
there are several ways to do this, each involving different amounts of electro-optics in digital and analog forms.

you'll have to decide what you're scanning. is it 2D? 3D? still? or live-action?

in the easiest of cases, you can probably find an old photocopy machine and see how that works.

in the hardest case, your scanning data might become real-time input to a vehicle that must navigate through its environment.

so you will have a scanning beam, and a detector.

the scanning beam is a laser; you're interested in tri-colour, so this is either three lasers of different wavelengths, or it is a white-light laser that you will later filter. true white-light lasers are pulsed. if the pulse rate is really high (eg: in the millions of pulses/second), then each pulse could represent a pixel, and still have a mean free path of several meters.

the detector is a CCD photoreceptor, (or a whole lot of them), filtered to pass the desired wavelength(s). you can choose to capture:
a) a stream of individual bounces without regard to the focus;
b) a whole scan line into a buffer at once; or
c) a whole 2D frame into a buffer at once.
each method implies different mechano-optics, with a) being the simplest, mechanically. additionally, it may be possible to convert some digital cameras to use for this purpose.

to scan, you'll draw a point of light across a remote object, detecting the intensity of what bounces back. if this is not a range-finding device, then the outbound signal may be constant-intensity; but to detect distance, velocity, or absorption spectra, you will have to do some optical and/or high-speed tricks (sub-nanosecond processing is hard) involving correlating the outbound signal to the returned signal, to build a profile.

photon time-of-flight would indicate distance, (1 ns is about 30cm), and doppler shift would indicate speed.

to detect time of flight implies very high sensitivity and probably high frame rate, too.

to detect doppler shift and spectral lines would require that the returned beam travel through a prism, to give angular separation to the photon stream by wavelength. in this case, you'll always be scanning into a buffer, whose width covers the returned wavelengths.

each scan line would be drawn using a mirror that can tilt and swivel on two orthogonal axes. (or a pair of mirrors, arranged to swivel on orthogonal axes). controlling the mirror(s) will be subtle and delicate, because vibration may cause some fuzz in where the point gets drawn.
(think of a mechanism very similar to a DVD reader, for instance.)

for noise control, you'll want to distinguish between ambient light and returned signal.

Help with VB6 to VB.NET conversion!?

3d scanner laser line image

RjSowden

I'm asking this because I don't know anything about VB6 (It was around before I was born), and theirs no point in me having to spend 6 weeks learning all the functions ect... when their are others with a much better understanding who will get it right first time.

I need to convert this code :

Private WindowWidth
Private WindowHeight
Private threshold
Private rgbvalue

Private Sub Form_Load()
'
WindowWidth = 320
WindowHeight = 240
myy = 1

End Sub

Private Sub Timer1_Timer()

Dim R As Long
Dim G As Long
Dim B As Long

Dim myx
Dim myy
Dim rgbvalue

threshold = Slider1.Value '1600000 '3876853 'Reverse BGR hex value for a red colour
Text1.Text = threshold
threshold = 1585276

myy = 1

mynumber = 1
mytextnumber$ = mynumber

Form1.Picture3 = LoadPicture("D:\Colin Ord\3d scanner\3D Scanner RT 2009\rgb.jpg")

mytextnumber$ = "D:\Colin Ord\3d scanner\3D Scanner RT 2009\" & "1.jpg"

On Error GoTo ErrorHandler

ErrorHandler:
If Err.Number = 53 Or 481 Then
'Debug.Print "Some problem with loading jpg image."
Resume Next
End If

Picture1 = LoadPicture(mytextnumber$)

For xcnt = 0 To WindowWidth
If Picture1.Point(xcnt, 30) > threshold Then '100000 Then
origin = xcnt

GoTo start:
End If
Next

start:

For myy = 0 To WindowHeight

For myx = 0 To WindowWidth
If Picture1.Point(myx, myy) > threshold Then '1000000 Then
GoTo here:
End If
Next

here:

Picture1.PSet (myx, myy), RGB(255, 255, 0)
Picture1.Line (0, 30)-(WindowWidth, 30), RGB(0, 255, 0)

If Form1.Picture3.Point(myx, myy) > 100000 Then
rgbvalue = Form1.Picture3.Point(myx, myy)
End If

rotx = origin - myx
roty = myy * 2
rotz = (rotx + myx) / 2

'Output file
Open "D:\Colin Ord\3d scanner\3D Scanner RT 2009\freescanRGB_object_01.asc" For Append As #1

'Read RGB values from hex pixel colour
R = &HFF& And rgbvalue
G = (&HFF00& And rgbvalue) \ 256
B = (&HFF0000 And rgbvalue) \ 65536

' Aligns scan with laser angle offset and skew
rot = 30 * 0.0174532 '57.29577951
rotzz = rotz * Cos(rot) - myx * Sin(rot)
rotxx = rotz * Sin(rot) + myx * Cos(rot)
rotyy = roty 'myy '/ 2

'create the vertex string - 'X Y Z R G B'
Print #1, ((rotxx + rotx) & " " & (rotyy / 2) & " " & ((rotzz * -2) * 2) & " " & R & " " & G & " " & B)
Close #1

'LASER LINE PREVIEW BOX- Draws each vertex with a red dot.
Picture2.PSet (myx, myy), RGB(255, 0, 0)
Next

End Sub

...Into VB.NET So I can tweak it and put it into my own application. I got it from text right off the internet, so I cant try to import it into .NET and let that convert it for me, because I cant save it. Thanks to everyone who can give advice, and I'll definitely give out a best answer. Thanks so much again in advance!
I do know that the Timer class doe's need a handler. I know VB.NET well. Picture3 defines a picture box control

Answer
It looks like either your code is not complete or there is a reference library that you're going to need for this.

Form1.Picture3 = LoadPicture("D:\Colin Ord\3d scanner\3D Scanner RT 2009\rgb.jpg")

LoadPicture is not defined anywhere in the code you posted. There is also nothing listed here to make the Timer1_Timer sub run.

You're going to have to find the missing parts to this project if you want to use it as written. Otherwise you're going to have to disect it pulling out bits & pieces to make it work for you.
