Creating Mechanism
Robot movements can be defined through the manipulation of inverse kinematic simulations, but this is not the case with a mechanism.Mechanism movements can only be defined through the manipulation of individual joint values. While with a Robot, we can also define through Cartesian position.
(So for a mechanism, we do not need to import a robot, we can make our own cad objects)
Make a cylinder with I command
Change name to - Top
Make another cylinder with I command
This is what we get
Make a box with I command
Change the color of this box to red, rename part and the bottom cylinder = base>>part is child and attach to top as parent
Part = child and Top = parent
Select base>>create>>mechanism>>auxiliary axis - 1
Now create joint
Base is parent>>top is child
A rotational joint is also created
View Pendent
By moving the pendent, the top is moving.
Another position (When we do not have a robot, then we have to make a mechanism).
Lets learn GP`s >> go to extreme position
Learn GP>>no path>>ok
Six GP`s have been made
Lets create a path>> path>>right click>>new path
Name Path1>>manual>>ok
In CAD View>>Drag the GP`s into the Path, they will get copied
Right click base>>simulate (It becomes active)
Simulation>>play simulation
The table top starts moving>> it goes to starting position>>then to each GP.
Lets make animation>>simulate>>Simulate options (we can now play it any where)
This dialog box opens
Click >>create animation, optimise AVI creation, actual size
Animation>>select name>>Active animation
Simulate>>play simulation>>In compression box Microsoft video1>>ok (when the simulation is running, it is actually being recorded also)
Simulation>>play animation
Save as the file at a different location
Select a GP in path>>right click>>properties>change speed in %
Click no or yes, if you want the changes to come in animation
Now again play the simulation
Path >> new path
Path2>> Automatic generic
This dialog box opens
This works with a robot
