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
