Simulating the robot on the field

  • There are no posts on any of the forum pages about simulating robots on a field
  • The only possible solution is drawing a line on the field, and have the robot move along the line. While it is moing, we can also have the wheels moving.
  • The other possible way, is to just use video editing tools to make the robot look like it is moving across the field.

 

Measure Values in PTC Parametric –

  • Through the mechanism analysis feature of PTC Parametric, we can set a certain motor or servo to move a certain rotations for a certain amount of time.
  • Then using the measure results tool, we can graph and look at the results and return values of these the rotations we set the servo or motor to move.

 

 

  • Using the mechanism analysis tool, we can create simulations and movements of servos
    • Then we can use the measure tool to select a certain point on the robot
      • You can choose as many points you want
    • Then with the measure tool, you can find how the movement, velocity, acceleration, etc of that point of the robot
    • From here you can create a graph.

 

 

 

 

We will now use center of gravity to help us simulate our robot, for example to see if it will fall off a ramp.
