Omron TM Series: Landmark Feature

In this video, Brad Vorrie introduces us to the Landmark feature on the Omron TM Series Collaborative Robot.

The landmark feature of the Omron TM robot is designed to re-orient the robot’s taught positions based on the position of the landmark. The landmark is a pre-taught image so the onboard camera will know how the robot is positioned relative to the work cell based on the captured size and rotation of the image.

This feature is so useful because you can simply roll the robot up to a work cell and not have to precisely measure the position. You simply put the robot in a relative position and let the robot correct itself. The robot not only knows X and Y position, but it knows rotation, depth, pitch, and roll.

Setup is simple. Insert a vision block by pressing the vision button on the robot. Press the edit button on the vision block. Press the arrow then the + button and give the vision block a name. If you need to adjust the camera image, press camera kit. This will allow you to adjust shutter timer, gain, white balance and focus. Press Save.

Now press the back arrow and go into task designer and choose landmark alignment. For this example, we are going to choose fixed. At this point in time, you are going to want to move the robot to the anticipated landmark position. Please note, the closer the robot is to the landmark, the more accurate it is going to be. Press Next. If a green box highlights the landmark and provides coordinates, the camera has successfully found the landmark. Press the save button in the upper left corner. Follow the prompts to save. Use the back button to return to the main project page.

Next, pick the first point you want the robot to move to. Press the free button and move the robot. Once in place, press the point button to save. Notice that an eye mark is labeled on the point block. This indicates that this point is based off the vision base. If you want all the rest of your points to be vision based, choose your saved landmark base here.

Let’s try it out.

The robot stops to look for the landmark. Once the landmark is found, it will go to the vision-based position. Now as I rotate the table you can see the robot re-adjusts itself based on the rotation of the landmark.

As you can see the onboard vision with the Omron TM robot is an extremely useful tool. It allows for extreme flexibility and reliability.
