Our robot "Hammerschlag" (the origin of this name comes from the painting of the company "Hammerschlag") uses three cords which are mounted to the scaffold of the field to move around.
To detect the LED, which is placed on the target platform, two photosensors which are placed at the bottom of our robot are being used. The connection with the robot of the other team Team 09 is being established over wifi. The robot sends a signal to the other robot if the platform has been detected.

To physically connect our robot to the robot of team 09 we use five permanent magnets. Our robot has a mechanism to correct the main emphasis which is changed by the connection of the two robots.

Program sequence

  • 1. Platform detection
  • 2. Docking / tilting
  • 3. Landing

Platform detection

As mentioned in the introduction 2 photosensors are being used for the detection of the LED which is placed on top of the target platform. The five possible positions of the platform are strictly defined and therefore we can search at those specific positions after the LED. The robot which has found the platform will send a signal to the partner teams robot by wify.

Docking and tilting of the two robots

The two robots meet at the center of the field and dock onto each other with permanent magnets. The change of the main emphasis will be sorted out by the tilting mechanism of the robot to maintain stability while in the air. The robot which isnt placed on the side with the platform will then loosen the cords.


The last step for the robots is to move to the platform and try to land on it. A mechanism has been included in our robot to compensate the main emphasis which is changed since there is another robot connected to it. This ensures the stability of the movement until the platform is reached. The two robots will then land on the target platform together.
