Mecha Papp

Mecha Papp

Hilde & Bård Tørdal | 2012

For our show Papp 2.0 at the National Museum of Design and Architecture in Oslo we made Mecha Papp, an oversized Papp on constant vigil around the new Papp artists.

Mecha Papp was a very quick project for us. In one week we started with a pencil drawing, design the chassis and mechanics in Rhino, CNCd the parts, assembled the robot, wrote code and hit the start button.

To move a robot of this size we used the sturdy aluminum motor mount and wheel kit from Parallax with twin HB25 motor controllers and their aluminum caster wheel kit. A linear servo actuator from Servo City lifts the cardboard box and two more oversize servos move the eyes and open the eye lid.

Mecha Papp navigates with line sensors on the floor and three ultrasound sensors to avoid collision with the audience of the show.
