La fotografía es un robot desarrollado con tecnología suiza -si es igual de buena que los relojes el robot llegará lejos bautizado como Octopus, sus brazos móviles le permiten moverse autónomamente superando obstáculos y variaciones en el terreno, sin intervención humana. Una serie de sensores le van dando la información adecuada para que el robot identifique el problema y los cuatro brazos móviles se articulen de la forma adecuada. Este tipo de tecnología robótica tiene multiples aplicaciones allá donde el ser humano no puede llegar, desde lugares de dificil acceso como estrechas tuberías, hasta llegar a vehículos espaciales que tomen muestras del suelo de otros planetas. El robot ha sido desarrollado por una Universidad tecnológica de Zurich (la ETHZ).En el siguiente dibujo está el ejemplo explicativo de los pasos que utiliza el robot para superar un escalón.
Step climbing with Octopus
1. The robot is rolling in his flat terrain configuration with the centre of gravity between the central wheels.
2. The front wheel touches the step.
3. The front forearm raises as the robot continue its advance until the second wheel touches the step.
4. The rear forearm motor and the motorized parallelogram act to raise the body, the front arm, the front forearm and the two front wheels. The front forearm motor acts so that the front wheel follows the terrain profile and reaches the horizontal part of the step.
5. The robot continues its advance until the third wheel touches the step.
6. At this moment the two forearm motors act to raise the body, the two arms and the two central wheels. The weight of the robot is shared between the two external wheels.
7. The second wheel reaches the horizontal part of the step before the last wheel touches the vertical part of the step. The weight of the robot is shared between the two front wheels and the last wheel.
8. The front forearm motor and the motorized parallelogram act to raise the body, the rear arm, the rear forearm and the rear wheels. The weight of the robot is shared between the two front wheels. We remark that the position of the COG is outside the two contact points of the front wheels. In this case some friction on the front wheels is necessary to prevent falling back.
9. The third wheel reaches the horizontal part of the step. The rear forearm rises until the last wheel reaches the summit of the step.
10. The climbing sequence is over.
