Cassie el robot ciego aprende a detectar escalones por primera vez.
Ingenieros de EE. UU. han creado un robot que puede subir escaleras fácilmente en la oscuridad.
Cassie el robot, subió los escalones en la Universidad Estatal de Oregon con un 80 por ciento de éxito. Todo sin ojos ni otros sensores.
El robot bípedo fue entrenado para usar la propiocepción o conciencia corporal para andar por superficies irregulares.
Los investigadores dicen que esto es importante si la niebla, la luz tenue u otros factores limitan la habilidad visual de un robot.
Cassie el robot fue desarrollado por el Laboratorio de Robótica Dinámica de la Universidad Estatal de Oregon en 2017.
No tiene cabeza pero sus caderas tienen tres grados de movimiento, lo que le permite mover sus piernas hacia adelante y hacia atrás, de lado a lado, y también rotarlas al mismo tiempo.
Además, los tobillos eléctricos de Cassie le permiten pararse en su lugar sin tener que mover constantemente los pies y cambiar su peso.
Cassie está clasificado como un caminante dinámico con un andar más suave y más parecido al humano que el típico autómata ruidoso. De este modo se pretende hacerlo un experto en atravesar terrenos complejos. Bueno, complejos desde el punto de vista de un robot.
Cassie ya resistió otros retos extremos, como caminar a través del fuego y montar con éxito un Segway.
Los investigadores del estado de Oregon estaban interesados en entrenar a Cassie para subir escaleras ciegamente, es decir, sin visión por computadora u otros sensores.
Los robots han podido subir escaleras desde hace mucho tiempo utilizando cámaras y visión por computadora. Pero ciertas condiciones, como la iluminación tenue, no siempre son ideales para un reconocimiento visual.
Querían que Cassie el robot subiera y bajara los escalones usando solo su propiocepción de la misma manera que tú o yo podríamos deslizarnos hasta el sótano por la noche.
Sin embargo, antes de que Cassie fuera puesta a prueba, los ingenieros lo entrenaron virtualmente.
Usando un simulador, le enseñaron a Cassie cómo manejar una serie de situaciones, incluidas escaleras y terreno plano, evitando así muchas caídas y choques, especialmente al principio del entrenamiento, dijo el equipo.
En 10 ensayos, Cassie tuvo una tasa de éxito del 80 por ciento al subir las escaleras y del 100 por ciento al bajar.
Hasta donde sabemos, este es el primer controlador para un robot bípedo a escala humana capaz de atravesar de manera confiable una variedad de escaleras del mundo real y otros incovenientes similares a escalones usando solo la propiocepción ‘, dijeron los investigadores.
En última instancia, Agility Robotics ve al robot Cassie como una combinación de repartidor y perro mascota, que puede subir corriendo los escalones para entregar paquetes en la puerta de su casa, incluso si hay niebla o está oscuro.
A partir de octubre, Agility ha recaudado $ 29 millones de dólares en fondos, con Sony y TDK entre sus patrocinadores.
