Design critic Oliver Wainwright goes behind the scenes at the Robots exhibition at the Science Museum in London. Curator Ling Lee introduces him to some of the most advanced humanoid robots in the world, from a lifelike baby to robots without conscience. She explains the stage that the technology is at, who may use it and how far it has to go.
This robot ray is the most successful artificial animal yet!
The soft rubber body of the #robot ray is made with a 3-D-printed gold skeleton so thin it functions like cartilage. Geneticists adapted rat heart cells so they could respond to light by contracting. Then, they were grown in a carefully arranged pattern on the rubber and around the gold skeleton. Watch the video.
The birth of biohybrid beings
The new engineered animal responds to light so well scientists were able to guide it through an obstacle course 15 times its length using strong and weak light pulses.
The study authors write, “Our ray outperformed existing locomotive biohybrid systems in terms of speed, distance traveled, and durability (six days), demonstrating the potential of self-propelled, phototactically activated tissue-engineered robots.”
What biohybrid mean for robots and artificial intelligence
Science of this type is fundamental for engineering special-purpose creations such as artificial worms that sniff out and eat cancer. Or bionic body parts for those who have suffered accidents or disease. Imagine having little swimmers in your system that rush to the site of a medical emergency such as a stroke. The promise of sensor-rich soft tissue frees robots to move more easily and yet not be cut off from needed input. Sensitized robot soft tissue could perform without the energy-sucking heaviness of metal or the artificial barrier of hard-plastic exoskeletons.
Washington State University researchers have developed a unique, multi-functional smart material that can change shape from heat or light and can assemble and disassemble itself. It is the first time that researchers have been able to combine several smart abilities, including shape memory behavior, light-activated movement, and self-healing behavior, into one material.
