Spider trained to jump on demand

A spider has been trained to jump on demand for the first time paving the way to a new generation of agile micro-robots. Scientists unlocked the secrets of how some predatory spiders hunt their prey by successfully training one they called Kim to jump different distances and heights. The study, conducted by Manchester University researchers, is the most advanced of its kind and the first to use 3D CT scanning and high-speed, high-resolution cameras to record and analyse a spider's movement and behaviour.
