In the latest robot developments, Steve Caplin discusses robots that can mine and cut overgrown trees beside railways, as well as those which have established a world record for synchronised dancing. Astronauts will now be able to take eyedrops with them into space. Scientists in Singapore have developed a screen that can be woven into the sleeve of a sweater. Others have found a way to send smells via the internet. The new Virgin Galactic plane will take half a dozen passengers to the edge of space: there's a waiting list of 675 even though it costs $850,000. A bitcoin miner can heat your hot water tank at the same time as it mines. And an AirTag has been used to locate a thief stealing valuable stones from old walls.
