I’ve got this theory that every stupid idea is a great idea waiting to happen – all it takes is a different perspective.
So it is with bristlebots – I’ve touched on this before with the thing where the bristlebot turned into a possible engine for a space elevator.
Well another one’s turned up. Making a tiny bristlebot to deliver drugs to tumours.
It’s about 1mm wide by 1cm long and is powered with an external vibrating magnetic field. Apparently there’s plans to mount a camera on it, which is something I went on about before, and everyone thought I was mad etc. Microbial Safari.
Of course this particular robot is a direct nick from nature – foxtails which (in NZ at least) are the bane of dog owner’s lives because they get stuck between their toes, and like these robots, can only go in one direction – deeper.
Nasty little shits they are. Quite intriguing to play with though – they’re actually covered in micro-barbs to accentuate the affect. Kindof like one-way velcro.
