Robots in the future

Nanotechnology. How tiny robots might act inside our bodies in the future.
Over the next ten years, breakthroughs in nanotechnology may help us build better and smaller machines.

A nanometre is just one-millionth of a millimetre in length and nanotechnology involves studying and working with materials on an ultra-small scale.

Using nanotechnology, scientists have created a tiny walking nanobot, using only the building blocks of life: DNA.

The microscopic walker, which is only 10 nanometres long, uses its legs to move along a footpath.

Nanotechnology could also lead to a range of materials with new qualities such as stay-clean glass and magnetic liquids.

There may also be breakthroughs from scientists trying to implant computer programs into living creatures - known as wetware.

This technology could help people with false arms or legs to move them just by thinking about it.
