      Hey mee3megemel,

      Scientists and engineers have been able to replace the jobs of organs with robots for decades! Using equipment such as the Iron Lung (used to help people with a nasty disease called Polio breathe), Heart Bypass Machine (which allows surgeons to operate on the heart and keep the patient alive at the same time) and Dialysis (which helps filter blood when people’s kidneys do not work properly). However, all these devices are big and clunky and not designed to fit inside a person’s body.

      So I guess from your question you’re asking which organs can be replaced by mechanical parts? For that there are two examples I can give you.

      The heart being one as it is a pump and there are people trying to replace it with an artificial heart, like this one here: This might be a better option that waiting on a organ donor list until it’s too late. NOt many artificial hearts have been transplanted yet. However, heart valves and pacemakers to help the heart pump blood better have been used for 40+ years and they are kind of ‘robotic’ and help replace lost function when hearts get worn out.

      The other examples is the pancreas which produces/balances insulin levels when we digest food. For those who are Diabetic, often their pancreas does not do it’s job properly so scientists, engineers and surgeons are workin up new ways to automatically monitor levels of insulin and then dispense it directly into the blood. If they can get this right they could (theoretically) replace the pancreas with a ‘robotic’ organ.

      There are loads of other examples of where bio-engineered parts are already transplanted into people for simpler bits of the body like joints, bone, skin, cartilage, etc. Organs are generally the trickiest though as they have many jobs and they do these in many different ways.

      We’ll get there in the end!

      Hi mee3megemel
      As Alex has already highlighted, we’ve had things that work short term for a few years – dialysis, heart bypass, and newer devices such as artificial hearts more recently.
      Engineering plays an important role in these devices – in the body, the cardiovascular system – your heart and vessels – is very good for transporting your blood without damaging any of the cells in the blood. When the blood is taken out of the body we have to be very careful that the tubes, pipes and pumps it runs through are safe and don’t cause too much damage to those cells (for example – a standard engineering pump could quite easily damage blood cells)
      As Alex said, perhaps the biggest areas for engineering development are longer term, smaller and more permanent versions of organs to replace these short term, temporary machines.
