"[citation needed] The gastrobot's energy intake may come in the form of carbohydrates, lipids etc., or may be a simpler source, such as alcohol.
[citation needed] Gastrobotics could allow users to deploy self-sustaining robots for extended times without human supervision.
Other robots must plug in to recharge, so they require constant access to an electrical outlet, which limits range.
The main goal of this new technology is to produce robots that can go on missions where human supervision is not feasible or desirable.
The electrons then move through the ion-exchange membrane to the cathode chamber, where they combine with protons and oxygen to form water.
