Sci­en­tists have de­signed new trans­par­ent, gel­based ro­bots that can per­form a num­ber of fast, force­ful tasks, in­clud­ing kick­ing a ball un­der­wa­ter and grab­bing and re­leas­ing live fish. The ro­bots, that move when wa­ter is pumped in and out of them, are made en­tirely of hy­dro­gel — a tough, rub­bery, nearly trans­par­ent ma­te­rial com­posed mostly of wa­ter, ac­cord­ing to the team at Mas­sachusetts In­sti­tute of Tech­nol­ogy in the US.
