Soft robotics

Interesting topic called Soft robotics. Shape changing, regenerating

Instead of a spring you can use a fishing line (Science, 21 Feb 2014, Vol 343, Issue 6173, pp. 868-872). Just twist the fishing line and will swirl into thin spring. If you apply heat it will contract. If you wind up a copper whire around the fishing line first then it can dissipate heat when electricity is applied to the wire.
