In our quest towards highly dexterous magnetic tentacle robots to reach deeper inside the human body and perform surgery, we realised that extremely soft continuum magnetic manipulators experience relevant twisting when interacting with controlling external magnetic fields and field gradients. So, if we want to precisely control their shape and avoid twisting, we need to add mechanical reinforcements along their length.

This is explained in detail in our latest publication supported by the ERC Consolidator Grant NoLiMiTs available open access at
