Over the past couple of years we’ve been working on a rather cool new class of robots called Soft Curved Reconfigurable Anisotropic Mechanism(s), or SCRAM, under this National Science Foundation EFRI project. For my latest paper, Electronically Reconfigurable Virtual Joints by Shape Memory Alloy-Induced Buckling of Curved Sheets, I spent a lot of time working with shape memory alloy (SMA) wire while developing a SCRAM device. Much of this time was spent trying to figure out exactly how to solder to SMA wire, specifically a nickel (Ni) – titanium (Ti) alloy called nitinol. My conclusion after all that time? Soldering to SMA wire is really hard!
