To be able to use shape memory alloy (SMA) as actuators for precision grippers a precise controller is needed. Due to physical constraints, the controller needs to be either sensorless or using only smalls sensors. This physical constraint imposes to find a solution to remove the thermal video camera and the laser displacement sensor currently used for the test bench and this composes a part of this project. Also, to attain the objective of having a precise controller removing the cables connecting the SMA to the controller is important as this connection creates important parasite movement. To do this the passage to induction heating is needed.
