Hand controller apparatus including ergonomic features for a robotic surgery system

A hand controller apparatus for controlling one or more tools in a robotic surgery system, the apparatus comprising:

• a body including a proximal portion and a distal portion extending to a distally located interface end configured to be coupled to an input apparatus configured to control a surgical tool, the proximal portion configured to support at least a portion of a palm of a user's hand thereon;
• a lever having a tail end pivotally coupled to a side of the body and extending distally to a paddle end of the lever;
• an input control interface on an upper surface of the body and configured to receive an input from one or more fingers of the user's hand;
• and
• a lateral movement detector configured to magnetically or inductively detect a lateral movement of the lever, wherein detection of the lateral movement causes the input apparatus to control movement of the surgical tool based on the detected lateral movement of the lever, wherein the lateral movement detector comprises a magnetic angular sensor configured to detect an angle formed between the lever and the side of the body or an inductive sensor configured to detect a non-linear movement of a metallic portion disposed in or integrally formed with the lever.
