Abstract: Robotic systems can be capable of collision detection and avoidance. A robotic medical system can include a robotic arm, an input device configured to receive one or more user inputs for controlling the robotic arm, and a display configured to provide information related to the robotic medical system. The display can include a first icon that is representative of the robotic arm and includes at least a first state and a second state. The robotic medical system can be configured to control movement of the robotic arm based on the user inputs received at the input device in real time, determine a distance between the robotic arm and a component, and provide information to the user about potential, near, and/or actual collisions between the arm and the component.

Abstract: In examples, a robotic medical system comprises a link of a robotic arm and a processor configured to control movement of the link based on a received input; determine a distance between the link and another object during the movement; and, responsive to the distance being within a threshold, adjust the movement of the link to avoid a collision between the link and the another object.

Abstract: Systems and methods for collision detection and avoidance are provided. In one aspect, a robotic medical system including a first set of links, a second set of links, a console configured to receive input commanding motion of the first set of links and the second set of links, a processor, and at least one computer-readable memory in communication with the processor. The processor is configured to access the model of the first set of links and the second set of links, control movement of the first set of links and the second set of links based on the input received by the console, determine a distance between the first set of links and the second set of links based on the model, and prevent a collision between the first set of links and the second set of links based on the determined distance.

Abstract: Certain aspects relate to systems and techniques for a patient platform system that includes a table and one or more kinematic chains that are coupled to the table. The table includes a rigid base and a table top that is movable relative to the rigid base. One or more processors initiate first movement of the table top relative to the rigid base in accordance with a user request, and move the one or more kinematic chains relative to the rigid base in coordination with the first movement of the table top such that one or more preset conditions are maintained during the first movement of the table top.

Abstract: Certain aspects relate to systems and techniques for optimizing the configuration of a robotic system by moving the links of the system in a null space to minimize a cost function. The null space being defined by the desired set of end effector pose. The cost function may be evaluated by computing the distance of the links from various avoidance zones. The avoidance zones are associated with collisions and joint limit conditions. The systems and techniques may specifically relate to a system wherein the optimization includes movement of an arm support. The system may be employed pre-operatively or intraoperatively to minimize collisions and joint limit event during the course of a procedure. The system may be used at intervals. The system may be used each time the end effectors are commanded into a new pose.
