Abstract
A robot comprises an arm having at least one joint comprising a joint driving means, the joint driving means having a plurality of actuation lanes; and a fault detection and isolation (FDI) system adapted to detect a fault in any one of the actuation lanes. The fault detection and isolation system in some embodiments is operable to isolate the or each actuation lane exhibiting the fault, and/or the robot is provided with a local control system connected to the fault detection and isolation system, the control system being operable to control the operation of the joint and to maintain, at least partially, operation of the joint when a fault is detected.
Claims23
A robot comprising:
- an arm having at least one joint comprising a joint driving means, the joint driving means having a plurality of actuation lanes;
- and a fault detection and isolation (FDI) system adapted to detect a fault in any one of the actuation lanes.
A robot according to any one of the preceding claims, wherein the joint driving means may comprise a common output shaft, which is driven by the actuation lanes.
A robot according to any one of the preceding claims, wherein the joint driving means comprises from two to 20 actuation lanes.
A robot according to any one of the preceding claims, wherein each actuation lane comprises a discrete actuator, each actuator being one of an electromechanical, a hydraulic or a pneumatic actuator.
A robot comprising:
- an arm having a plurality of actuatable joints;
- a fault detection and isolation system adapted to detect a fault in any one of the actuatable joints and, preferably, to isolate the or each joint exhibiting the fault, and a global environmental control (GEC) system connected to the fault detection and isolation system, the GEC system being operable to control the operation of the arm and to maintain, at least partially, the operation of the arm after a fault has been detected and isolated.
A robot according to any preceding claim, wherein the FDI system is operable to compensate for a fault in one or more joints.
A robot according to any one of the preceding claims, wherein the robot is a manufacturing robot or a maintenance robot.
A maintenance robot having an arm comprising a plurality of joints, the arm having in-built redundancy.
A system comprising:
- at least one manufacturing robot comprising an arm having a plurality of actuatable joints, each joint having at least one actuation lane and a fault detection and isolation system adapted to detect a fault in any one of the actuatable joints and/or actuation lanes and, preferably, to isolate the or each joint or actuation lane exhibiting the fault;
- at least one maintenance robot comprising an arm having a plurality of actuatable joints;
- and a global environmental control (GEC) platform or system connected to the fault detection and isolation system and operable, when a fault is detected and isolated, to deploy the maintenance robot and, preferably, when the maintenance robot is subsequently in close proximity to the manufacturing robot, to synchronise the motion of the arm of the maintenance robot with that of the arm of the manufacturing robot.
A method of fixing a robot, the robot having an arm comprising a plurality of actuatable joints having one or more actuation lanes, the method comprising:
- detecting a fault in a component in one or more of the actuatable joints and/or actuation lanes;
- isolating the actuatable joint(s) and/or actuation lane(s) exhibiting the fault(s);
- deploying a maintenance robot having an arm comprising a plurality of actuatable joints and an end effector;
- bringing the maintenance robot into close proximity with the faulty robot;
- synchronising the movement of the arm of the maintenance robot with the arm of the faulty robot;
- operating the maintenance robot to remove the faulty component(s) whilst maintaining synchronisation with the movement of the arm of the maintenance robot;
- and
- operating the maintenance robot to replace the faulty component(s) whilst maintaining synchronisation with the movement of the arm of the maintenance robot.
A method of controlling a manufacturing robot or a system comprising a manufacturing robot, the manufacturing robot comprising an arm having a plurality of actuatable joints, each joint having at least one actuation lane and a fault detection and isolation system adapted to detect a fault in any one of the actuatable joints and/or actuation lanes and, preferably, to isolate the or each joint or actuation lane exhibiting the fault, the fault detection and isolation system being connected to a global environmental control (GEC) system, the method comprising:
- operating the robot through the GEC system;
- detecting a fault in a joint and/or an actuation lane;
- optionally, isolating the faulty joint and/or actuation lane;
- and
- if necessary, operating the GEC system to compensate for the faulty joint and/or actuation lane, thereby maintaining, at least partially, the operation of the robot and/or the system.
A manufacturing robot or a maintenance robot substantially as described herein with reference to the accompanying drawings.
A manufacturing system substantially as described herein with reference to the accompanying drawings.
A method of fixing a robot substantially as described herein.
