Abstract: A robotic foot, to rest on a support surface and including: an attachment to an external object; a chain defining a contact area with the support surface; a first arm constrained to the chain at a first end of the chain and hinged to the attachment; a second arm constrained to the chain at a second end of the chain and hinged to the attachment; and elastic member adapted to reciprocally spread the arms keeping the chain taut and opposing a deformation of the chain when in contact with the irregular support surface.

Abstract: A robot including a limb including a robotic foot defining a contact area to a resting surface and an anchoring body of the robotic foot; a motor for moving the limb and a control unit for the motor; the robotic foot includes an attachment to the anchoring body; a contact member defining the contact area; a joint block of the contact member to the attachment including a first hinge between the contact member and the attachment, a second hinge between the contact member and contact and attachment; an additional hinge between attachment and joint block; at least one sensor for measuring a rotation; an additional sensor for measuring the additional rotation; and the control unit is configured to drive the motor according to the measurement of the rotations.

Abstract: A traction module for a robot system and a robot system using the traction module having, an outer frame and a rotating frame rotatably mounted within the outer frame. A drive system is operatively coupled to the rotating frame and configured to drive a traction drive component to propel the robot. An actuator is operatively connected to the rotating frame to controllably rotate the rotating frame. During a first portion of a rotating movement of the rotating frame, the drive system moves between a flat mode position relative to the outer frame and a clearance mode position in which the drive system extends outwardly from the outer frame to a greater extent than in the first position. During a second portion of the rotating movement of the rotating frame, the drive system may be positioned in a desired orientation to propel the robot.

Abstract: This disclosure provides systems and methods for in situ gap inspection in a machine, such as a generator, an electric motor, or a turbomachine, with an end region. A robotic crawler is configured to navigate an annular gap of the machine. A visual inspection module is connected to the robotic crawler and includes an extension member for extending a camera into the end region to collect visual inspection data.

Abstract: This disclosure provides systems and methods for an actuated sensor module for in situ gap inspection robots. A mounting interface attaches to the sensor module to the robot system. A least one arm is operatively connected to the mounting interface and has a joint. A sensor head is operatively connected to the arm at the joint and an actuator operatively connected to the arm moves the sensor head around the second joint.

Abstract: This disclosure provides systems and components for an omnidirectional traction module for use in a robot, such as a crawler robot used in in situ gap inspection in a machine, such as a generator, an electric motor, or a turbomachine. The traction module may include an outer frame and a rotating frame rotatably mounted within the outer frame. At least one drive system may be mounted within the rotating frame. The at least one dive system may have a fixed orientation within the rotating frame. An actuator may be operatively connected to the rotating frame to controllably rotate the rotating frame to a desired orientation for robot travel.
