    Abstract: Implementations are directed to, for each of one or more joints of a robot, generating dynamic joint torque saturation limits for the joint, such as an upper joint torque saturation value and a lower joint torque saturation value. Implementations are additionally or alternatively directed to utilizing the dynamic torque saturation limits for the joint in generating driving torques and/or to driving a motor (or other actuator) of the joint based on the driving torques. Various implementations can enable regulation of contact forces for a robot in situations where the robot lacks joint torque sensor(s) and/or force torque sensor(s) and/or in situations where such sensor(s) are present, but have failed or are malfunctioning.

    Abstract: Systems and methods related to providing configurations of robotic devices are provided. A computing device can receive a configuration request for a robotic device including environmental information and task information for tasks requested to be performed by the robotic device in an environment. The computing device can determine task-associated regions in the environment. A task-associated region for a given task can include a region of the environment that the robotic device is expected to reach while performing the given task. Based at least on the task-associated regions, the computing device can determine respective dimensions of components of the robotic device and an arrangement for assembling the components into the robotic device so that the robotic device is configured to perform at least one task in the environment. The computing device can provide a configuration that includes the respectively determined dimensions and the determined arrangement.

    Abstract: Example implementations may relate to a cloud service that stores a detection metric corresponding to a maintenance request for a particular component. In particular, the cloud may receive sensor data from various robotic systems each having the particular component. The cloud may then determine, based on the sensor data, performance data for the particular component over time at the various robotic systems. The cloud may also determine various maintenance events for the particular component. Based on the performance data, the cloud may determine that at least one maintenance event occurs at other metrics that are different from the detection metric. Responsively, the cloud may adjust the detection metric based on a difference between the detection metric and the other metrics. The cloud may then detect operation of a particular robotic system at the adjusted detection metric and may responsively request maintenance for the particular component at the particular robotic system.

    Abstract: An example variable transmission system is provided. As an example, a variable transmission system may include a frame, an output hub coupled to the frame, a first linear actuator coupled to the frame, and a second linear actuator coupled to the frame. The variable transmission system may also include a tension-bearing element positioned around the output hub. A first end of the tension-bearing element may be coupled to the first linear actuator, and a second end of the tension-bearing element may be coupled to the second linear actuator. The tension-bearing element may include a variable stiffness profile such that a transmission ratio of the output hub may be adjusted based on a position of the second linear actuator relative to the output hub.

    Abstract: Techniques are provided for achieving stable tracking and/or manipulation by robots of objects. In various implementations, it may be detected, based on force signal(s) from force sensor(s), that an end effector of the robot has made physical contact with an environmental object. Based on the force signal(s), end effector constraint(s) may be identified. These constraint(s) may include a position constraint associated with position control of the end effector and/or a grasp force constraint associated with grasp force control of the end effector. Error measure(s) may be determined based on a measured position/force of the end effector. The error measure(s) may include a position control and/or grasp control error. The measured position and/or force may be compared with the end effector constraint(s) to reduce an impact of the error measure(s) on operation of the robot.
