摘要: Example embodiments relate to a robotic device with at least two legs. Each leg includes a foot including a first sole and a second sole perpendicular to the first sole. Each leg additionally includes an ankle joint configured to rotate the foot from a first position in which the first sole is contacting a ground surface to a second position in which the second sole is contacting the ground surface. The robotic device includes a control system. When the foot of a given leg of the at least two legs is in the first position, the control system may determine to cause the foot of the given leg to switch from the first position to the second position, and may cause the ankle joint of the given leg to rotate the foot of the given leg from the first position to the second position.

摘要: The present application discloses an apparatus capable of walking and flight. This apparatus includes a central section supported by a plurality of limbs, wherein a distal end of each of the plurality of limbs defines a contact surface. These limbs are configured to generate a walking-type motion in which the contact surfaces of the limbs cooperate with an environmental surface in a manner sufficient to propel the central section relative the environmental surface. The apparatus further includes a motor operably coupled to at least one limb of the plurality of limbs, wherein the motor is drivingly coupled to a propeller, and wherein the motor and propeller are configured to propel the central section in flight.

摘要: A robot design system, and associated method, that is particularly well-suited for legged robots (e.g., monopods, bipeds, and quadrupeds). The system implements three stages or modules: (a) a motion optimization module; (b) a morphology optimization module; and (c) a link length optimization module. The motion optimization module outputs motion trajectories of the robot's center of mass (COM) and force effectors. The morphology optimization module uses as input the optimized motion trajectories and a library of modular robot components and outputs an optimized robot morphology, e.g., a parameterized mechanical design in which the number of links in each of the legs and other parameters are optimized. The link length optimization module takes this as input and outputs optimal link lengths for a particular task such that the design of a robot is more efficient. The system solves the problem of automatically designing legged robots for given locomotion tasks by numerical optimization.

摘要: Example methods and systems for planning a body position for a robotic device are described. An example method includes receiving a reference step path that defines predetermined step locations for end components of a robotic device. The method also includes receiving a set of constraints, receiving a predetermined height and pitch, and assigning a cost to each of a height of the body, a height acceleration of the body, and a pitch acceleration of the body. The method also includes determining a new height and a new pitch of the body that reduces the height acceleration and the pitch acceleration of the body when the end component moves along the reference step path. Further, the method includes instructing the robotic device to actuate the plurality of appendages to achieve the new height and the new pitch of the body when the end component moves along the reference step path.
