Abstract: A robot in accordance with at least some embodiments of the present technology includes a torso having a superior portion, an inferior portion, and an intermediate portion therebetween. The robot further includes two legs connected to the torso via the inferior portion of the torso, two arms connected to the torso via the superior portion of the torso, and a protrusion also connected to the torso via the inferior portion of the torso and extending anteriorly from the torso. The robot is configured to move an object toward the torso at least partially via contact between the object and at least one of the arms. The robot is further configured to support a weight of the object at least partially via the protrusion while the robot ambulates via the legs.

Abstract: A method is disclosed for reducing impact forces to legged robots as a result of traversing a terrain. The method includes employing actuators and compliant elements to use the contact of a first portion of a foot assembly with a terrain during a step to reduce the vertical velocity of a subsequent portion of the foot assembly so that the vertical velocity of the subsequent portion as it touches the terrain is substantially zero relative to the terrain. Foot assemblies that employ these methods are also provided.

Abstract: A deployment assembly is mounted in a delivery vehicle and holds an autonomous robot that can be deployed to deliver or pick up packages. The assembly has a base and extendable members that move the robot from a retracted position inside the vehicle and an extended position outside the vehicle. The assembly also has securement features that hold the robot in during transport and can also recharge the robot if necessary.

Abstract: A legged robot has legs that have multiple links, one of which is a distal link. A foot assembly for interacting with the terrain is disposed on a distal end of the distal link. As a robot takes a step, a portion of the foot assembly that has lower effective inertia than the rest of the foot assembly touches down first and acts to reduce the vertical velocity of the rest of the foot assembly before it reaches the terrain through the use of an actuator located on the distal or intermediate link.

Abstract: People and packages are delivered to and picked up from delivery locations by autonomous vehicles that also carry autonomous robots. When a package needs to be picked up or delivered at a particular location, an autonomous robot is deployed from the delivery vehicle and takes the package to the doorstep or other predetermined location or picks up the package from that location and brings it back to the delivery vehicle. After this pickup or delivery, the autonomous robot stows itself back in the delivery vehicle.

Abstract: A robot in accordance with at least some embodiments of the present technology is configured for bimanual manipulation of objects. The robot includes a body and two arms individually defining an arm length and including an end effector, an end effector joint proximally adjacent to the end effector along a kinematic chain corresponding to the arm, and a gripper proximal to the end effector along the arm length. The end effector joint is configured to rotate the end effector relative to the gripper. The robot is configured to move at least a portion of a bottom surface of an object away from a support surface by applying force to the object via frictional interfaces between convex gripping surfaces of the grippers and side surfaces of the object. This creates a gap into which paddles of the end effectors can be inserted to support the object from below.
