PLANETARY WHEEL TYPE OBSTACLE CROSSING ROBOT

A planetary wheel type obstacle crossing robot, including a frame, a front drive set, and a rear drive set, is provided. The front drive set and the rear drive set are respectively connected to a front end and a rear end of the frame. The front drive set includes a dual-drive steering wheel structure, which includes two drive wheels and two first drive devices. The first drive devices respectively output different rotational speeds to the drive wheels, so that the dual-drive steering wheel structure rotates. The rear drive set includes two planetary wheel sets, two second drive devices, and a planetary wheel set suspension structure. Each planetary wheel set is individually driven and includes a front wheel, a rear wheel, and an upper wheel. The wheels of each planetary wheel set cooperate to climb over an obstacle under an action of a driving torque output by the second drive device.

Energy Efficient Legged Mobile robot
20220395974 · 2022-12-15 ·

A mobile robot includes a non-inverted pendulum body hereafter referred to as NPB with at least one pivot axis and this pivot axis divides the NPB into two portions. One portion of the NPB contains the center of mass of the NPB that can have structures to carry external payloads. The second portion of the NPB can have one or more manipulator arm and vision units. On the pivot axis is disposed at least one leg rotatabily coupled to the NPB. The other end of the leg has a foot joint on which is disposed a drive wheel or a foot. With additional degrees of freedom for each leg the robot can move similar to humanoids, be able to carry and sustain heavy loads with minimal leg joint torques and/or manipulate heavy loads and forces with self-compensating mass of the NPB while using minimal leg joint torques.
