Abstract

An obstacle avoidance motion carrier includes a motion base and a rotation module. The motion base is configured to autonomously move, turn and rotate. The rotation module is disposed on the motion base and includes a rotation axis actuator and a rotation carrier plate. The rotation axis actuator is fixed on the motion base. The rotation carrier plate is disposed on the rotation axis actuator and connected to the rotation axis actuator, in which the rotation axis actuator is configured to rotate to drive the rotation carrier plate to rotate relative to the motion base. The obstacle avoidance motion carrier may further include a first horizontal movement module and/or a second horizontal movement module to achieve obstacle avoidance performance of the obstacle avoidance motion carrier in horizontal direction(s).
