The invention discloses a single-motor underactuated Mars aircraft sampling device, relates to an aircraft sampling claw, and aims to solve the technical problem of sampling and returning of Mars aircrafts. The single-motor underactuated Mars aircraft sampling device comprises a connecting support, a grabbing assembly, a driving assembly and a rocker arm assembly, and the rear end of the rocker arm assembly is rotationally connected with the connecting support; the grabbing assembly is installed at the front end of the rocker arm assembly, the driving assembly is installed on the connecting support, and the driving assembly is connected with the grabbing assembly and drives the grabbing assembly to be unfolded and folded. According to the invention, the actions of swinging of the rocker arm, clamping of the clamping jaw and withdrawing of the rocker arm can be realized in a single-motor under-actuated mode, the number of driving motors is reduced, and the mass of the sampling device is reduced, so that the sampling capability of the aircraft can be effectively improved under the condition that the maximum takeoff mass of the aircraft is kept unchanged. The invention belongs to the technical field of sampling and returning of rotor type Mars aircrafts.
一种单电机欠驱动的火星飞行器采样装置,它涉及一种飞行器采样爪,本发明为了解决火星飞行器采样返回的技术难题,本发明包括连接支架、抓取组件、驱动组件和摇臂组件,摇臂组件的后端与连接支架转动连接,所述抓取组件安装在摇臂组件的前端,所述驱动组件安装在连接支架上,所述驱动组件与所述抓取组件连接,并驱动抓取组件展开与合拢。本发明能够在单电机欠驱动方式下实现摇臂下摆、夹爪夹紧和摇臂收回的动作,减少了驱动电机的数量,降低了采样装置的质量,因此,可在飞行器最大起飞质量保持不变的情况下,有效地提高飞行器的采样能力。本发明属于旋翼式火星飞行器采样返回技术领域。
