“…Sampling volume 5cm 3 Deploying velocity 3.5mm/s In addition, the corresponding signal acquisition and control system was developed, the experimental device is shown in Fig.14. The accelerometer which is fixed on the sampling head is used to measure the vibration amplitude of the sampling head.…”

“…The connecters used in multi-stems typed arms are generally joints, rack-pinion or spiral tube–screw. The structure of the lunar regolith sampler of “Surveyor 5” (1967) is a parallel connecting rods structure which can expand or retract by controlling one of its ends [3] . The Instrument Deployment Device (IDD) of NASA's Mars Exploration Rovers (2003) and the JPL's Rover are tandem joint type structure arms which have more freedom, although they possess too much weight and contraction volume [4,5] .…”

For the task of shallow lunar regolith sampling, we have designed a novel Measuring Tapelike Sampling Arm and Drill (MTS) which is a kind of flexible robot. The advantages of the sampling arm are that it has a small shrink volume, long working distance, light weight, low power consumption and good adaptivity, which is driven by one motor only. Furthermore, it has a large reverse torque with a short force arm, so the pushing force is large enough for the end-effector to penetrate into the lunar regolith. The sampling head which includes two opposite rotating parts has no-reaction screw force. The vibrator located in the sampling head can vibrate at frequencies ranging from 1 to 42Hz and can result in resonance of the sampling head. Therefore, it can improve the efficiency of thrusting, sampling and casting throw. We have carried out theoretical analysis, simulations and experimental studies and it is has been proved that the sampler can sample quantitatively at a of depth of 10 cm in simulated lunar regolith (model CAS-1), cement and sand.

“…Obtained samples were analyzed on the surface of the moon applying instruments. The sampling mechanism of Surveyor is made up of telescopic boom and a shovel with a controllable gate in the front of it, which is mainly used in the research on mechanical properties of lunar soil [6][7]. The sampling mechanism of Surveyor is shown in Fig.…”

Lunar soil sampling is an important task for lunar probe. It is the premise of the analysis of lunar soil and the study of lunar environment and evolutional history. Lunar soil sampling techniques have different classifications according to different standards. In view of goals of China's lunar exploration sampling project, a design of digging-typed lunar soil sampling device based on the mechanical arm is proposed in this paper. Mechanical characteristics of digging sampling process are analyzed in EDEM as well. Analysis results based on discrete element method show the compressive stress distribution of lunar soil particles during the digging process, vertical force and horizontal force of the sampling device during the digging process and the weight of samples in one sampling action. These simulation results prove the feasibility of the sampling device and lay the foundation for China's manned lunar exploration in the future. 978-1-4673-9675-2/15/$31.00 © 2015 IEEE
