The rescue mission of nuclear plant is both complex and dangerous, there is an urgent need to enhance the dexterity of rescuing manipulator to realize the automatic tool replacement for executing different tasks. A compliant exchanger for rescuing manipulator in nuclear plant is manufactured. The exchanger adopts a new double universal joint docking method, which can realize the compliant docking...
Rotary-percussive Drill (RPD) has been widely employed in extraterrestrial exploration as a main drilling and sampling device. Percussive mechanism, as an inevitable part of RPD, is commonly utilized to exert percussion onto drill stem to improve drilling performance once hard rock is encountered. However, since driving resource provided by the probe is limited in lunar exploration, outputs of percussive...
The mole is an axially symmetric intrusion device, which can be treated as a carrier of different sensors that investigate the subsurface environment and properties of the material component. To some extent, the maximum penetration depth of a single stroke for hammer-driven mole is not only limited by the stroke energy but also the influence of the soil resistance which links to the shape of the front...
