This ultrasonic drilling mechanism does not require high axial load |
The USDC operated from a FIDO rover robotic arm |
The USDC operated from the Sojourner platform (a duplicate of the rover that was on Mars Pathfinder) |
In Dec. 2005, a 1.76-m deep drilled borehole in ice was created by the Gopher at Lake Vida, Antarctica |
This
Website describes the ultrasonic/sonic drilling activity of the JPL's Advanced
Technology Group and its NDEAA lab. The objective of this research team is to
develop an ultrasonic/sonic driller/corer (USDC) to enable acquiring samples
from various planets or small bodies (e.g., asteroid and comets) using low
axial load and low power. The drill bit
not does require sharpening, it can be made to operate at cryogenic and high
temperatures, non-round cross section cores can be created and it can be used
to probe the ground as well as deliver in-situ sensing down the borehole.
Ultrasonic and sonic vibrations are responsible for the drilling action.
Piezoelectric stack actuator in the upper section excites ultrasonic vibrations
that are transformed into sonic hammering action. The drill bit is forced to go up and down but
it does not rotate. The impact of the
bit into the rock performs the drilling. The device is being developed in
cooperation with Cybersonics. Finite
element analytical modeling was developed to maximize the performance of the
drill and allow effective design of various configurations. The USDC was
demonstrated to operate from a Sojourner size rover as well as from the robotic
arm of the FIDO rover. Drill head were
made that weigh .4-kg (1-lb), require axial load at the level of 3-10N and operated
by as low as 3-W. So far the USDC was demonstrate
to drill 25-mm (1-inch) deep holes in granite from a 4-kg platform, 15-cm and
15-mm diameter in sandstone. Also, a Gopher version was developed and
demonstrated to drill up to 1.76-m deep in ice at Lake Vida, Antarctica.
The USDC was selected the NASA/JPL Technology
Spotlight for the month of April 2000. Further, USDC was selected by R&D
Magazine (in the Sept. 2000 issue, p. 135) as one of the 100 most
innovative instruments for the year 2000
