ESA: Wood Wasp Drill
(Ref: 11 NL 1D1D 3K76 )
The wood wasp and its capability to drill into wood has raised
much interest within the space community. Therefore, a device
imitating the wasp’s ovipositor drilling technique was invented by a
leading UK University, with promising advantages such as very
low power needs and increased drilling speed. The university is
interested in exploiting this discovery within suitable applications
such as mining where power limitation demands new approaches
to drilling, preferably using licensing agreements.
Description:
Drilling principle:
The dual reciprocating drilling is based on two interlocked drill bits
that can slide against each other. It begins with one drill bit moving
into the drilling target and getting engaged with the target. The
reaction force or resistance induced by the target to that drill bit
will help to push the other drill bit further into the target. A
repetition of this process will allow advancement of the drill into the
target material without any external axial force.
Prototypes and testbed:
The existing prototypes have employed a cam mechanism to realize the dual reciprocating
motion. A commercial on the shelf DC brush motor is used to drive the mechanism. Except the
drill bit, which is made of steel, the drill is made of aluminium. The testbed facility is set up to
allow automated operation and control of the drill including data acquisition and analysis. The
test results indicate that the wasp drill can be as much as 10 times lighter than its rotary
counterpart and drill several times faster than the percussive drill using the same power.
Innovations and advantages of the offer
Completely novel technique allowing for improved efficieny, drilling and low-cost engineering
design, compared to conventional approaches.
Nowa metoda do łatwego diagnozowania błędów manipultarów lub narzędzi
specjalnych.
New method to easily locate errors at manipulators or special tools.
(Ref: 11 DE 1380 3KET )
A German SME active in the field of PLC controlled automation engineering is looking for a
partner for further development of pneumatic cylinders having an LED visualization to indicate
error messages.
The new visualization enables a three-dimensional view of the error and errors at manipulators
or special tools in the production process can be identified and located more quickly. The SME
looks for a manufacturer of pneumatic cylinders interested in making this technology ready for
the market.
Description:
The new visualization method of errors occurring at manipulators or special tools is based on
a pneumatic cylinder or an electrically controlled cylinder that is equipped with LEDs. In case
of an error these LEDs light up and thus it can be easily located where the error has actually
occurred.
The error message is formed in a PLC and sent to the pneumatic cylinder.
The LEDs are integrated directly in the cylinder and addressed with 24V DC.
They must be visible from all sides of the manipulator in order to assure that they are not
covered by other components.
