BLIND FLIGHT WITH BOB
THE PROBLEM
THE LAST METER COSTS THE MOST.
01
OPEN TRENCHES, FOR WEEKS
Conventional installation means torn-up streets, bloecked sidewalks, and angry residents. Restoration costs explode.
02
EARTH ROCKETS FLY BLIND
Classic earth rockets have no telemetry. They launch and you hope they arrive. No tracking, no corrections, no knowledge of where the bore actually runs.
03
SKILLED WORKER SHORTAGE SLOWS EVERYTHING
Conventional drilling requires 2–3 specialists per machine. They're increasingly hard to find. Our technology needs one operator for two machines simultaneously – with no years of training required.
WE DRILL.
WITH INTELLIGENCE.
Stern Technic develops an integrated system of AI planning and autonomous drilling technology. WENDY plans. BOB and BUDDEL execute. No trench. No blind flight. Full control over the entire drilling process.
THE SYSTEM
ONE BRAIN.
TWO MACHINES.
WENDY Control is the central nervous system. It plans the drill path, monitors in real-time, and controls both machines — simultaneously, in different directions, from a single workstation.
AUTONOMUS - ELECTRIC
BOB
AUTONOMOUS DRILLING ROBOT
NO MORE BLIND FLIGHT
BOB is tracked via the IMU directly from the start pit in position and direction. You always know where it is — unlike any earth rocket.
NO MORE BLIND FLIGHT
Maintains position independently, stops automatically at drill end. Start and end pit required — but with complete position monitoring.
NO MORE BLIND FLIGHT
No compressor, no hydraulic unit. Purely electric drive - quiet, emission-free, deployable in sensitive areas.
SEMI-AUTOMATIC - PNEUMATIC
BUDDEL
COMPACT UNIVERSAL DRIVE
SECURED ADVANCE
Unlike the earth rocket: BUDDEL offers a controlled, secured advance. No uncontrolled shot, but reproducible results.
2–3X FASTER
Significantly faster than an earth rocket in 50mm dimension. Semi-automatic: drive pipes are manually screwed in, the advance itself runs automatically.
230V OUTLET
Operates with a small piston compressor at 230V. No heavy equipment needed. Universal drive, expandable: booster, high-pressure water flush — with or without suction, depending on soil.
SIMULTANEOUS OPERATION
BOB and BUDDEL can be connected to a single WENDY station simultaneously and work in different directions. Two bores in parallel - one operator.
COMPARISON
WHY NOT USE AN EARTH ROCKET?
Parameter | BOB | BUDDEL | Earth Rocket |
|---|---|---|---|
DRILL PLANNING | WENDY | WENDY | Manual/ None/ Third-Party App |
EXPANDABILITY | Self-Contained | Booster, Flush, Suction | Limited |
POWER SUPPLY | 230V WENDY CONTROL | 230V WENDY CONTROL, small Compressor | Large Compressor |
SPEED (D50mm) | Slower, but autonomous | 2-3x Faster | 20m/h |
DRIVE CONTROL | Fully Autonmous | Secured Advance | Uncontrolled |
POSITION TRACKING | IMU Real-Time | Via WENDY | None ( Blind Flight) |
PROCESS
FROM CALL TO CONNECTION.
01
CONSULTATION
We analyze your project and the conditions. Together we decide: BOB, BUDDEL, or both — and whether purchase, rental, or full service fits best.
02
WENDY PLANS
WENDY calculates the optimal drill path. Start and end points, soil conditions, obstacles — everything is planned and simulated in advance.
03
DRILLING
BOB drills autonomously with IMU tracking. Or BUDDEL works semi-automatically — manually screw in pipes, advance runs automatically. In both cases: trenchless, in hours.
04
CONNECTION
Line installed, surface intact. Fiber optic, power cable for the wallbox, or utility line — your connection is operational.
COLLABORATION
YOUR PROJECT.
YOUR MODEL.
Depending on project size and requirements, we offer different ways of collaboration.
PURCHASE
BOB and BUDDEL as your own equipment. Including WENDY license, training, and support. For companies with continuous drilling needs.
IDEAL FROM 50+ DRILLS/YEAR
RENTAL
Flexible rental per project or time period. Including WENDY Control and technical support. No capital commitment, full flexibility.
IDEAL FOR PILOT PROJECTS
