Generation X

Announcing the latest and greatest development in the design and manufacture of autonomous airboats; the new Generation X Autonomous Airboat. Faster, more durable, more maneuverable and more reliable than ever before, it is truly a marvel of modern robotics. 


The all new GenX Airboat
Thanks to the hard work of our engineers back in Pittsburgh, we have successfully redesigned the airboats to address many of the shortcomings we noticed while testing in the Philippines. In just one week after the final design was finished and a prototype was tested, five boats were fabricated and now eagerly await testing.

The new GenX has several great new features we know you will enjoy. First of all, the shroud has been completely redesigned to use a single thickness of extruded acrylic. This helps keep manufacturing costs down and material tolerances at a minimum. The base of the shroud now has additional bolts and a locking spacer ring to keep the bearings within from jamming beneath the top retaining ring.



Permanent Mesh
Furthermore, by popular demand, the mesh on the back of the shroud has become a permanent feature rather than a bolt-on lawsuit deterrent. Using a ring to retain the mesh yields a cleaner design and more sturdily secures the mesh to the shroud, resulting in 80% less finger injuries. Nylon standoffs now replace the custom acrylic spacers use to secure the motor a fixed distance from the shroud. These new components are a cheap piece of commercially available hardware that greatly increases airflow to the motor and decreases the number of components that need to be laser cut.

While the shape of the hull is reminiscent of previous models, don't let that deceive you. The new GenX hull is thinner, sleeker and lighter to provide the smoothest ride possible. At just 4" thick, the hull protrudes from the water significantly less than its predecessors, decreasing the effect wind has on boat motion. The bottom of the hulls has also been covered with a protective rubberized compound to increase durability, particularly during repeated visits to the dry dock for repairs.


Rubberized hull coating
All in all, the new GenX is a true achievement in autonomous airboat technology and a testament to what can be accomplished with an Android phone, an idea and a whole lot of undergrad slave labor.

Testing in Maryland, a statistical summary.

Days 2 & 3 of testing in Maryland continued without many hitches.

In fact, Day 3 went so well that three of our brightest opted to stay on for an additional day of testing... aptly named Day 4.

Below is a statistical summary of the four days of testing...

Throughout the testing:
  • We were at the pond for 41 hours.
  • The boats were in the water for 22 hours 14 minutes. They were deployed 77 times. 
  • The average deployment time was around 17 minutes. 
  • 18 feet of Subway, 2kg of Chinese and 3 large pizzas were consumed. 
  • The boats travelled approx. 26.23km.* 
  • Max temperature reached 108°F!
*this figure has been estimated because we can’t be bothered working it out..

Graphical data
  • Graph 1 - Number of deployments 
Boat 1 was used most (after the rescue raft of course)
  • Graph 2 - Average deployment time 
Average deployment time increased over the weekend as bugs were found and efficiency was increased.
  • Graph 3 - Data collection 
JoyRideMode made this possible. This graph has been added for humour and serves no other purpose.


Day 4 ended with a hurried pack-up as the Maryland’s fiercest rains rolled in. Unable to operate in the rain, we packed up and called it a day. (Yes, we are aware of the irony of having to pack up for rain when the boats are destined for monsoons in Manila. No, we don’t need you to point it out again.)
