Wall-Climbing Vehicle

In a world where aliens have invaded and destroyed New York City, the iron structures of the skyscrapers are all that is left. Humans have developed this vehicle to climb up the frames and escape from the aliens whose inner magnetism render the iron structures deadly. 

This vehicle uses magnetic treads to stick to magnetic metal surfaces. The vehicle is controlled by a remote control, which make the two motors drive the treads forwards. The 3-D printed treads are attached to a wooden frame, which holds the magnets in place. 

Flapping Car

Our final product is a car with wings that flap, wheels that can be controlled, and LED lights that change color based on the control of the wheels.

The Geared Vehicle is for a time in the future when quicksand covers 90% of the earth. This vehicle is able to elegantly traverse even the most dangerous quicksand pits using its innovative geared wheeled system. The vehicle is able to both go straight and backwards. And by bilaterally disengaging the gears, the vehicle is able to turn left and right. After the Great Sandstorm, human survival will depend on vehicles like this to allow us to continue to traverse great swaths of what is now a giant desert.

Cylindero

Seth Gillett and Saba Ghole

Our project, Cylindero, is a radio controlled vehicle with lights, and is capable of driving at fairly high speeds. Now completed, the interior electronic components of Cylindero are no longer visible. Cylindero is constructed of 3d printed plastic components, most of which were designed in the early stages by us. Our concept has changed since the beginning, for practicality and structural reasons, but it is very close to what we originally planned, and for that we are proud. We did, however, face design challengs which we were forced to overcome. For one, a base problem of Cylindero is its main design. For it to work, the motors must be the centerpiece, not the arduino or battery. The whole construct would have to be suspended from the motors, meaning both the cylinder wheels and the outer cylinder would need to be able to take a lot of strain from continous running. To solve this problem we chose sturdy motors, but in addition we replaced the motor axle with a sturdier mount (or hub) to connect to the cylinder wheels. Another problem we faced was spinning of the interior. If not properly secured, the interior of Cylindero would spin instead of the exterior (the same reason why a flying machine with one blade would not work). The motors needed leverage, something to push against. To solve this problem we suspended all the weight below the motors, however it does still remain a technical difficulty that is a product of its desgin. We will now demonstrate this vehicle's power in action...

OmniCar

Saba Ghole

The OmniCar exists in a future overpopulated world. It serves the function of allowing the driver to avoid other drivers and people with its agile maneuverability. The original idea for the OmniCar was to have three spherical drive wheels. We redesigned the OmniCar because we realized that getting the three powered wheels to be coordinated would be nearly impossible to accomplish in two weeks. We decided on one large wheel because the car would work just as well with one drive wheel and it would not require complex coordination. Along with the original three wheeled design, we were going to have an accelerometer in the palm of our hand and a knob to turn for throttle control. We changed this design slightly, and excluded the knob and instead just kept the accelerometer. The direction and speed are now controlled by tilting the glove that the electronics are attached to. We left the car uncovered to show the drive wheel and how it works.

The next thing that we would do is improve the drive wheel to increase the speed and to improve the stepper motor that we used to turn the gears to give it better functionality. One of our biggest challenges was that we spent a lot of our time designing parts that would later become unnecessary. Another big challenge that we faced was that the stepper motor did not turn the drive motor to the correct angle because it did not have enough torque to overcome the resistance of the gears.
