The Two Wheel Deal is a compact, two wheeled, self-balancing personal transportation device. It serves as an economical and practical alternative to most forms of short range transportation, including cars, bikes, and walking. Having only two wheels gives The Two Wheel Deal a small footprint for enhanced mobility over conventional means of transportation. Additional features such as high speed motors, emission free electric drive, and a zero turning radius make the Two Wheel Deal like walking, only better.
The Two Wheel Deal is complete! All PSSCs have been successfully demonstrated and there are very few bugs left.
After repairing a few electronic and mechanical issues, the control algorithm of The Two Wheel Deal was improved. It is now quite easy to ride.
The Two Wheel Deal can sucessfuly turn and balance itself as well as a passenger. Finishing touches will be added in the following weeks.
The PCBs have been fully populated and partially tested. Both motor controllers are working at low currents. High current testing will have to wait until we are able to apply a load to the motors.
We assembled The Two Wheel Deal's basic frame - including the motors, wheel hubs, wheels, and tires. A picture of the assembly (without the tires) is available on the Media page. The PCB for the motor controllers has been completely redone after some discussion during the design review. The new design is available on the Documents page. Initial software is up and running on the ATmega32, including the LCD screen, ATD converters, and the 16-bit PWM.
The Documents page has been revamped and the Links page updated. PDF versions of all files have been added so that they can be viewed by a larger (and less Microsoft friendly) audience.
Our steel frame was welded together and mounting holes were drilled to attach the motor. We also picked up our group laptop.
Our motors and batteries have arrived, and we've ordered wheels, a microcontroller, and an LCD screen.
Group 12 is now on the web! We've decided on our project and we are now searching for parts. Most of the parts are terribly expensive, providing us with our first challenge of finding an affordable solution. We are currently in need of a large number of high current MOSFETs, another angular rate sensor, an LCD screen, some proximity sensors, various voltage regulators, LEDs, capacitors and tons of other little parts.
