LabVIEW powers MOT-V and Unicycle


 

Mike Kleinigger is currently a sophomore at RPI (Rensselaer Polytechnic Institute) pursuing a dual degree in Mechanical and Electrical Engineering. In this video He discusses the MOT-V (Medium Object Transport Vehicle) at NIWeek 2007. Unlike the Segway style vehicle, the MOT-V always tries to keep it’s position vertical as oppose to moving forward.We were surprised to see a unicyle which also uses a control system for stabilization.

    Correction: Commands are NOT sent via a bluetooth cellphone.

    Balancing is accomplished by the accelerometer and rate gyro, thus the further you lean in one direction or another, the faster you move in that direction in order to maintain stability. I’m not sure where this information came from, except that Dave was using his cell phone while riding the unicycle. It’s certainly possible to configure the system this way, but that’s not how it operates here.

    Thanks for the correction Mike. The statement about the bluetooth was removed. I assume then that if you lean forward too quickly it’s possible to tip over?

    Quite possible – in fact I’ve done it myself! To prevent such an unfortunate incident, it is possible to program the cRIO to sense when you’re leaning too far and compensate by further increasing the motor speed. In other words, if you lean too far forward, the device will quickly accelerate to get beneath you and halt your forward acceleration. This is one of many safety features on the commercial Segway. Also, with a more powerful hub motor (and more powerful driver circuitry), your maximum angle, and thus your maximum forward velocity can be increased.
