New ExpressionFlow Studio video series
As you know, here at VI Shots we love video. So I’m excited that one of our favorite blogs has started producing a new series of videos focusing on LabVIEW Object-Oriented programming. I’ve embedded the first video above.
Tomi’s done a great job on the graphics, and he cuts from wide to close up shots nicely. [...]
Goldfish following camera powered by LabVIEW
Well, this video could use some editing but here it is. A totally useless application demonstrating the vision capabilities of LabVIEW. Watch a camera mounted on an X-Y motion platform tracking the movements of a goldfish in a fish tank.
Free Spore creature creator
I just downloaded the free Spore creature creator. I created my first creature, took some photos of it and even uploaded a video to Youtube directly from the software. All of the above in just half an hour of playing with it. It’s pretty slick.
I gotta hand it to the creators for coming up with [...]
Mars rover demo exhibit powered by LabVIEW
Describes the Mars Rover Exhibit Project made by students in the EPICS program at Purdue University and powered by LabVIEW.
Styrobots help Robotgrrl fund her school tuition
I always do what Google tells me to do. A few weeks ago my Google reader suggested that I should follow the robotgrrl blog RSS feed. So I did. This blog is about robotics from a Montreal, Canada High School girls point of view. Erin loves robots. So much so that she applied to the [...]
Slashbot Update – It’s finished!
We were the first to blog about Slashbot back in March. Now, Slashbot is Internet famous after it was featured on Engadget. It now has 177K+ hits on Youtube. A record for any video featuring LabVIEW or NI technology. I like the fact that it uses solenoids to hit the guitar buttons. This means it [...]
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.
