VI Shots

Out of the many submissions to the NIWeek 2008 demo contest, this year we have yet another console game meets LabVIEW. Texas A&M students: Dave Buckner, Mitchell Jefferis, Vinny LaPenna, and Michael Voth are working on Slashbot.

From their blog:

To put it simply, we are designing a robot that is capable of autonomously playing a video game, the wildly popular Guitar Hero series. In the game a player attempts to simulate playing songs as color-coded buttons corresponding to notes scroll on the screen. A sensing and computation system will analyze the NTSC video signal as it is output from a PlayStation2 gaming system. The buttons a player is asked to press will be detected and an appropriate control signal will be sent to the robot. The robot will consist of six solenoid actuators, one for each colored button and one for the “strum” bar.

Someone at NI just put up a slew of funny LabVIEW related videos on Youtube. I assume these are interns. Check them out below.

PS: Can you spot the Dr. T cameo?

Anybots just released a new video of the next version of Dexter. Dexter is a biped teleoperated robot created by the Mountain View, CA based company.

Dexter’s walking is performed autonomously and is a demonstration of the type of hybrid robot that Anybots is working on. It will mainly be teleoperated but certain tasks will be automated such as walking.

Here’s a VI Shots video of the Anybots team during last years Robodevelopment conference:

NXT-G Online is software that allows you to program a virtual Lego Mindstorms NXT. Are you a school that doesn’t have enough cash for an NXT hardware set. No fear, this virtual software actually lets you program in NXT-G and download to a virtual NXT brain. Then you can execute the code and see it in virtual action.

To help better understand what is going on in the video, here is the sequence of chronologically events:

• A challenge was selected – a video that came up introduced the challenge.
• The simulated NXT-G programming environment was opened
• Wrote some code (4 motor blocks were dragged onto the palette, and each was set at a different power level).
• Downloaded the NXT-G program to the virtual NXT robot, which automatically opened the virtual environment.
• The robot was moved to where we wanted it to start.
• The virtual NXT brick was opened and we ran the program that was just created. The robot moved accordingly.

Note that the release version of NXT-G Online also has the ability select different sensors and motors for the virtual robot after which you can go back and change your code to make use of your modifications.
