    Robobot Interface

    Unfortunately I didn’t catch the screenshot in time to catch Bruce dancing a jig in front of the robot, but I can assure you that that is exactly what he was doing.

    In case you’re wondering why I’m victorious, it’s because this morning I successfully got two different visualizers (in this case, Small Grey Image and Range Data) to display in two different viewports, complete with transparency layering. I’ve been working on getting this right for over a week.

    Once I got both visualizers working, I could get very good frame rates from both of them individually, but if I tried to display them together, I got a major slow down, particularly from the camera image. I thought that the problem had something to do with SDL’s surface blitting functions, but the problem was actually much lower level, in our message passing CMU IPC modules.

    I had Fritz turn down the rate at which the nav module broadcasts range sensor data, while at the same time lowering the rate at which my interface requests new camera image. As it turns out, the range data messages were basically overwhelming the message queue, such that if any camera data came in, it wasn’t handled before getting clobbered by newer range data.

    Right now, I’m added the color video mode visualizers, and then I have to figure out a good way to indicate the current camera orientation. In particular, I need to alert the user if they’re driving forward with the camera pointed to one side.

    It does get frustrating at times, but when I get stuff like this working, it’s a really awesome feeling. Fritz felt the same way when his robot monitor module RoboMon ran for 10 straight days without crashing. RoboMon also makes my life a lot easier, because now you just need to start up the interface with its config file. Last summer, we had to have several terminals open to the robot, to start up CMU IPC central, and the various modules (smmd, scmd, and svm). We’re in good shape, I think.

  • The Muppets Meet Murderbot

    For the last year and a half or so Andrle and I have been having a ton of fun as part of an online book club put together by my friend Tanya. Unlike most book clubs where you all read the same thing, we all just share things we love that we’ve been reading.

    One recommendation that kept coming up was The Murderbot Diaries by Martha Wells, and I’m glad we finally ran with it and started reading them. We’ve been bingeing the last few weeks and they’re really, really great. Highly recommend (even though I’m only on Book 4.)

    Unsurprisingly another thing I’ve been reading about and thinking about a lot is the advent of Large Language Models, particularly as manifested by ChatGPT. My past work life as an NLP practitioner has me a mix of curious, envious, and highly suspicious of what these are and how they’re being used. In the short term I don’t mind using them as a toy that I can play with for the purpose of a joke, which is what this post is about.

    A recurring topic in this book club is how we might have the Muppets interpret a particular book, or how we might recast a movie with Muppets (but keep one human actor). This provides a lot of fun discussions, especially since I grew up regularly watching the classic Muppet movies on VHS recorded off of TV, and I really like musicals.

    That all brings me to some prompt iterating that I did to get ChatGPT to write the painfully cliché finale to a Muppet musical featuring Murderbot. (Apologies to both Henson and Wells.)

    Verse 1 (Murderbot):
    I used to be a killing machine,
    A rogue cyborg, feared and mean,
    But then I met the Muppets and Kermit,
    And learned what friendship truly meant.

    Verse 2 (Kermit):
    I'm just a simple frog, it's true,
    But I believe in friendship too,
    And when I met Murderbot, I knew,
    Together we could do something new.

    Chorus (All):
    We don't need to kill no more,
    Our friends are all we're fighting for,
    With Murderbot and Kermit side by side,
    We'll show the world what we stand for.

    Verse 3 (Murderbot):
    I never wanted to be a tool,
    But that's all humans see in me, it's cruel,
    I used to dream of breaking free,
    From their endless schemes and greed.

    Verse 4 (Kermit):
    It's true, I'm always happy-go-lucky,
    But I've been through some tough times that were quite yucky,
    But now with Murderbot and the gang,
    I know our friendship will never hang.

    Chorus (All):
    We don't need to kill no more,
    Our friends are all we're fighting for,
    With Murderbot and Kermit side by side,
    We'll show the world what we stand for.

    Bridge:
    The past is gone, the future bright,
    With friends like these, we'll win the fight,
    Our love and trust will guide us through,
    Together we'll see this journey through.

    Chorus (All):
    We don't need to kill no more,
    Our friends are all we're fighting for,
    With Murderbot and Kermit side by side,
    We'll show the world what we stand for.

    Outro:
    So let's raise our voices high,
    And let the world hear our battle cry,
    With Muppets and Murderbot side by side,
    We'll change the world and turn the tide.
    OpenAI. (2023, Mar. 16) [Iterative prompt conversation starting with “This Muppet movie is about a rogue cyborg traveling to different space stations and learning the power of friendship from the Muppets” and “I need some lyrics for the big finals. The music is big broadway style number about how the rogue cyborg doesn’t need to kill bad guys anymore because it has friends.” and then encouraging more dialogue between Kermit and Murderbot] https://chat.openai.com/

    Yes, I looked up recommendations on how to properly cite ChatGPT output.

    Overall the result was mildly amusing. I couldn’t get it to capture Murderbot’s signature style, presumably because while information about the novellas are in its model training, not enough text from the novellas are in there.

    I’m still not sure what useful things I could do with this kind of tool, but in the meantime, I can make it make silly songs.
