Something with my Robe and Wizard's Hat

Being the terribly social being that I am, I was invited to a party with several other real-life people in attendance. This party was for Halloween and, of course, obligatory fancy dress. My kind friends suggested that I (as I would be the eldest attendee of said party) should go as some sort of befuddled wizard.

The finished article, as functional as it is ever likely to be.

Very quickly, the answer was obviously Rincewind, of Discworld fame, but the engineer in me realised that there was an opportunity to include an awesome accessory to this costume: Rincewind's faithful travelling companion The Luggage.

With my most optimistic engineering hat on, I decided that it would be well within my capability and resources to create a working robotic Luggage in the 6 weeks that I had before the party.

I'm going to split the design (I use the term loosely) and construction of this robot into several posts as there was an awful lot of "learning" (read: mistakes) that went on along the way. Hopefully it will serve as a decent record of what I did in case anyone out there would like to create a Luggage of their very own, and an archive of all the "learning" that I was able to do along the way.

Just in case you're impatient, here's the TL;DR synopsis:

  • "Design" is something that should come before "Build".
  • Mechanical losses will be more significant than you think.
  • If you know how to calculate something, calculate it, don't just ignore it.

  1. Regardless of how the mechanics turned out, it does look very cool! The feet have a certain charming piglet-like quality.
    I recognise the learning point in the TL;DR about the importance of design and planning. Separating design and construction always seems so inefficient at the time - the fastest way to completion is to start building as soon as possible, right?

    • I think you've hit the nail on the head there. The excitement of getting hold of a tool and making a thing can often be too much to bear (especially for home projects). Even on exceptionally simple projects I'd argue that one should still design first, it'll take such a short period of time and it's so beneficial.
