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.
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.
