Under Construction

Week 2

This week I spent playing with the Legos and attempting to figure out how gears actually work. I also downloaded and installed Microstation. This proved to be non-trivial because the license supplied with the package is out of date. Another one exists in the Bentley directory on though, for the astute web surfer. Read the file and follow the simple directions for installation.

That being said, I've also been trying to figure out Microstation. It is a very complex program with little documentation. I found a tutorial online that is only average and only works for 2-D drawings. Check [1] for information. Additionally, it is worth noting that the default file type (.dgn) is 2-D when you create a new project within Microstation. Be sure to change the file type to .dwg when creating a new document.

Perhaps we can start up a Microstation FAQ, for instance. Maybe I will add a link to a skeleton to the main page. Help for even the smallest task would be fantastic. I cannot even make a cube!!!

Week 3

The motors work! The handyboard turned out to be a huge pain. Not having an engineering background didn't seem to help. I followed the links provided by Joe Kopena in his emails and downloaded the Windows version of Interactive C. The QuickStart was straightforward to follow. Problems arose when I discovered a faulty telephone cord (which made it impossible to connect the serial converter chip with the handyboard). This was not trivial to discover, unfortunately. Then, I discovered a faulty motor port. That is, all of the other motor ports eventually worked with the same code.

After all this initial setup was complete, I finally have a working handyboard and some motors. If anyone has similar problems, I would be glad to assist.

In other news, I have narrowed my project down to two different ideas. I am interested in getting the tw-legged creature to work, but do not know how feasible it is. I hope to narrow this down by Tuesday. My idea for balancing the two-legged creature is to use the handyboard to shift the center of gravity on the being. I plan on attempting to build a mechanism that shifts the handyboard left and right depending on which leg is on the ground. This may be idiotic, but my non-engineering self can see it working. If that doesn't work, I am going to default to a four-legged beast since balancing such should be easy and setup should be as well.
