| Exploded view of Bing's lower leg design
(picture recycled from last week). The parts are shown
in the image above; below is how they will fit together.

Didn't do as much this week as I had wanted to,
and the things I did do didn't really turn out like I
wanted. This week was therefore a bit disappointing, but
the future is a clean slate! Here's the rundown:
- Worked a bit on the host program that will run on a PC
and receive data from Bing, displaying it in a
comprehensible form. Perhaps a screen shot next
week.
- Got Bing's secondary processor board, a nice little
Motorola 68332 board called the MiniRoboMind, made
by Mark Castelluccio. It will be mostly devoted to
audio and video capture and will do the processing of
sound and images as well. Except for its lack of
documentation, it seems to be a pretty decent board for
somebody building a robot. Its connection pins are
certainly laid out better than the MPC555 board.
Unfortunately, I managed almost immediately to corrupt the
monitor program stored in the flash while playing with the
clock speed, so now I have to wait for a cable I can use
to reprogram the flash. Ugh.
- The MPC555 board is hereby named Fred, and the
68332 board is hereby named Barney.
- Built almost all of the parts for Bing's lower
legs. This week I'll be assembling them and working
on the design of the upper legs.
- Finally got around to hooking up the RC helicopter piezo
gyro that I want to use to sense rotation.
Unfortunately, it turns out that the silly thing puts out
pulses that are only 2.4 volts so the TPU function I
wanted to use to read their widths doesn't see the input
properly. So I have to build a little amplifier
which won't be too hard bit it is irritating.
That's about it. |
