Add
  • Asus Laptop (Driver station) power supply/charger. Can't find it right now and we  seem to misplace it often.
  • Lexan of different thickness. 1/16 and 1/8 likely most useful.
  • Light for vision illumination. The rings we have are pretty beat up. Should try to fix them too.

Arcadia / Getting the trackball to work with MAME
« Last post by Louis L on November 19, 2017, 04:24:57 PM »
Documenting this here so that we don't have to re-learn it.

The trackball console acts as a mouse via the Ultimarc OptiPac USB converter. This converter drives the opto sensor on the Happ trackball and converts trackball movements into a USB mouse.

When connected to the MAME laptop, the trackball mouse works on the desktop but not in MAME by default. To change that,
  • Run MAME without a game argument. This puts you into MAME screen where you can select games to execute.
  • Hit <tab> to selet the Configure Options menu.
  • Use arrow keys in the popup "Settings" menu to select "Device Mapping". Hit <enter>.
  • Under "Trackball Device Assignment", set it to "mouse".
That's it.

Today XAMPP got installed and WordPress got downloaded. Once I install wordpress and mess with those settings it will be time to put in the content. We should also decide on the input/interface method soon.

I played Mario and Mario 2 on the NES and recorded the sound directly from the console into WAV files.

Here's the mapping for the 2 joysticks

Left  Joystick
  Up:  'R'
  Down: 'F'
  Left: 'D'
  Right: 'G'

Right Joystick
  Up: up arrow key
  Down: down arrow key
  Left: left arrow key
  right: right arrow key

The 2 small square buttons on the left side of the panel. These are normally the 1-coin and 2-coin sensors
  Left red button: '5'
  Right red button: '6'

The 1 and 2 player start buttons (white with human stick figure)
  Left 1 player button: '1'
  Right 2 player button: '2'

I'm NOT positive about the rest of these - need further testing to confirm.
Buttons from left to right.
  On left, <color?> button: 'X'
  In middle, <color?> button: left shift key
  On right, red button: 'Z'
  On right, green button: space
  On right, left orange button: left alt key
  On right, right orange button: left ctrl key

When you get a chance, do you mind telling me where each button maps to?

Bay State Brawl / Re: Post-BSB - What worked, what didn't, what to do better next year!
« Last post by Louis L on November 07, 2017, 10:39:06 PM »
II thought overall bsb was fun and I really enjoyed being on the drive team. However I think after the 2 matches I had and mmy shift was done for volunteering it was kind of boring.  I think next year there should be something to do when you are done with everything you have to do.

Any ideas what can be done? It's hard because we have a large number of students. Most teams probably had just one drive team so they kept busy but we had 4.

There's also the reality that when we go to a real competition, those not actively working in some way will get bored. So we encourage everyone to be responsible for doing something.

The Good
  • It was energetic.
  • We got a good turn-out.
  • We built a sense of collaboration and friendly competition with the teams in our area.
  • The community knows about us now!
  • R5-D4 came!
  • The MC's were hype beasts!

The Bad

  • The competition itself got a bit repetitive.
  • The sound system mishap during the national anthem
  • Spectators who weren't robotics team members had difficulty understand what the robots were supposed to be doing.

The Ugly

  • The flooring was pretty uneven.
  • Our team spirit fizzled out a little towards the middle of the competition.

Overall, it was a great time. Let's do it again next year, and make it even better!
