These are the instruction booklets for the Gundam kits I made.The one on the left became black and red.The one on the right became blue and red like Optimus Prime

These are some Chibi Gundam kits I have been building. They are about 3 inches tall. I get them at the Robot4Less store, which is one major intersection away from my house. I am not finished with the black one. The last one is a figurine which comes already finished.

Big Boe-Bot (BBB)
Big Boe-Bot (BBB)
22 Feb 2012
This weekend I made a large Boe-Bot base using Parallax CNC motors (#27971). I scaled the Boe-Bot up 2.4X in dimensions. The Boe-Bot wheel diameter is 2.5" and the CNC wheels are 6" dia.
http://www.parallax.com/tabid/768/ProductID/507/Default.aspx
Motors: 3/4" wood, 1/4-20 x 1" screws.
Caster Wheel: 1/4-20 T nut, 1/4-20 x 2.5" hanger bolt, 1.25" dowel

SolidWorks Chibi Robot Assembly
This is a model of the shoulder joint on a walking robot I am designing.
This is the first assembly of this robot I have made in SolidWorks. Previously it was in Inventor.

LED's controlled by Gameboy
16 December 2009
The hardware version of "Hello World". Finished final exams today so got some time to do some hacking...
The Gameboy advance controlling an LED via it's serial port, aka Link Cable. Thanks to

Gameboy Programming
Sat 3 October 2009
I'm going to use a Gameboy, PSP, Nintendo DS, or somesuch device that includes a display screen, as a remote control for my robots. You'll press buttons on the device, and the software on the device will read the buttons and send commands out to a Zigbee/XBee wireless module. There will be a matching XBee receiver on the robot. My idea is to use this to control Robo-One type walking robots, because they have so many modes/motions/etc. The screen will be used to make a menu to make it easier to select different motions and suchlike.
So... I'm learning to program the Gameboy.
Here is a screenshot of my first program. It moves a crosshairs around on the screen via the Gameboy DPad (directional) buttons. Pretty fun stuff for a fine Saturday morning (if you are a geek, of course).
I'm using the HAM development environment and the VisualBoyAdvance (VBA) emulator running unders Windows XP. I'm learning from this excellent free book: Programming the Nintendo Game Boy Advance, by Jonathan Harbour, www.jharbour.com.

Borders & Templates in Autodesk Inventor
18 June Thursday
Made border for use in Inventor drawings. So much harder than AutoCAD. Made it into a template you can select just like ANSI(mm).ipt or ANSI(inch).idw.

Jeronimo's Mad Science Robot
Bristling with menance, the balloon-popper mechanism stands by for action.
A robot you would not want to meet in a dark alley.
Mechanisms include worm-drive gearbox and turntable gear.
I did not make this, but I wish I had. Jeronimo Hernandez Conde is the mad scientist.

Heffalumps just rule...
Do's and Don'ts
Heffalumps just rule...
Do's and Don'ts
- Don't attempt to make things bigger than the vise. Multiple parts on multiple pieces of stock is a major pain.
- Must leave more than one diameter clearance -- you need 2 diameters or 1.5 diameters
- This means your raw stock is reduced in size by 2 * diameter of the endmill all the way around, in this case, you lose a quarter inch of the entire perimeter of the stock. (1/8" endmill)
- You cannot contour pointy things
- Do not draw radii that are smaller than the endmill
- The radius on all transitions has to end up being greater or equal to the diameter of the endmill
- Don't use a drawing program that exceeds the CAM program you have -- it doesn't understand polylines, splines, etc.
- It's quicker to get another piece of stock and use the manual mill to prepare it to size than it is to spend hours looking at the screen trying to get all the pieces to fit. Rotation is really not quick in CAD.
- It doesn't work well to draw it big and then scale it down, this is where I got into trouble with all the radius problems
- KEY -- To check if the part will be able to be countoured in the CAM program -- here's whatcha do -- you offset it the diameter of the tool. Radii that are too small will fail to offset.
- I think it would have been faster in the end to pick an endmill size, pick a stock size, and draw it freehand in the CAM program.
Just ain't feelin' this tab...
Monday 4 May 2009 4:00PM
... so I ripped it off.
Damn, this thing is strong like a TANK.
Tab was in the way. Couldn't get the batteries or PCB by it. Test-installation of angle brackets.
Things your CAD program didn't tell you... Also totally SUCK is that the 2x2 batteries DON'T FIT because they hit the 4-40 nuts from the motor mount screws. That extra 0.2 inches was supposed to let those batteries fit. So now the motor to move the sensor doesn't fit either, because I lost 1/2" or so to the batteries.

And here is the result.
Not bad.
Started Friday evening and finished late Sunday night/early Monday morning, including an all-nighter.

Bolted motors in and made wheels
Sunday May 3 2009
10:00PM - 2:00 AM
I drilled/filed the mounting holes for the motors and got the motors bolted in.
I then used the LEGO rims and tires and drilled the hubs to mate with the LEGO. BUT, it didn't work, because the nut sticks out too far. Solution would be to tap threads into the hub. BUT, I already drilled the hole too big, plus, I don't have an 8-32 tap.
And, I'm on a mission to GET THE WHEELS ON at all costs, SO, I made different wheels.
I made wheels out of wood using a hole saw.

Final Virtual Model of Robot

3 May 2009
Final configuration of robot. Spent hours trying to shave off 0.2 inches. Really would like robot to be 2.8 inches square (I mean, cube). Finally settled on 3.0 inches though I really hate to have to give up those 0.2 inches.

It was a lot of work to model those parts, and at one point I wanted to throw my computer through the window, but now it seems worth it. The fun part is dropping all the parts onto the screen and moving them around.

Drew up the robot body the way it will actually be made. Learned about corner flanges in Inventor. Wow, this is really cool.
