Design Project


If you don’t know what an Arduino is, begin by becoming familiar with the Arduino.


Design, build and demonstrate a finished Arduino-based project.  I suggest you do a two-servo rover.  You may do a Raspberry Pi or other project as approved by your instructor.


Read this carefully, If you do not follow these directions, you will have to re-submit with a letter grade deduction. Double check each of these before you turn in your file.

In a SINGLE FILE,  AUTOCAD 2005 or 2004 DWG format, the following:


  • Working drawings for one of the parts you want to have made for you.
    • Must be properly dimensioned.
    • May be single view drawings with note to thickness.
  • NESTED Laser outlines of the parts to be laser cut.Laser outlines must be NESTED properly on an 8 x 10 and/or on an 8 x 5 rectangle.
    • Outline to be cut on a layer named “LASER”
    • Properly offset to allow a .010 kerf.
    • Turn in by email
    • Email subject line must read “TECH 1521 – PHASE I”

    NOTE: CHANGES to be made next time I teach this class:

  • Max additional material usage is a single sheet of 12 x 18 (pre-cut)
  • File name must be yourlastname_Phase1.dwg
  • Save as *.dxf if you are using an educational version.
  • Letter grade deduction for line on top of lines.


  • Assembled & working project
    • Email a linkto your project web page.  It must be on a public page (such as
      • Email subject line must read “TECH 1521 – PHASE II”
      • Your webpage must have photos and description
      • Video is a good addition
      • Be aware that the acrylic will have a protective layer on it that should be removed before you assemble your project.
    • NOTE: In your email, you can request that I not publish your link.

Ungraded student projects from Fall 2012

Two-Servo Rover

Here are the parts you will need if you are designing a rover. Mine was about $60. Here is a similar bot.

Jameco is a good source for many of these parts.

  1. Arduino Uno R3 Board (Amazon, Radio Shack, etc.  Comment if you find a good deal).
  2. Two (2) Parallax S35 Continuous Rotation Servos(PN 900-00008) or other CR servos.
    • (I got both for $28.57 delivered)
  3. A 4x AA Battery holder (example)
  4. A 9V Battery clip (example)
  5. A SPST Toggle Switch (example)
  6. Some 22 ga. Hookup Wire (don’t buy, you only need a few inches).
  7. Some Machine Screws (based on your design)  Here is what I used:
    • A box (qty: 100)  #6-32 Machine screws (Hardware store)
    • A box (qty: 100) of #6-32 Nylon Lock Nuts

I will give you the following:

  1. Four M3 x 0.5 Screws & Nuts. For mounting the Arduino.
  2. One and a half sheets of Acrylic 8.0 x 10.0 x 0.080 inches.
  3. AutoCAD Drawings of some of the common parts.
    1. Arduino_Uno R3 DWG
    2. RoverParts DWG
  4. A sample program to get your rover moving
    1. SimpleServoBot.txt

If you want more acrylic, you can purchase it yourself.  It must say Acrylic on it and can be up to .250 thick (you can also use EVA “craft” foam from Hobby Lobby).

NOTE: The maximum dimensions for any acrylic you bring must be less than 12 x 18.  I will not cut acrylic for you.  Plan accordingly.

Hint: You will want to take your project further, make it easy to access the Arduino terminals.  Consider attaching a breadboard to your robot.
