Introduction: Rising Box
How to build a box that will climb up structures.
This instructable was created in fulfillment of the project requirement of the Makecourse at the University of South Florida (www.makecourse.com)
Step 1: Materials Needed
- 3D software
- Access to a 3D-Printer
- Arduino micro-controller
- Bread board
- LCD display
- LED & subsequent 220 ohm resistor
- Stepper motor
- Wood planks
- Wood screws
- Impact driver
- Free floating grooved bearings
- Fishing line(or thin rope)
- Rubber band
- 2-Weights(each about 222g)
Step 2: Building the Box
Using Solidworks or Auto CAD software create the box and the wheel that will move the box up the support. The box should have flanges on the ends so it can be held up by the counter weights; along with cut outs for the LCD screen and LED to fit into. The model I used can be found below. These parts will then need to be converted into .stl files so that they can be printed on a 3D printer (Maker-bot preferably).
Step 3: Arduino Code
Here is the code with comments describing what each part of the code controls along with the Fritzing diagram, showing how each component is wired to the Arduino. (The function sketch must be added into the Make sketch in order for the stepper motor to work correctly)
Step 4: Final Construction
To create the support structure I used 2-6" x 24" and 1-4" x 24" planks of wood. It's held together by screws through the top and bottom along with corner braces at the bottom for additional strength. Also add the bearings at the top so the thin rope can move freely as the box moves up and down.
To complete the project Pack the electronic components into the box using glue or double sided tape to hold them in place. Add the rubber band onto the drive wheel so it has enough traction to climb the structure. (Optional: a top can be made by cutting out a box sized piece of acrylic or wood and screwing it in to the posts in the box). Then take both counter weights and string them so that they can run over the bearings and then to the box's flanges. Finally plug in an external power source and watch as as the box rises up and down the structure.
We have a be nice policy.
