We will be using freely available tools like Google SketchUp to design and finally fabricate a chassis for a robot.

Step #1: Create parts in SketchUp.
Next
- Use a a scale or, preferably, a vernier caliper to measure the parts you already have, then recreate them in SketchUp.
- I used an Arduino clone (induinoX).
- When creating the board in SketchUp create only the big parts that stick out to save time.
- Create the chassis in the shape you prefer.
- You can create slots by subtracting the slot's shape from the chassis.
Step #2: Google SketchUp assembly
Next
- Assemble the parts in Google SketchUp.
- See if all the parts fit together.
Step #3: Print the chassis
Next
- Print the outline of the parts for the chassis.
- Use the option that keeps the size of the printout to the actual size.
- Check the measurements after printing to be double-sure.
Step #4: Apply the template
Next
- Paste the printout on the material you want to cut the chassis from.
- I used 2mm acrylic sheet.
- Take care when pasting the printout that there are no creases in it.
Step #5: Cut out the shapes
Next
- Use a rotary tool or a hacksaw to cut out your shapes.
Step #6: Glue the parts
Next
- Use super glue to stick the parts together.
- I made the parts like jigsaw pieces so they meshed together to give more strength.
- Screw in the other parts like motors, caster wheels, etc.
Step #7:
- Finished chassis with the InduinoX board.
