Designing a Robot Chassis

Use Google SketchUp to design and fabricate a chassis for your robot.

Designing a Robot Chassis

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

Steps

Step #1: Create parts in SketchUp.

  • 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

  • Assemble the parts in Google SketchUp.
  • See if all the parts fit together.

Step #3: Print the chassis

  • 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

  • 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

Use a rotary tool or a hacksaw to cut out your shapes.

Step #6: Glue the parts

  • 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.
