6.f. Laser Cutting Example: Calculator Robot Chassis
manufactures a robot based on a graphing calculator, which has a
chassis that is a good example of what can be made with a laser cutter. The dimensions of this chassis are designed
to fit a Texas Instruments graphing calculator on the top level and the electronics, batteries, and servos on the bottom
level. A similar design could be used for any basic robot.
This custom, two-level chassis is propelled by two radio-control
hobby servos modified for continuous rotation. The chassis uses
our
as a third
contact point. There are eleven laser-cut parts, with eight
different shapes; all parts are made of 1/8" acrylic (plexiglass),
except for a 1/4" spacer also made of acrylic. The pieces
interlock tightly enough that the chassis (barely) holds together
on its own; in this particular design, the parts are glued together.
A similar design could instead use a few screws or bolts should
the possibility of disassembly be desirable. The design has since
been changed to an ABS chassis that uses a “snap together”
design with tabs with small feet that snap into a smaller slot.
(This would not be possible using acrylic since acrylic is brittle.)
