Once you've built the standard Strawbot, whether it's Harvey 1.0, Harvey 2.0 or the instructables robot, you may want to venture further. This short instructable will send you in the right direction.

Step 1: Colour and Face
Step 2: Weapons and Accessories
It's probably just easier to come up with your own designs. The more punch sizes you have and the more straws you have will determine the complexity of designs you can come up with. I find that the super long bendy straws that I imported from China add the best details to my Strawbots.
The jet pack was designed be one of my students, who decided to take the leg template piece from Harvey 1.0 and re-purpose the design. BRILLIANT!! Why didn't I think of that.
The possibilities are endless. Have fun with it and see what you can come up with.
