Especially with metal the bit can snag as it s cutting and yank the piece out of your hands. If you can t place the work in the vise use a pair of Vise-Grips or other suitable locking pliers. FINISHING Cutting and drilling often leaves rough edges called flashing in the metal. These edges must be filed down using a medium- or fine-pitch metal file or else the pieces won t fit together properly. Aluminum flash comes off quickly and easily you need to work a little harder when removing the flash in steel or zinc stock. Build the Buggybot The Buggybot is a small robot built from a single 6-by-12-inch sheet of 1 16-inch thick aluminum nuts and bolts and a few other odds and ends. You can use the Buggybot as the foundation and running gear for a very sophisticated petlike robot. As with the robots built with plastic and wood we discussed in the previous two chapters the basic design of the all-metal Buggybot can be enhanced just about any way you see fit. This chapter details the construction of the framework locomotion and power systems for a wired remote control robot. Future chapters will focus on adding more sophisticated features such as wireless remote control automatic navigation and collision avoidance and detection. Refer to Table for a list of the parts needed to build the Buggybot.
