The hexapod ladybug model has been made parametric, allowing for easy adjustments through the "equations.txt" file. This file contains variables such as 'gap', which determines separation between parts, and 'min_wall' for minimum wall thickness. A YouTube video on hexapod kinematics provides further insights (http://www.youtube.com/watch?v=ACaJE-fd9RU). For the build, required items include a BotBoarduino at $34.95 (http://www.lynxmotion.com/p-840-botboarduino.aspx), a PS2 Robot Controller for $19.95 (http://www.lynxmotion.com/p-552-ps2-robot-controller.aspx), 18 Micro Servo Arrow 4.3g/.8kg/12sec at $55.44 (http://www.hobbyking.com/hobbyking/store/__3724__Arrow_4_3g_8kg_12sec_Micro_Servo.html), and a Turnigy 1000mAh 2S 20C battery for $4.30 (http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9170). The total electronics cost is $110.34, excluding shipping fees. Printing service costs are estimated at $1.4 per cubic centimeter for 500 to 350 cubic centimeters objects with wall thicknesses of 3mm and 1.5mm respectively. The creator mentions having no prior experience in robotics or electronics, and the model was created for a 3D Printing Event Challenge.
