Beetle robot project

thingiverse

This Beetle Robot is designed for a school project focusing on technique/electronics and/or 3D printing. Learning objectives: To master technology, physics, and electronics skills. Target audience: Students aged 11-16. Pre-requisites: Soldering skills are necessary. Materials: * 2 x Motors (1.5V) * 2 x Micro switches (NO, NC, + null contact) * 2 x Standard wires acting as antennae * 2 x AA batteries * 2 x LED lights (optional), 2 x resistors (220 ohms) (optional) * 1 x Master switch (optional) Full electrical diagrams are available in the provided JPG images. Objective: To create a running beetle robot that changes direction when an obstruction is sensed by the antennae. For reference, example walking beetle robot videos can be found here: https://www.youtube.com/watch?v=JBRWo6pHpaE https://www.youtube.com/watch?v=WcTu6T5hslk Print Settings: Printer: Craftbot Rafts: No Supports: No Resolution: 100-300 Infill: 15% Post-Printing: After printing, the print will form the backbone of the beetle robot. The two motors, switches, and batteries need to be inserted into the body. The soldering schematics can be found in the JPG image provided. The optional LED 'eyes' can increase complexity if desired. If added, resistors are also necessary. Design Process: This design was part of a physics project created for my nephew. The beetle's body was designed using OpenSCAD and will house two engines acting as front wheels/paws. Batteries can be positioned in the back, while the antennae on the front will trigger either switch. Optional LED lights are included at the front. The rear wheel ball is integrated directly into the print.
