Beetle robot project

thingiverse

This is a beetle robot to make for a school project on technique/electronics and/or 3D printing Objective: Learn technology, physics and electronics Audience: Age 11-16 Preparation: Soldering Materials: 2 motors 1.5 Volt 2 micro switch (NO, NC + null contact) 2 standard wires to act as antenna 2 AA batteries 2 LED lights, 2 resistors (220 ohm) (optional) 1 master switch (optional) The full electric drawing is provided as on of the JPG images here directly Results: A running beetle which will change direction when the antenna senses an obstruction.

The two motors, switches and batteries need to be inserted into the body. The soldering schematics is provided in the JPG image provided. The two LED 'eyes' are optional and can be added to slightly increase complexity of the project when desired. If so, please also add the resistors. How I Designed This This design was part of a physics project we created for my nephew. The body of the beetle was designed in openscad and will house the two engines to act as front wheels/paws. The batteries can be positioned in the beetle robot's back. The front should be created by two wire antenna's which will trigger either of the switches. The two front LED's are optional The rear wheel ball is integrated in the print directly
