How to Make an Obstacle Avoiding Robot with MiniQ 2WD

project by Phoebe

Now you can make your own custom version of obstacle avoiding robot. Assemble the robot, wire up the modules, upload the code, and add your own flavor. Cruising with a swaying IR sensor and a mp3 player onboard, this DIY obstacle avoiding robot has a new added feature: vocal.

Materials

• 2WD miniQ Robot Chassis
• Upper Deck for miniQ
• Romeo V2 All in one Controller
• 9g micro servo (1.6kg)
• Sharp GP2Y0A21 Distance Sensor (10-80cm)
• Sharp IR Sensor Mounting Bracket - GP2Y0A21/GP2Y0A02YK
• 7.4V Lipo 2200mAh Battery (Arduino Power Jack)
• DFPlayer - A Mini MP3 Player
• Speaker
• M3*30 nylon standoffs
• M3*20 nylon standoffs
• M3*10 nylon standoffs
• M3 nuts
• M3*6 screws
• M2*6 screws
• M2 nuts
• M3*7 Black nylon gaskets

Tools

• Screw Driver
• Knife
• PC
• MicroUSB Cable

Step 1: Assembling the miniQ with upper deck

Step 2: Wiring the modules

This is what it looks when finishing assembling and wiring the physical parts. Cute!

Step 3: Programming

For time's sake, I am not gonna walk through all the codes and explanations here. Tips of using the DFPlayer Mini mp3 module can be found here. I used the sound files of popular tower defense game Carrot Fantasy when the robot encounters an obstacle. Alternatively, you can also change it and place other audio files as you wish, to make it even more funny. Anyway, the Arduino Code and Sound Effects Pack are shared below. Looks and plays great.
