Cutsie Whun

A simple and cheap three wheeled time waster for almost any skill level. Basic stats are Arduino Mini Pro, Sonic distance, and a Gyro.

Things used in this project

Hardware components

SparkFun Arduino Pro Mini 328 - 5V/16MHz

SparkFun ZX Distance and Gesture Sensor

I used the HC-SR04

Digilent Pmod GYRO

Needed only if you want it on two wheels

RobotGeek Continuous Rotation Servo

Need only be a suitable 360 rotation servo, the faster the better.

Li-Ion Battery 1000mAh

I used a 2000mAh cell phone battery, nice and flat.

OpenBuilds Delrin V Wheel Kit

I used the wheels from a spectacular model F4U-1 Corsair aircraft crash.

Software apps and online services

Arduino IDE

Hand tools and fabrication machines

Soldering iron (generic)

plastic saw

Hot glue gun (generic)

Story

MEGA BREAD - Cutsie Whun

MEGA BREAD SERIES Number 8, A very simple and time wasting implement for almost any skill level.

Updated 5-26-2017

Part 1

Twin servos on the drive wheels, 12G size, metal aircraft grade, high speed low drag devices. Sonic distance sensor, with a Mini Pro as a brain. The balance and layout will allow for twin super mini servos for sonar location device movement. It has a 6 Position Gyro allowing it to Stand up on two wheels, Or set itself down and haul maul to wherever. Small adaptations seem to be able to be implemented with very little trouble.

Side view showing the basic layout

The wheels are from a spectacular, and expensive model F4U-1 aircraft crash. The Case is made from a wall mounted motion sensor.

Part 2

As you can see, there is plenty of left over space at the top for the mounting of the Sonic sensor motion control needs. The Gyro sits directly behind the main brain. Power is a 2000 Mha Cell Phone LiOn battery, Nice and flat, It slides in between the top of the brain board, and the facing side. This Wide Load base gives it excellent ballance, and speed when needed is also available.

UPDATED PICTURE below.

Moved and relocated the flat battery pack to the underside (The back when upright), I was experiencing heating issues and to be safe, moved them.

Please use caution with these battery packs from the cellular phones, any damage can lead to a very devestating fire outbreak.

Will update as needed.

This will do a VERY VERY basic wheel spin changing
the direction of wheel spin every 3 seconds

Auto Navigation not yet implemented
