Following the popularity of our self balancing scooter and the SciChair we decided to try something a little edgier, the Self Balancing Unicycle.
This project reuses a lot of stuff from our previous projects, using an arduino as the brains behind the scenes.
Step 1: Ready your tools
Before we begin lets ensure we have everything we need. For this project you probably want to be fairly comfortable with welding as you need to build a rigid frame.
Additionally you will need:
•Steel square tubing for frame
•24VDC 300W motor
•Arduino UNO - Check your local suppliers or eBay.
•Sabertooth 2x25 Motor Controller ( www.dimensionengineering.com or a local supplier)
•5 DoF analogue IMU - available on ebay (to be replaced with digital IMU at some point)
•Scooter wheel, sprocket, chain and axle - available as a kit
•Shielded multi core cable for the accelerometer and heavy power cable for the motors
•Toggle switch for adjusting balance position.
•DC connector for Arduino.
•DIL pins to suit Arduino
•Double sides tape
•Drill and drill bits
•Welding equipment and saftey gear
•Soldering iron and solder
•Wire cutter and wire strippers
•Heat shrink and hot air gun to shrink it
