TiLDA Balance

First entry of https://wiki.emfcamp.org/wiki/Badge_Creations !!!

I'm working on making use of the TiLDA with its MPU-6050 as the brains of a balancing platform (initially a little balance-bot but eventually a ridable Segway-like platform if all goes well). The MPU-6050 has a 3-axis gyroscope, 3-axis accelerometer, and a Digital Motion Processor(TM) (DMP) integrated into a tiny little package on the back of the badge (IC2). It can do a lot of the grunt work leaving the badge micro plenty of space and time to do the other cool stuff.

  TiLDA

• Getting to grips with development on TiLDA: see EMF wiki for the most part (https://wiki.emfcamp.org/wiki/TiLDA_MKe)
• https://github.com/emfcamp/Mk2-Firmware
• MPU-6050
  • MPU = Motion Processing Unit
  • compare TiLDA usage with that of Sparkfun breakout schematic at https://cdn.sparkfun.com/datasheets/Sensors/IMU/Triple_Axis_Accelerometer-Gyro_Breakout_-_MPU-6050_v12.pdf
  • orientation of the device and mapping to "normal" badge orientation
• libs... TODO
• Cheap little motors: I want a quick and cheap entry point for people to achieve first before forking out for expensive parts. With this in mind I am trying out these little almost ubiquitous gearmotors: zzzzzzzzzzz
• Cheap motor drivers: ubiquitous L298N module
• Battery power: separate power supply from rechargeable AA batteries direct to motor driver.

Stretch Goals

• Ball balancing: http://youtu.be/dr5xdpLL58A
• Total Segway domination - human or multi-human carrying!
• wheel-less eerie ball/egg
