Talk:Cheesoid

• interact with the fridge for cheese status
• interact with the petrol pump for petrol status

• it needs to know where they are to go and talk to them
• the status needs to be stored and needs to be set - Xino at each?
• it need to be able to read the status from the fridge and the petrol pump - what sort of interface? IR remote control?

Petrol status

• just a number!

Cheese status

• many cheese types - each with use by date
• Primula status is "in tube"

Motor skills

• get motors from post office - DONE
• simple test circuits with 12V battery and driver ICs
  • http://itp.nyu.edu/physcomp/Labs/DCMotorControl
  • http://www.ti.com/product/sn754410
  • datasheet: http://www.sparkfun.com/datasheets/IC/SN754410.pdf
  • PWM for speed control - a two motor library perhaps with feedback loop via rotary encoder?
    • using PWM on 2 motors http://letsmakerobots.com/node/2074
  • Adafruit motor shield is a good example:

    • My own custom motor shield for 2 DC motors
• mounting the motors and designing the axle couplings
• building the wheels : nearly done - some tweaking and securing to do
• building the plastic chassis - what's that display board plastic material called?
  • milling the plastic
  • strong enough to carry those batteries? !!!!
  • aluminium cross bracing?
• battery mount - where?
  • perhaps move to 2x 6V - keep it flexible
• battery regulation: http://letsmakerobots.com/node/3880
