Looking at my overall objective for the challenge I've broken down the work into some steps.
- Motors testing
- Furby testing
- Lighting
- Power supply
- Driving motors
- O/S and prerequisites
- Playing sounds / speech
- Activating the Furby
- Software
Motors testing
Review the car motors to see what voltage and current they require. Ensure that the car platform still works.
Furby testing
See how the Furby is put together, look at controlling the main drive motor and reading sensors. Look at the speaker to see what we need to drive that.
Lighting
For the car lighting, look at what we need to drive some LEDs for the headlights, indicators and brakes. Assemble sub boards that can be plugged into the grove connectors to power them. If I have time I'll take the suggestion from Jason and implement the light sensor so that the headlights can come on automatically.
Power supply
Review the Edison's power requirements, add to that the various motor and LED requirements. Ensure we have a battery that is capable of providing the voltage and current demands and has sufficient capacity for a reasonable run time.
Driving motors
Connecting the motors up to the H-Bridge, controlling speed and direction from the Edison.
O/S and pre-requisites
The system relies on some form of operating system to host the software so time will be needed to check versions, ensure I've got Node and a MQTT broker running and hook it up to the Wifi.
Playing sounds / speech
Getting the sound card connected to the Edison, reading files from the SDCard and playing them through the headphone connector. Connecting that up to the Furby speaker and reviewing if it will need an additional amplifier
Activating the Furby
Getting the Furby controlled from the Edison.
Software
Controlling the hardware, looking at what we need so that the car can turn through 90° in each direction
Car Chassis
Putting the physical aspects of the project together. See if we can put some microswitches or other sensors into the bumpers.
