Anim4Bot

For the second version of Animabot I want something different. I don’t want to see the motors or the electronic. I also want him more powerful, more intelligent and more friendly !

So for the design I opted for a full 3D printed body, which allow me smooth forms, and complex shapes. For the design I will inspire me from  Norio Fujikawa which has made this one :

The design will be complex to do, but I think I am able to do it 😉

For the intelligence I will use 2 boards :

• Raspberry Pi model B

• The Broadcom BCM2835 ARM11 700Mhz “System On Chip” Processor
• Integrated Videocore 4 GPU capable of playing Full 1080p
• 512MB RAM
• Debian GNU/Linux Operating System
• 2 x USB Ports
• HDMI Video Output
• RCA Video Output
• 3.5mm Audio Output Jack
• 10/100Mb Ethernet Port
• 5V Micro USB Power Input Jack
• SD, MMC, SDIO Flash Memory Card Slot
• 26-pin 2.54mm Header Expansion Slot

• STM32F4 Discovery board
  

• STM32F407VGT6 µC featuring 32-bit ARM Cortex-M4F core, 1 MB Flash, 192 KB RAM
• On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone ST-LINK/V2
• Board power supply: through USB bus or from an external 5 V supply voltage
• External application power supply: 3 V and 5 V
• LIS302DL or LIS3DSH ST MEMS 3-axis accelerometer
• MP45DT02, ST MEMS audio sensor, omni-directional digital microphone
• CS43L22, audio DAC with integrated class D speaker driver
• Eight LEDs:
• LD1 (red/green) for USB communication
• LD2 (red) for 3.3 V power on
• Four user LEDs
• 2 USB OTG LEDs LD7 (green) VBus and (red) over-current
• Two push buttons (user and reset)
• USB OTG FS with micro-AB connector
• Extension header for all LQFP100 I/Os for quick connection

Why these 2 ones ? because the Raspberry is powerful, runs on Linux, is cheap and has an huge community. The second one because it has a lot of pins (breakout board) which allows me to connect sensors and also drives all the servomotors.

This time I made a proper architecture :
