Here is small video clip of small demo how to control eduArdu robot with clap of your hands.

Rockchip is releasing low power SOC with NPU targeting deep learning.

1808

We are hacking cheap Chinese soldering robot aiming to make it usable with camera fiducials and solder joint inspection. I shared some info on Hackaday 2018 Belgrade conference.

As we want to make the robot easy to use we are looking around for capable SOC with Deep Learning capability. It seems the only embedded available solution now is nVidia.

Allwinner has put in their V5 SOC info about AI and Trensorflow support, but looking at info for the only available board on the market it looks just statement and no actual implementation.

The AI they advertise looks more like OpenCV / Tensorflow lite libraries using the V5 GPUs, but not real NPU.

Rockchip seems to be this time a little bit ahead of Allwinner and has released RK1808 and RK3399pro SOCs.

Some info also start to appear in their rockchip-linux repositories.

We got RK1808 brief datasheet and here are the SOC internals:

  • Dual core Cortex-A35
  • Internal 2MB SRAM
  • DDR 32-bit data width, 2 ranks max 2GB of DDR3/DDR3L/LPDDR3/LPDDR3L -1600
  • Neural Process Unit with 512KB internal buffer and Support for: max 1920 Int8, max 192 Int16 and max 64 FP16 MAC operations per cycle
  • eMMC 4.5 1-4-8 bit max 150MB/s
  • SD/MMC support
  • SPI Flash x1-4-8 data
  • video encoder/decoder up to 1080p
  • video input DPI 8-10-12-16 bit up to 150MB/s
  • camera input MIPI CSI up to 4 data lane, 2.0Gbps, MIPI-HS, MIPI-LP
  • LCD RGB 8/8/8 up to 1280×800@60fps
  • MIPI DSI 1920×1080 up to 4 data lane, 2.0GbpsA
  • Audio I2S
  • Gigabit Ethernet
  • USB2.0 HOST/OTG
  • USB3.0 5Gbps
  • PCIe 1/2 links with 2.5Gbps per link
  • SPI, I2C, UART
  • x4 10bit SAR ADC 1Msps
  • -40+125C operating temperature, targeting automotive and industrial vision apps

This chip is definitely not hobby friendly with FCCSP 420 0.3mm balls spaced at 0.5/0.35mm!

Price info is not available yet. First evaluation boards will be ready end of March 2019. Rockchip will sell SDK with the NPU API also at unknown yet price.

Rockchip also upgraded their RK3399 including inside RK1808 and naming it RK3399Pro.
They keep the same RK3399 ball layout, so people who already made RK3399 boards can upgrade with RK3399Pro without changing lot on their PCB layout.

How they do it? They bond RK1808 in the same package and connect RK3399 with RK1808 via USB3.0 this is why RK3399Pro has NO externally available USB3.0:

How they will manage power dissipation when they put together two quite power hungry chips is yet to be seen. RK3399 alone requires quite big heatsink as it dissipates up to 20W when the Cortex-A72 cores are running.

New Robot Chassis in stock: ROBOT-2WD-KIT2

ROBOT-2WD2-6

We have new Robot Chassis in stock! It’s with two gear motors, two aluminum plates, free castor wheel, two 60 mm wheels attached to the motors, all necessary fittings.

The assembly is very simple:

The castor wheel is attached to bottom plate:

ROBOT-2WD2-2

ROBOT-2WD2-1

To the gear motor is attached small aluminum plate:

ROBOT-2WD2-3

then the 60 mm wheel:

ROBOT-2WD2-4

Four heximal spacers are assembled to the plate with the castor wheel:

ROBOT-2WD2-5

Then the two gear motors aluminum plates are fixed between upper and bottom plate:

ROBOT-2WD2-6

and the chassis is ready!

Now we are thinking for possible custom control board with these features:

  • Arduino like main board allowing easy re-programming
  • Motor drivers
  • Motor encoders which to give feed back to Arduino with photo interrupters
  • LiPo Battery charger and step up converter for motor and Arduino powering
  • UEXT for ESP8266 WiFi
  • two sockets for Ultrasonic distance sensors on the two sides of the castor wheel
  • (optional RT5350F-OLinuXino with camera)
  • connectors for optional servo motors for robot hand
  • UEXT second connector for attaching more sensors

Let us know if we missed something 🙂
