What's the exact SBC that is used?


#1

“Quad Core ARM A9 - Raspberry Pi3”

  • how much ram?
  • what is the CPU speed?

#2

We use a Raspberry Pi 3 Model B+.

Specs:

  • SoC: Broadcom BCM2837B0 quad-core A53 @ 1.4GHz
  • GPU: Broadcom Videocore-IV
  • RAM: 1GB LPDDR2 SDRAM
  • Networking: Gigabit Ethernet (via USB channel), 2.4GHz and 5GHz 802.11b/g/n/ac Wi-Fi
  • Bluetooth: Bluetooth 4.2, Bluetooth Low Energy (BLE)
  • Storage: Micro-SD
  • GPIO: 40-pin GPIO header (used for connecting to the robot)
  • Ports: HDMI, 3.5mm analogue audio-video jack, 4x USB 2.0, Ethernet, Camera Serial Interface (CSI), Display Serial Interface (DSI)
  • Dimensions: 82mm x 56mm x 19.5mm, 50g

Thanks! Is that the only “computer” on the robot? Or are there one ore more arduino like sbcs?


#4

The motor controller board has an onboard factory programmed PSoC style microcontroller. The raspberry Pi runs linux and a host of other mostly ROS connected software. The host talks to the Motor Controller board using a serial protocol.

We have another sensor board under development that also uses an Arm style IO intensive processor.
