What's the exact SBC that is used?

“Quad Core ARM A9 - Raspberry Pi3”

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

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?

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.
