Version: ROS 2 Humble

Platform Overview

Every robot platform has unique structures such as versatile sensor mounting solutions, wireless charging receivers, and waterproofing enclosures; we refer to these as attachments.

Additionally, each robot also supports specific batteries and battery configurations that must be set accurately to ensure proper battery management.

Furthermore, the robot platform nodes can be modified by the user through the extras section. In particular, an extra URDF can be appended to the robot's URDF, a launch file can be added to the robot's launch file, and ROS parameters can be modified directly by setting the key, value pairs.

The platform section is divided into the following sections:

Sample

Sample A200 Platform Section

In this sample, we swapped the top plate from the default model to the pacs model. Notice all the links added by the pacs plate below, compared to the default plate above.

  - name: top_plate
    type: a200.top_plate
    model: pacs # switched from 'default' to 'pacs'
    parent: mid_mount
    xyz: [0.0, 0.0, 0.0]
    rpy: [0.0, 0.0, 0.0]
    enabled: true

Then, we added a sensor arch to add our sample sensors to. We can do this by adding the attachment, sensor_arch and setting the model to sensor_arch_300.

  - name: sensor_arch
    type: a200.sensor_arch
    model: sensor_arch_300
    parent: mid_mount
    xyz: [0.0, 0.0, 0.0]
    rpy: [0.0, 0.0, 0.0]
    enabled: true

In terms of the front_bumper and rear_bumper, we left these as defaults. And, since we are not including any customization URDF or launch parameters; the resulting platform section look like this:

platform:
  battery:
    model: ES20_12C
    configuration: S2P1
  controller: ps4
  attachments:
    - name: front_bumper
      type: a200.bumper
      model: default
      parent: front_bumper_mount
      xyz: [0.0, 0.0, 0.0]
      rpy: [0.0, 0.0, 0.0]
      enabled: true
      extension: 0.0
    - name: rear_bumper
      type: a200.bumper
      model: default
      parent: rear_bumper_mount
      xyz: [0.0, 0.0, 0.0]
      rpy: [0.0, 0.0, 0.0]
      enabled: true
      extension: 0.0
    - name: top_plate
      type: a200.top_plate
      model: pacs
      parent: mid_mount
      xyz: [0.0, 0.0, 0.0]
      rpy: [0.0, 0.0, 0.0]
      enabled: true
    - name: sensor_arch
      type: a200.sensor_arch
      model: sensor_arch_300
      parent: mid_mount
      xyz: [0.0, 0.0, 0.0]
      rpy: [0.0, 0.0, 0.0]
      enabled: true
  extras:
    urdf: {}
    ros_parameters: {}
