Introduction

Overview

The SDP Mini is a small-size development platform designed by SLAMTEC for evaluating the performance of modular autonomous robot localization and navigation solution(SLAMWARE solution for short).

It is assembled by key components including SLAMWARE Core, RPLIDAR A2 and Breakout 3.0 board, and requires only 8 AA batteries to run well without concerns about batteries and charging. 

The SDK of SDP Mini, supported to run in Windows/Linux/IOS and Android environment, integrates the whole SLAMWARE solution and extra reserved sensor interfaces. 

With SDP Mini, users can have a general understanding about the SLAMWARE solution and examine its basic performance. Run as the most compact structure which realizes the basic SLAMWARE solution, it is suitable for the preliminary evaluation of SLAMWARE solution or the development of robots with basic needs for localization and navigation function.

Key components

SLAMWARE Core

It provides autonomous localization and navigation based on RPLIDAR and supports for communicating the navigation information via serial port and Ethernet bus.

For detailed specification, please refer to SD001 SLAMWARE Core 数据手册.

SLAMWARE Breakout 3.0

As a shield for SLAMWARE Core, it provides the interfaces that can connect directly to RPLIDAR, network, PC, motor and varies sensors, which facilitates the software and hardware development based on the SLAMWARE Core.

RPLIDAR A2

It performs 2D 360-degree LIDAR scan in a range, and the generated 2D point cloud data can be used in mapping, localization and object/environment modeling. In SDP Mini, it provides raw data of the environment for SLAMWARE Core to analyze and handle.

Motor

The brush motor, with a simple schematic diagram, realizes the moving function of SAMWARE solution in SDP Mini, and it is easy to launch, control or improve.

Tools and usage

Tools with GUI

Robot Studio

It is a tool with graphical user interface for connecting to SLAMTEC devices. With this tool, users can control and debug SDP Mini in mapping, moving and other operations. 

Please refer to S002 Robot Studio User Manual for the detailed function description.

SLAMWARE Web Portal

SLAMTEC has designed a web portal tool to provide general operations for SLAMWARE devices during the  developing, debugging and using process. With this tool, users can check the basic information of SLAMWARE Core, update firmware, configure WiFi and diagnose the robot visually.

Currently supported operations are as below:

  • Check the device information
  • Restart module
  • Update firmware
  • Configure WiFi
  • Turn on SLAMWARE Core diagnose mode
  • Modify the password for administrator

Please check SQ001 SLAMWARE Web Portal Function Overview for detailed usage.

Mobile application

SLAMTEC has designed mobile application for SDP Mini. It covers the basic moving control, localization and navigation function. After binding the device to the mobile phone, users can control the SDP Mini successfully.

  1. The application in ios version is supported to run on and over ios 9.0; the one in android version is supported to run on and over android 4.4.
  2. Domestic users  can register this app via mobile phone number.

Other tools

Slamware Console

Slamware Console is a development tool for SLAMWARE SDK. It is used for debugging the implementation of Control Bus protocol, checking the sensor status configured in the base and the data of odometer and wheels. For details, please refer to SA001 Slamware Console Application Note.

slamware_config_tool

slamware_config_tool is a base configuration tool that can set the base diameter, the wheel base and the charging mode. For details, please refer to SA004 机器人底盘传感器位置坐标及底盘配置工具的使用.

  3. Unbinding SDP Mini and reset WiFi

when the SDP Mini is required to bind to another account of RoboHome mobile application or the network changes, the SDP Mini needs to be unbound first, and after resetting Wifi, it can be bound to another account or be found in a new network environment.  The steps are as below:

    1. Turn on the SW1 switch on the SLAMWARE Breakout 3.0 of SDP Mini to launch the device;
    2.  Log in to the RoboHome with the account which is bound with the SDP Mini → Refresh the Device Center and the bound SDP Mini will be online→ Click Edit in the upper right corner to enter editing mode→ Click the crash bin icon in the right of the SDP mini → Click Yes, delete in the dialog box.

    3. When the network changes, follow the following steps to switch the Station mode back to AP mode so that we can reassign the ip address:
      1. As shown below, remove the jumper in J22 on Breakout 3.0 board of SDP Mini and put it on the GND pin and RX2 pin of the same interface, then restart the SDP Mini. (Except for the buzz of normal launch, the SDP Mini will emit a longer buzz to indicate a successful WiFi reset. )

        After resetting, please turn the switch off and put the jumper back to normal state to ensure that the SDP Mini will work well later.

      2. After launching the SDP Mini, connect it to the computer with network cable, and then login to 192.168.11.1 in Chrome(Default username: admin; default password: admin111). Go to Administration on the upper right corner of the page → choose Configure WiFi on the left panel → choose Restore button in the bottom of the page.
