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 Datasheet。

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

SLAMWARE 设计有Robot Studio，一款极为友好的电脑端图形界面工具，涵盖了SLAMWARE解决方案的绝大部分功能操作，用户使用该工具连接至设备，即可对设备进行建图，运动，导航，虚拟墙等一系列操作。

了解Robot Studio功能，请参考SQ002 Robot Studio Cheat Sheet。

SLAMWARE Web Portal

在开发、调试及使用SLAMWARE设备的过程中，有时候需要对设备进行一些操作，如查看基本信息，更新版本，配置WiFi，可视化诊断等，通过Web Portal管理后台即可方便地进行这些操作。

当前该管理后台可支持的操作包括：

  • 查看设备信息
  • 重启模块
  • 更新固件
  • WiFi配置
  • 开启SLAMWARE Core诊断模式
  • 修改管理员密码

请参考SQ001 SLAMWARE Web Portal Function Overview了解该管理后台所有功能及使用方法。

Mobile application

SLAMTEC设计有可分别运行在ios和Android设备上的应用程序，涵盖了定位导航机器人所需要的基本建图和运动控制功能，添加好需要操控的设备即可对设备进行一系列控制，方便用户对解决方案进行评估和调试。

Other tools

Slamware Console

Slamware Console是配套Slamware解决方案使用的一个命令行开发工具。这个工具的主要用途是调试您底盘的Control Bus协议实现是否正确。同时也可以用来诊断您的底盘上的各个传感器的状态，以及里程计和轮子的数据。请参考SA001 SLAMWARE Console Application Note了解详情。

slamware_config_tool

底盘配置工具slamware_config_tool可以设置底盘大小，轮距，自动回充等参数，详情请参考SA004 机器人底盘传感器位置坐标及底盘配置工具的使用。

Reference

FAQ

  1. When the network changes, how 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 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.
