Parker1

Parker1 is a low-cost WiFi / 4G mobile robot with vision ability. It runs with two popular open source software, Arduino compatible code for easy robot programming, and OpenWrt router OS for a variety of connectivity over WiFi, 4G etc.

Let the users get playing on Parker1 just with a browser device on hand. Parker1 is preloaded with a basic, in full-function codes. And the source codes would be open on internet, hopefully turns into a community-based support system.

How to Command Parker1 on Play?

The motion control of Parker1 is quite simple. The user opens a browser window and issues the motion control commands (in ASCII char format) to Parker1 via cgi-script. Then OpenWrt passes it as serial data to ATMEGE328, which runs an Arduino serial monitor and executes the motions accordingly.

As the Arduino lovers, you can just focus on Arduino coding upon the commands received from the serial monitor. And it is possible to add-on extra sensors / circuits with the ATMEGA328 IO pinout header on board. The data pass-over by OpenWrt is transparent to you, the preloaded firmware already take care of it. The video streaming is enabled at boot time, just let the users get started with no panic!

If you are familiar with OpenWrt, Parker1 gives you the freedom in network and webcam config customization.
