Programmable wheel robot based on RK3399 works on multiple stages


The SLAMTEC Hermes robotic platform is a programmable wheeled robot that can support payloads of up to 60 kg on multiple floors through an optional elevator controller, making it suitable for hotels, hospitals, airports, warehouses, transport centers, surveillance robots, etc.

Powered by a Rockchip RK3399 motherboard, the Hermes robotic platform supports autonomous path finding, robotic collaboration, multistage delivery, intelligent obstacle avoidance, safety functions and autonomous charging. It can be controlled with a REST API, programmed with C ++ SDK, or a program called RoboStudio available for Windows and Android.

RK3399 SBC for robotic platform
Connection diagram RK3399 SBC

As I understand it, the Rockchip RK3399 single board computer is placed on top of the robotic platform to facilitate connection to the customer’s chassis, which, for example, allows you to use the HDMI and audio features of a host robot or any robot with a human machine. interface (HMI).

Several software tools are provided for the robot. The RoboStudio graphical control management tool for Windows and Android allows you to create, manage and edit maps for each of the robots in your fleet in a similar way to smart vacuum cleaners since it uses the same SLAM technology.

There is also a web portal to perform tasks like firmware upgrades, diagnostics, restarting the robot, etc. For more advanced customization, the company provides the SLAMWARE C ++ SDK to control most of the robot’s functionality. The Robot Agent interface is an HTTP API for controlling the robot over the network, and the company has developed an open source Android app for delivery use cases which can be found on Github. More details can also be found in the user manual.

SLAMTec intelligent elevator

If you want to use the cross floor function, you need to install the Slamtec ‘intelligent elevator control’ kit to upgrade your elevator and enable communication with the robotic platform, as shown in this short video embedded below .

The “Hermes Cross Floor Moving Robot Platform” was just listed on Seeed Studio for US $ 5,600, but is currently out of stock. The manufacturer’s product page (which loads very slowly) may contain more information.
