Compatible with
This is Totem’s adaptation of the robotics walking principle first invented by Joe Klann in 1994. It is therefore called a “Klann linkage”.
As you build, you will learn many cool mechanical principles that may be used in many other projects.
Due to advanced engineering, only 2 motors move all 8 Spider’s legs simultaneously.
Totem RoboBoard X4
Programmable robotics controller for wireless motor and sensor control
Totem RoboBoard X4 is an ESP32 robot development board with integrated Arduino programming and motor drivers. A compact package contains 11.1V battery with charging, DC and Servo motor control, accelerometer and gyroscope, wireless capabilities for remote control and Internet access. More features can be added using available Qwiic connector, TotemBUS port or GPIO pins for custom control and communications.
Documentation: https://docs.totemmaker.net/roboboard-x4/
Remote control
RoboBoard can be remotely controlled using Totem smartphone app with predefined controls or custom ones for your own project. Application allows to create buttons with variable parameters and intercept them in Arduino code.
All this functionality is integrated into Totem software and enabled with a few lines of code: https://docs.totemmaker.net/roboboard/api/totemapp/
Also, ESP32 enables access to the Internet or even interact with wireless gamepad controllers.
Software features
RoboBoard is well integrated with Arduino framework. Most of the features are accessible with single line of code without require for external libraries. Even allows to setup drivetrain algorithms or control motor speed and acceleration. See API specifications: https://docs.totemmaker.net/roboboard/api/
Compatible with Arduino IDE and PlatfomIO. Check for setup instructions: https://docs.totemmaker.net/setup/
Extensions
RoboBoard is a single board for all robotic needs. It contains some most common features, but can be expanded with additional Qwiic and TotemBUS modules. Even third-party modules works with integrated motor drivers. For custom controls or communications – available GPIO pins can be used (compatible with general Arduino libraries).
