Hexapod v1 STL

A 3D Printed Hexapod Robot

This agile, 3D-printed hexapod robot, built with ESP32 and Arduino, offers a range of advanced features, including:

• A robust, durable structure
• WiFi-enabled remote control
• Smooth, agile movement
• Over-the-air (OTA) firmware updates for easy maintenance

Working in progress

Check the following image for the initial positions of all the leg joints while all the servos are at 90 deg.

Adjust the following two lines in in config.h to correct the installation offsets.

static int left_offset_ticks[3][3] = {{-5, 10, 0}, {-15, 5, -20}, {20, -10, 10}};
static int right_offset_ticks[3][3] = {{20, -10, 0}, {-15, 0, -5}, {-10, 0, -20}};
