Follow our step-by-step guide to create the Asi Anansi, a unique spider-like robot companion, and explore other exciting hardware projects on Hackster.io.

Introduction

In today’s rapidly evolving technological landscape, robot companions are becoming indispensable tools for enhancing productivity and providing emotional support, especially for remote workers and students. The Asi Anansi, a spider-inspired robot companion, is a prime example of how robotics can blend functionality with personality to create engaging and interactive desktop pets. Inspired by African folklore, Asi Anansi not only serves as a delightful distraction but also fosters a sense of companionship and motivation in your workspace.

Materials Needed

To build the Asi Anansi, you’ll need the following hardware components:

Arduino Nano R3
SG90 Micro-servo motor (1x)
Available at Newark or CPC
MAX7219 Red LED Dot Matrix Display Module (1x)
Available at Newark or Adafruit
4xAA Battery Holder
Alternatively, a 3.7V lithium-ion battery (200mAh) can be used
Clear Plastic Acrylic Bath Bomb Mold Shells (1x)
Adafruit Trinket – Mini Microcontroller – 5V Logic (1x)
Screws and Various Hand Tools
3D Printer and Hot Glue Gun
For assembling custom parts and enclosures

Step-by-Step Assembly

1. Designing the Frame

Begin by designing the spider-like frame using a 3D printer. Customize the legs and body to ensure stability and aesthetic appeal. You can reference the original Asi Anansi designs available on Thingiverse.

2. Installing Electronics

Mount the Arduino Nano R3 and Adafruit Trinket onto the designated sections of the robot’s body. Ensure that the SG90 Micro-servo motor is securely attached to facilitate head movements. Connect the MAX7219 LED Matrix Display to the microcontrollers, allowing for expressive eyes that respond to user interactions.

3. Power Management

Wire the 4xAA battery holder or the lithium-ion battery to power the robot. It’s advisable to use two lithium batteries connected via the same on/off switch to ensure consistent power delivery and prevent malfunctioning.

4. Final Assembly

Assemble the head using a clear acrylic sphere, spray-painted with black to simulate eyes. Attach the head to the neck piece using hot glue. Finally, use armature wire to string the legs through the body, ensuring mobility and balance.

Coding the Robot Companion

The Asi Anansi operates using a combination of the Arduino Nano and Adafruit Trinket microcontrollers. Below is a simplified overview of the code structure:

#include <LedControl.h>
#include "LedControl.h"

// Define connections for LED matrix
#define PIN_EYES_DIN 12
#define PIN_EYES_CS 11
#define PIN_EYES_CLK 10
LedControl lc = LedControl(PIN_EYES_DIN, PIN_EYES_CLK, PIN_EYES_CS, 2);

// Define eye patterns
byte eyeBall[8] = {
  B00111100,
  B01111110,
  B11111111,
  B11111111,
  B11111111,
  B11111111,
  B01111110,
  B00111100
};
byte eyePupil = B11100111;

// ... (additional code for eye movements and servo control)

This code manages the LED displays for the eyes and controls the servo motor for head movements. Customize the code to add more interactive features such as voice commands or game-playing capabilities.

Customizing Your Asi Anansi
