reflex game for cats

This sleek, electrically powered cat toy brings excitement and exercise to your cat’s daily routine! A moving object circles around to mimic prey, activating your cat’s natural hunting instincts. Perfect for solo play or entertaining to watch, it keeps your feline friend physically and mentally stimulated.

Key Features:

• Automatically moves in a circular pattern
• Encourages activity and sharpens reflexes
• Stylisch mouse/hamster optic
• designed to be build easily and with tools you habe at home

hardware list:

• 4 listed 3D-parts
• arduino uno
• connection cable for power
• glue
• double-sided tape
• servo motor
• connection cables (red, brown, orange)
• 2x M2 screws

optional:

• power supply battery and connector cable
• cable ties or tape for connection cables

Wiring:

• orange cable - pin 9
• red - power supply 5V 
• brown - GND

for detailed view, see pictures

Assembly:

1. Attach servo motor to the bridge and secure it using 2x M2 screws. Make sure to put the cables of the servor motor through the hole.
2. Attach double sided tape to the ground plate. The tape is used to secure the arduino. Make sure that the tape is as thick as possible. Otherwise the soldering rest prevents the board from sticking to the ground plate. You can also use silicon or liquid adhesive but then you wont be able to reuse the arduino. Furthermore make sure the power connector is pointed in the right direction (towards the lower hole in the dome).
3. Use liquid adhesive to glue the bridge (=holder for servo) to the ground plate. 
4. Connect the cables of the servo motor to the arduino pins as can be seen on the pictures. The red cable is the power supply for the servo. The brown cable connects to ground and the ornage one to the pin 9  and is there for communication between the servo and arduino.
5. If you want to use a battery, use the double sided tape to attach the battery to the ground plate. Be careful to where you attach the battery. The dome should still fit on the ground plate. 
6. Push the stick on the servo motor.
7. Connect the arduino to your pc, copy the code and paste the code to your arduion sketch and upload the code via arduino software to your arduino. The servo motor should move now.
8. Attach the dome to the ground plate by simply sticking it on. 
9. Attach the toy/thing your cat is supposed to chase to the stick. 
10. Connect the arduino to the power source of your choosing.

Code:

#include <Servo.h>  // Servo-Bib

Servo meinServo;  // Create Servo-Object

void setup() {

  meinServo.attach(9);  // Servo  Pin 9

  randomSeed(analogRead(0));  // random number generator

}

void loop() {

  int zufallsPosition = random(0, 181);  // random position between 0 and 180 degrees

  meinServo.write(zufallsPosition);  // Move sevo to random position

  delay(50);  // wait 50 mili-secs before moving to new position

}

Printing instructions:

• material: PLA
• nozzle: 0.4 mm
• layer height: 0.2 mm
• infill: 15 %
• walls: 2
• walls top/bottom: 3
• supports: only for dome around top hole

additional info:

• print holder for servo motor laying on its side
• print staff standing 
• The stick combined with tape is there to simulate a real cat toy. I recommend using one of those wool-toys that look like a tail of a mouse
• You could also attach a laserpointer to the stick/staff/mount
