MEET PETOI BITTLE: A PALM-SIZED CUTE ROBOT DOG

From the era of UNIMATE (first programmable robot) to the modern ASIMO ( currently the world’s most advanced robot), the world of ROBOTICS and AI has made a tremendous amount of advancements. From the pages of science fiction stories to actual AI-powered news anchor and even more, robots are steadily progressing and becoming a crucial part of the industry, market, and even household. Today there are many kinds of robots developed according to the needs and demands in the market. Some robots have been developed in the form of pet animals one of which is the tiny and nippy PETOI BITTLE. Here is some information regarding this remarkable and amusing creation of modern-day robotics.

ABOUT BITTLE

  • OpenCat ( A programmable and highly maneuverable robotic cat for STEM education and AI-enhanced service ) was the idea that acted as a founder of pet projects. After the video on opencat became viral, PETOI developed their first robotic pet project NYBBLE – THE ROBOTIC KITTEN, and after the worldwide success of the NYBBLE project and experience from the OpenCat projects, PETOI developed their second project, this time a robotic dog – BITTLE, the sibling of NYBBLE.

PETOI NYBBLE-THE KITTEN
  • Evolved from an open-source gene, it’s like an open platform where we can attach sensors to provide perception or attach AI through wired / wireless connection. It can also use external sensors compatible with Arduino.
  • One can bring BITTLE to life by assembling its puzzle like frame and the company’s demo codes from GitHub.
  • This lightweight quadruped( four-legged) quite adorable robotic creature can perform tasks similar to your real pet dog. It can walk, run, jump, even sense. It will follow your every command that you will program in it.
  • Using a 3D printer we can modify its features like printing a different head or changing the size of limbs etc.

SIZE AND BODY SPECIFICATIONS

A PET ROBOT that is so tiny that it can completely fit in your hand. The robot has a body size of 20cm x 11cm x 11cm and weighs less than 280g, it uses x9 high-quality P1S Coreless Servos motors ( +1 additional as a spare unit) for smooth and precise movements. The brain of Bittle is NyBoard v1 ( for normal usage)  or BiBoard V0 ( more powerful,  for developers ).

BITTLE comprises of five major components:

1. BODY FRAME

The procedure of assembling the body of BITTLE is like solving a 3D puzzle. It takes about 1 hour to assemble it from the scratch.

2. ACTUATORS

There are 9 P1s servos to actuate BITTLE. Eight of them are installed for walking joints and the remaining is for the head, there is one extra servo for replacement in case of wearing.

3. ELECTRONICS

  • NyBoard V1 has an Atmega328P with 16MHz CPU, 2K SRAM, and 32K flash. An 8K I2C EEPROM, an IMU, a servo driver for 12 PWM servos, an infrared receiver, and a buzzer are also there in the system. It has a 2×5 socked to mount on a Raspberry Pi.
  • BiBoard V0 has an ESP32 with 240MHz dual-core CPU, 520KB SRAM, and up to 16M flash. It has built-in WiFi/Bluetooth, 12 PWM servo pins, an IMU, an infrared receiver, an audio amplifier, and a speaker. It has several communication ports to connect to other devices.

4. SOFTWARE

BITTLE is programmed with the OpenCat code. The most basic code is about 3 thousand lines of Arduino code that defines its quadruped motion. We can modify BITTLE’S code with other coding environments like C, Arduino IDE, and Python.

5. BATTERY

Li-ion battery with built in charging and protection circuit. It can provide BITTLE a continuous motion for about an hour.

COST…

The most attractive feature of Petoi Bittle is its affordable cost. The interest of such animal robots developed in the market since the launch of Boston Dynamic’s spot robot but its price was so high, about $75000, that only some people could afford it. The price of BITTLE is $195, which is quite affordable. Its affordable cost can be accounted for one of the many reasons for its worldwide success.
