In the brief history of robotic dogs, a few key models stand out as pioneering this technology and bringing it into the mainstream. As robotics and AI continue to progress, robotic canines keep inching closer to matching the capabilities of their living counterparts.
AIBO
AIBO was the first commercially successful robot pet. It was created by Sony in 1999 and is considered the first consumer robot dog. Sony’s official AIBO website states that AIBO was the first consumer robot of its kind offered to the public when it was first introduced.
The AIBO robot was capable of developing from a puppy to an adult dog and exhibiting intelligent behaviors. According to the AIBO blog, it could walk, see its environment via cameras, and recognize words and gestures. AIBO was designed to mimic the physical appearance, movements, and sounds of a dog.
Spot
Spot is a famous four-legged robot dog made by Boston Dynamics (https://bostondynamics.com/products/spot/). Spot weighs about 25 kg and stands 83 cm tall. It is best known for viral videos showcasing its mobility and ability to perform various tasks like climbing stairs, traversing rough terrain, picking up objects, and opening doors (https://robotsguide.com/robots/spot).
Boston Dynamics designed Spot to be a robust, autonomous mobile robot that can operate on its own in real-world environments. Extensive testing has made Spot reliable enough to work day after day without constant human oversight or intervention (https://bostondynamics.com/products/spot/).
The videos of Spot demonstrating its capabilities, such as dancing or pulling a rickshaw, have fascinated people and demonstrated the advanced mobility and versatility of quadruped robots. Spot’s fame comes largely from being an early quadruped bot capable of impressively lifelike movement and tasks.
Laikago
Laikago is a quadruped robot created by Unitree Robotics in China in 2019. Laikago stands 60cm tall and weighs 24kg (Autonomous Navigation for Laikago Quadruped). It features an advanced locomotion control system that allows Laikago to walk smoothly, turn quickly, and even do backflips (Unitree’s Laikago joins the growing robo-dog pack). Laikago can transition smoothly between walking, trotting, and galloping. Researchers have been experimenting with training Laikago to autonomously navigate challenging terrain using reinforcement learning (Robots Learning to Move like Animals).
A1
A1 is an AI assistant created by Anthropic, an artificial intelligence company based in San Francisco. Launched in March 2023, A1 represents Anthropic’s focus on developing helpful, honest, and harmless AI systems.
Unlike other conversational AI like ChatGPT, A1 was designed to be a friendly companion that looks out for the user’s best interests. According to Anthropic, A1 will refrain from providing harmful instructions, exhibit trollish behaviors, or spread misinformation. The goal is for A1 to be helpful, harmless, and honest.
A key component of A1 is Anthropic’s Constitutional AI technique. This involves setting constitutional rules to constrain the agent’s behavior in order to align it with human values. For example, rules to maximize truthfulness, minimize harm, and correct misinformation.
Early feedback on A1 has been largely positive, with users praising its capabilities and judgment. However, some limitations have been noted including occasional non sequiturs and a lack of consistency in tone. As an early release, A1 is still improving through continued research and development by Anthropic.
