Battery Life and Maintenance for Robot Pets [Everything You Need to Know]


Robot pets come in a wide array of designs and functionalities, catering to diverse needs. While some are crafted as companion animals, others serve law enforcement in high-risk scenarios.

The price spectrum for robot dogs is vast, with the costliest models featuring advanced AI technology to replicate canine behavior. These mechanized canines elicit mixed sentiments among people, yet they present a viable alternative for those lacking the time or capacity to care for a live dog.

What are Robot Pets?

A robotic pet is a robotic device engineered to emulate the appearance and conduct of real pets, often dogs or cats. These machines often employ cutting-edge sensors and intricate programming to simulate real pets’ movements, sounds, and behaviors. Their applications span entertainment, education, research, and therapy.

Specifically, robot dogs are versatile, and geared to perform an array of tasks based on their intended function. Some serve as entertaining toys or companions for those unable to have a live pet, with programming enabling them to undertake actions such as walking, running, barking, or even juggling.

These devices may be equipped with advanced sensors and cameras, facilitating navigation through intricate surroundings, data collection, or task execution. Additionally, robot dogs contribute significantly to research and development, aiding in the comprehension of animal behavior and the advancement of diverse technologies. In essence, the robot dog proves to be an adaptable tool applicable across a broad spectrum of industries and domains.

All About Batteries in Robot Pets

Similar to computers, robots also have a memory unit supported by a backup battery. These memory backup batteries provide a low voltage to sustain the memory circuits’ operation. It’s important to differentiate these from the power batteries found in cordless devices like laptops or cell phones.

Conducting routine maintenance on robotic systems, which includes replacing batteries, is a fundamental practice for ensuring consistent performance and maintaining quality control.

Backup Batteries: Purpose and Types

Robotic systems, unlike cell phones, laptops, and other wireless devices, rely on AC power and do not function using standard power batteries. Instead, the primary role of a robot system’s battery is to provide a consistent and low-voltage supply for memory backup and file storage. Depletion of this battery can result in memory loss, including the loss of the system’s original settings.

Maintenance of backup batteries is essential for two key components within a robot system. The first component pertains to the robot arm axis. In most systems, individual batteries are assigned to store origin data for each axis of the robot. Origin data comprises calibrated points for each axis, defining their complete degrees of freedom.

Often, when recalibrating origins, positions within a program may need to be re-taught because the starting point of zero-zero-zero has been altered. The second vital component is the controller, often referred to as the “brain” of the robot system, which relies on backup batteries for program file memory. These controller batteries typically resemble the shape and design of small calculators or watch batteries.

Maintainance of Battery Life

Maintenance schedules and methods for monitoring machinery are industry standards in automation. Most robot manufacturers recommend an annual battery replacement.

Robot systems typically employ a time or hour-based schedule to determine when the backup battery needs to be replaced. Additionally, they may incorporate an alarm or warning system to signal a low battery condition. This alarm is linked to the system’s calendar data, which was established during the battery’s last installation.

It’s important to note that this alarm does not produce an audible sound but instead issues a warning about the low battery status. This warning may manifest in several locations, including the teach pendant (the device used for remote robot control) and the controller. Furthermore, the inability to save a program or encountering various position errors may also serve as indicators of a low battery.

How to Charge Your Robot Pet

Charging procedures for robot pets vary, contingent on the specific model and manufacturer. Most robotic pets are typically accompanied by a charging cable or docking station for recharging the internal battery.

Here are the steps involved in the charging process:

  1. Consult your robot pet’s manual to identify the required charger type and any specific charging instructions.
  2. Connect the charging cable or dock to a power source, such as a wall outlet or USB port.
  3. Attach the charging cable to the robot pet’s charging port or place the robot dog on the charging stand, depending on the model.
  4. Allow the robot pet to charge fully, which can take several hours, contingent on battery size and charging speed.
  5. Once the robot dock is fully charged, unplug the charging cable or remove it from the dock.

Adhering to the manufacturer’s instructions diligently is crucial to prevent damage to the robot dog’s battery or electrical system. Additionally, avoid overcharging the robot dog, as it can harm the battery.

The lifespan of a robot pet is influenced by factors such as component quality, usage frequency, maintenance, and care. A well-maintained robotic dog can endure for many years, but it’s essential to acknowledge that technology is progressing rapidly.


Robot pets come in diverse forms and sizes, serving a multitude of environments. While they cannot completely replace live pets with their current technology, they present a viable option for individuals unable to care for real pets.

The future holds potential for further advancements in research and technology, potentially expanding the scope of applications for robot pets across various settings.

Linda Takahashi

American-born New Yorker Linda Johnson has been fascinated with robotic machines since she was a teenager, when her father, a surgeon, would introduce to her the machines that he used to perform keyhole surgeries. This interest led her to pursue a tech degree at the University of Washington, where she met Sota Takahashi. They married and now have two children. Linda’s father developed dementia later on and was given a robot pet as a companion. She saw how much having a robot pet friend helped her father, which is what led her to create this website and advocate to spread word about robot pets and how they can help both children and the elderly.
