About Robot Hardware & Expansion
Robot hardware forms the physical foundation of a robotic system, including controllers, actuators, sensors, power systems, communication interfaces, and structural components. Many robotics platforms are designed to be modular, allowing users to expand and customise their systems for specific applications.
Whether you're upgrading a mobile robot, adding sensors to a robotic arm, integrating AI computing hardware, or building a custom research platform, understanding hardware compatibility and expansion options is essential for successful robotics development.

Frequently Asked Questions
Most robots consist of a controller, actuators or motors, sensors, power systems,
communication interfaces, structural components, and software that coordinates all subsystems.
Many robotics platforms are designed to be expandable. Depending on the robot, you may be able
to add sensors, cameras, LiDAR systems, robotic arms, additional computing hardware,
communication modules, or upgraded batteries.
A controller typically manages low-level functions such as motor control and sensor inputs,
while an onboard computer handles higher-level tasks such as navigation, AI processing,
computer vision, and ROS applications.
Common robotics computing platforms include Raspberry Pi, NVIDIA Jetson, industrial PCs,
Intel NUC systems, ARM-based computers, and manufacturer-specific controllers.
Robots commonly use servo motors, brushed DC motors, brushless DC motors, stepper motors,
and linear actuators. The best choice depends on speed, torque, precision, and application requirements.
In many cases, yes. However, you must consider payload capacity, mounting options,
power requirements, communication interfaces, and software compatibility before integration.
Common interfaces include USB, Ethernet, CAN bus, UART, I2C, SPI, WiFi, Bluetooth,
and industrial communication protocols depending on the robot and application.
Check the communication interface, power requirements, mounting compatibility,
software support, available drivers, and whether the robot controller or computer
can support the additional device.
Lithium-ion and lithium-polymer batteries are commonly used due to their energy density
and rechargeability. Some industrial robots may also use lead-acid or specialised battery systems.
Many platforms support computer upgrades, particularly when moving from basic control
systems to AI-enabled computing platforms such as NVIDIA Jetson. Compatibility should
always be verified before upgrading.
Payload capacity refers to the maximum weight a robot can safely carry while maintaining
stable operation and expected performance. This includes sensors, manipulators,
computers, batteries, and other accessories.
Yes. RoboSavvy can help you identify compatible sensors, controllers, computing platforms,
robotic arms, communication systems, power solutions, and accessories for your robotics project.
