How to Build a Robot: 5 Things You Need to Get Started

Building a robot might seem like some far-off futuristic challenge, impossible in today’s day and age, but with the right tools, components, and knowledge, it’s actually an achievable goal! Whether you’re designing a robotic arm, a mobile bot, or an autonomous system, every great machine starts with a strong, yet simple, foundation. In this guide, we’ll walk you through how to build a robot and the five things you need to get started, focusing on everything from the control system to robotics wires that will put your ideas in motion. 

How to Build a Robot: 5 Things You Need to Get Started

If you want to bring a robot to life, you’ll have to start with these five basics: a control system, actuators, sensors, a chassis, and some reliable wiring. Each one plays a key role in how your robot functions, moves, and interacts with what is around it. You can picture it this way: the control system is the brain, the actuators are the muscles, the sensors are the senses, the chassis is the skeleton, and the wiring is the nerves tying everything together. 

Ignoring or missing out on even one of these elements or using subpar materials can cause major setbacks. That’s why it’s so important to know how each component works, work with each other, and make informed choices about what you use. 

A Reliable Control System

Every robot needs a brain. Whether you’re working with a microcontroller like Arduino, a Raspberry Pi, or a more advanced onboard computer, your control system processes sensor data and issues commands to motors and other hardware. 

You’ll need to pick out a control system that matches both the complexity and processing needs of your personal project. For simple jobs, you can probably get away with a microcontroller. If you’re looking to create more complex behaviors like vision processing or AI decision-making, you’ll need greater computational power and memory. 

Actuators and Motors Make Things Move

Once your robot has the brain (i.e., the control system), it needs the muscles. Actuators, like servo motors, stepper motors, or linear actuators, convert electrical energy into movement. The type of actuator you’ll choose depends on the kind of movement you want, from rotating joints or wheels to lifting arms and sliding parts. 

These components must match your robot’s weight, power system, and control design. But more importantly, they need reliable connectivity—motor wires must tolerate motion, tension, and often harsh environments. That’s why robotics wire from Calmont is designed for dynamic flexing and high-performance reliability, ensuring your actuators move the way they should, every time.

Sensors for Interaction and Awareness

Sensors give your robot the ability to see, hear, feel, and respond to the world around it. From infrared detectors and ultrasonic rangefinders to gyroscopes and cameras, sensors provide the feedback loop needed by your control system to make decisions. 

Sensor data must travel quickly and cleanly to function properly. That requires cables that can shield against noise, fit in compact spaces, and maintain integrity even under constant movement. This is where custom wire and cables make all the difference.

Durable, High-quality Wiring

Without wiring, nothing works. It’s the quiet hero of every robotics project—and often the first place things go wrong. Standard wires can’t handle the demands of moving parts, tight tolerances, and data integrity. That’s why sourcing the right robotics wire is vital to your robot’s performance.

Calmont specializes in high-flex, high-performance cable solutions engineered specifically for robotics. From ultra-flexible multi-conductor wire to shielded cables that eliminate signal interference, our custom wire and cables can survive where standard wire fails. The result? A robot that’s not only functional but also reliable for the long haul.

A Chassis to Hold It All Together

Your robot needs a frame, aka a chassis, to support and house all the components. Depending on your goals, this might be a metal skeleton for strength, a 3D-printed body for versatility, or a modular kit for prototyping.

Designing a good chassis isn’t just about strength or aesthetics. It also needs the right space and layout. You need to route cables efficiently, avoid tension or bending, and minimize interference. Using custom cable assemblies enables you to optimize the interior space of your robot while minimizing failure points and reducing cable clutter.

What Are the Best Materials To Use in Your Robotics?

Robotics is a field of study that is constantly evolving. Its technicians include mechanical engineers, electrical engineers, and computer scientists, who continue to make major scientific leaps in the field. The industry is characterized by the design, construction, and operation of robots. Construction, in this case, includes the computer systems for the robot that provide control and feedback. With such a complex focus, it is important to know what the best materials to use in your robotics are. Consider the following information about robotics materials to use for your next project.

What Are the Best Materials To Use in Your Robotics?

Robots are becoming increasingly popular in a wide variety of industries. They make many tasks more accessible and efficient, which can save individuals and companies time and money. Robotics engineers use several types of materials because of the variety of industries that use robotics. Consider the following materials and their respective benefits when used in the field of robotics.

Plastic Materials

Several different types of plastics are used in robotics, including polycarbonate, polyvinyl chloride (“PVC”), and acrylonitrile butadiene styrene (“ABS”). Robotics engineers use plastics because they are flexible and lightweight, which is especially beneficial for robotics in the healthcare field. Wires and cables often need to be easily moved, and plastic is ideal for this function because it can be molded into various shapes when creating robotic parts.

Composite Materials

Composite materials are made up of two or more substances that are combined to create a new material with unique properties. Common composites used in robotics include carbon fiber, kevlar, and fiberglass. These materials are lightweight but also highly durable and strong. Industries that use composite materials for robotics include aerospace, automotive, and healthcare.

Metal Materials

Metals are the most common materials used in robotics. They offer several benefits in the field, including strength, durability, and longevity. The common types include aluminum, steel, and titanium. Automotive robotics and aerospace engineers often use these metals. The benefits associated with metal are unparalleled. They do not require replacement as often as other materials and can withstand diverse environments.

Elastomer Materials

Robotics engineers often use rubber and elastomer materials. They offer several benefits that are unlike alternative materials. Rubber and elastomers are flexible and can return to their original shape, which is highly beneficial in the automotive industry. Common materials include silicone rubber, polyurethane, and neoprene, which are highly durable and can withstand significant wear and tear.

Soft Materials

The field of robotics is rapidly changing and evolving. In fact, there is a new area of robotics referred to as “soft robotics.” This area focuses on flexible robots that can easily bend, stretch, and twist. Those in healthcare, agriculture, and marine biology most commonly utilize this category of robotics. Common materials used in this industry include hydrogels, silicone elastomers, and shape memory alloys.
