Choosing motors, power sources and cosmetics

When it comes to motors, power sources, and cosmetics, there are a few things to consider when building a Chuck E. Cheese animatronic.

Motors

Servos are a popular choice for powering animatronics, offering precise control over the movement of the character. They are relatively inexpensive and well suited for smaller applications, but they can be more difficult to program. Pneumatic cylinders are another option and are often used for larger-scale projects. They are easy to program and offer a wide range of movement, but they can be more costly. Push/pull solenoids are a middle ground between servos and pneumatics, offering similar functionality to pneumatics but on a smaller scale.

Power Sources

The power source you choose will depend on the type of motor you select. Servos can be powered by an Arduino, a popular microcontroller that is versatile and relatively inexpensive. Pneumatic cylinders, on the other hand, require an air supply and valve bank to function. Solenoids can also be controlled using an Arduino, and the same setup can be easily modified for use with pneumatics.

Cosmetics

The cosmetic design of your animatronic will depend on the character you are creating. For a Chuck E. Cheese animatronic, you will need to create a mouse-like character with a friendly and cute appearance. Consider using materials like cardboard, foam, felt, and paper mache to create the body and clothing of the character. Focus on making the character visually appealing and distinct from other mouse characters, such as Mickey Mouse.

When building a Chuck E. Cheese animatronic, it is important to consider the balance between cost, complexity, and the desired level of movement and functionality. The choice of motors, power sources, and cosmetics will depend on your specific requirements and budget. It is recommended to weigh the pros and cons of each option and plan accordingly.

Using servos and cardboard

To build a Chuck E Cheese animatronic, servos and cardboard can be used for a lot of the construction. First, you will need to draw out your design, label all the parts and their movements, and create blueprints for your parts.

Servos are simple to program with an Arduino, but they won't last long. They are also cheaper and more complex to program than pneumatics, which are more practical for larger applications. For something like Chuck E Cheese, pneumatics or solenoids are recommended.

Cardboard can be used for the structure of the animatronic, and paper mache can be used for the mask. Foam and felt can be used for the fur and clothes.

The Arduino can be used to power the servos, and a program like Visual Show Automation can be used to control the animatronic's movements.

Creating a blueprint

To create a blueprint for a Chuck E. Cheese animatronic, you'll need to consider the following steps and factors:

Step 1: Define the Purpose and Scope

Start by defining the purpose of your animatronic figure. Is it intended for entertainment, education, or something else? Chuck E. Cheese animatronics are primarily used for entertainment, so you'll want to focus on creating a fun and engaging experience for your audience.

Step 2: Choose the Type of Animatronic

Decide on the type of animatronic you want to create. Will it be a full-body animatronic or a waist-up version? Chuck E. Cheese animatronics have varied over time, with some being full-bodied while others are half-bodied or portrait versions.

Step 3: Determine the Movements

Determine the range of movements you want your animatronic to perform. Will it have simple movements like moving its arms up and down, or more complex ones? The number and complexity of movements will impact the design and choice of components. The first-generation Chuck E. Cheese animatronic had basic movements, including arm movement, side-to-side motion, blinking, and jaw movement. Later versions had more advanced functions, with the Garner Holt Productions version having 32 independent functions.

Step 4: Select the Materials

Choose the materials you will use to build your animatronic. This includes the frame, covering, and any cosmetic enhancements. Cardboard, wood, metal, foam, and felt can all be used, depending on your budget and the desired level of detail. For example, a paper mache mask and foam and felt for the fur and clothes were used in one instance.

Step 5: Decide on the Power Source

Determine how you will power your animatronic. This could be through motors, servos, or even pneumatic cylinders. Servos are typically used for smaller applications and are more affordable but harder to program. Pneumatic cylinders are more expensive but are easier to program and are suitable for larger-scale projects. The choice of power source will impact the overall design and complexity of your animatronic.

Step 6: Create a Detailed Design

Draw out your design, labelling all the parts and their corresponding movements. This will help you visualise how the different components will work together. You can also create a 3D model or maquette to better understand the proportions and overall appearance of your animatronic.

Step 7: Finalise the Blueprint

Once you have a clear idea of the movements, materials, and power source, finalise your blueprint. This should include detailed diagrams and specifications for each component, as well as any necessary programming or control systems. Consider the manufacturing process and create an assembly line-style approach to streamline production, especially if you plan to create multiple units.

Remember to refer to existing Chuck E. Cheese animatronics for inspiration and to understand the evolution of their designs over time.

Using pneumatics or solenoids

Pneumatics and solenoids are a great way to bring your animatronic Chuck E. Cheese character to life. Here's a detailed guide on using these components to create captivating movements and expressions.

Choosing Pneumatics or Solenoids

Pneumatics and solenoids offer distinct advantages for animatronics. Pneumatic systems use compressed air to drive movement, while solenoids employ electromagnets. Pneumatics are ideal for larger-scale projects, providing strong and precise motion. In contrast, solenoids are smaller and more compact, making them suitable for applications where space is limited. Consider your animatronic's size and the range of motion you want to achieve when selecting between the two.

Sourcing Parts and Materials

When using pneumatics, you'll need a pneumatic cylinder, fittings, a solenoid valve, air tubing, and a compressor. Pneumatic cylinders are typically plungers with two movements: in and out. To achieve more complex movements, you can use flow control to adjust the speed without reducing compressor pressure. Solenoids, on the other hand, use electro magnets to control the flow of air. While you can find affordable solenoids online, be cautious about their quality to avoid leaks and relay issues.

Mounting Considerations

Mounting your pneumatic or solenoid components securely is crucial. For pneumatic cylinders, finding the right mounting point for each joint is essential. Improper mounting can lead to binding and damage to the cylinder seal, resulting in air leaks and impaired movement over time. One effective method is to screw the pneumatic cylinder to a flexible strip of aluminum attached to the joint, allowing for some adjustable flex during actuation.

Programming and Control

To achieve dynamic and lifelike movements, programming and control systems are key. You can use an Arduino or similar microcontroller to send electrical signals to your solenoids, controlling the flow of air and, thus, the animatronic's movements. For more complex routines, consider using software like Vixen Lights, which allows you to program movements to music and lights. This can add a captivating dimension to your animatronic's performance.

Cosmetic Enhancements

While not necessary for small-scale projects, cosmetics play a crucial role in larger animatronics. Latex masks, for instance, can be painted and fitted to your character, creating a seamless and expressive mouth. Additionally, consider using body shells and head shells made from materials like PVC piping to shape the body under the costume, giving your animatronic a polished and professional look.

Tips for Success

When building your animatronic Chuck E. Cheese, remember to focus on realistic movements, especially when programming speech or singing. Aim for subtle mouth movements to avoid a jittery appearance. Additionally, create a diagnostics program to monitor your animatronic's movements and adjust flow control as needed. Finally, don't be discouraged by setbacks—building animatronics is a complex process, and perseverance will lead to impressive results.
