Modular XRP Body

Description:

During our FTC (FIRST Tech Challenge) outreach events, we identified an opportunity to enhance the experience for participating kids. Beyond simply driving and programming the XRP robots, we realized that offering them the chance to build with XRP would mirror the real-world processes many teams undergo throughout the FIRST season.

Through our observations, we noticed that some kids struggled with basic tools like screwdrivers, especially when we used to work with T-Prime robots. We also discovered that the kids were far more engaged when they could customize their robots.

This insight drove the design of the new XRP body. We focused on creating a modular design where every part could be assembled without any hardware—no screws, no tools. Instead, the parts slide or snap together, making the build process accessible and fun for everyone.

Additionally, we introduced channels and grooves on the original XRP body, inspired by the creative adaptations we've seen in the community. These features allow for easy integration of custom add-ons, enabling even more personalization. This approach not only makes the assembly process more enjoyable but also encourages creativity and hands-on learning, reinforcing the core values of the FIRST program.

The entire design includes multiple large flat edges, allowing kids to attach stickers or make doodles using Sharpies. If the parts become too cluttered with stickers or drawings, they can easily reprint just the part they need. The robot is divided into different parts, so you can print multiple copies of the same part using different colored filament, giving kids even more options for customization.

Instructions:

1. Take the motor holders and attach the motors to them, then attach the wheels to the motors, similar to the original XRP design.
2. Slide the motor holders onto the bottom of the body, aligning them with the grooves.
3. Attach the motor holder clips to prevent the motor holders from accidentally sliding off.
4. Slide the battery pack holder with the ball caster onto the body, inserting it from top to bottom.
5. Slide the front ball caster onto the body, also from top to bottom.
6. Place the battery pack into the designated slot on the holder.
7. Attach the motherboard on top of the body.
8. Attach the balls into the ball casters in the front and back.
