Scalar TPU Chassis — Core Antweight Structure
The Scalar TPU Chassis is the 3D-printed core structure for the Repeat Robotics Scalar Antweight Combat Robot. Designed to house internal components — including electronics, battery, and drive system — this chassis tub provides a durable, impact-resilient foundation that works in conjunction with the rigid carbon fiber frame plates used in the Scalar Frame Kit.
Printed from tough TPU material, the chassis offers controlled flex and energy absorption, helping protect internal components during heavy impacts and drops. It serves as the structural backbone of the robot, with flexibility that works together with the rigidity of the top and bottom carbon fiber plates to create a balanced, combat-ready system.
This chassis is ideal for builders who want a reliable, easy-to-assemble structural core that accommodates standard antweight components and integrates seamlessly with the Scalar ecosystem.
Engineered for Combat-Ready Builds
- Durable TPU construction: Provides controlled flexibility and impact resistance.
- Internal component support: Designed to secure electronics, battery, and drive layout, with built-in motor impact isolation and support.
- Motor covers included: Kit includes 2× TPU motor covers to secure and protect the drive motors within the chassis.
- Seamless integration: Works directly with Scalar Frame Kit top and bottom plates.
- Easy assembly: Open access for wiring and component placement.
This chassis is ideal for Scalar builders completing a full robot or replacing a damaged TPU tub after hard hits. The Scalar TPU Chassis balances toughness, accessibility, and integration within the broader Scalar platform.

Frequently Asked Questions
What’s included with the Scalar TPU Chassis?
The kit includes 1× 3D printed TPU chassis tub and 2× TPU motor covers. The motor covers secure and protect the drive motors within the chassis during assembly and combat. Frame plates, hardware, and electronics are sold separately.
What is the Scalar TPU Chassis used for?
The Scalar TPU Chassis is the core structural tub for the Repeat Robotics Scalar Antweight Combat Robot. It houses internal components such as electronics, battery, and drive hardware while providing impact absorption during combat.
Is this chassis compatible with the Scalar Frame Kit?
Yes. The TPU chassis is designed to integrate directly with the Scalar carbon fiber top and bottom frame plates used in the Scalar Frame Kit.
Why is the chassis made from TPU instead of a rigid plastic?
TPU provides controlled flexibility that helps absorb impacts and reduce shock loads transmitted to internal components. This flexibility works together with the rigid carbon fiber plates to create a balanced, combat-ready structure.
Does this product include mounting hardware?
No. The Scalar TPU Chassis is sold as the chassis tub and motor covers only. Mounting hardware and frame plates are sold separately — see the Scalar Frame Kit.
Is this a replacement part or for new builds?
Both. This chassis can be used to replace a damaged TPU tub after combat or as the structural foundation for a new Scalar build. You can also use the chassis in your own design if you choose.
Is this chassis specific to antweight robots?
Yes. This chassis is designed specifically for the Scalar Antweight (US 1lb) Combat Robot platform.
