MechaZUMO Advanced Sumo Robot 1KG

MechaZUMO Advanced Sumo Robot 1KG is a competition-grade sumo robot developed by Mechabotics for high-performance robotic sumo applications. Built with a compact 150 ? 150 mm footprint and weighing approximately 0.95?1.0 kg, MechaZUMO combines high-speed drive, strong traction and a durable low-profile chassis for competitive performance on the Dohyo.

Powered by two 12V G25 high-speed DC motors rated at approximately 939 RPM and 3 kg?cm torque, the robot provides fast acceleration and aggressive movement. A 17A dual motor driver and dedicated controller board provide reliable motor control, while the 11.1V LiPo battery supplies the power required for competition.

The robot is equipped with four 0.4 mm ? 150 mm sharp blades, designed to achieve a low front clearance and improve the ability to get underneath an opponent during attack.

Its chassis combines 3D-printed components with CNC-machined metal parts, providing a balance between strength, weight and serviceability. High-grip silicone tyres provide traction on the Dohyo, with an additional pair of silicone tyres included as spare.

A built-in digital voltage display allows quick battery voltage monitoring, while the competition package also includes a storage box, charger and essential maintenance accessories.

Available Versions

MechaZUMO 1KG is available in three competition configurations:

Competition Spec ? Autonomous Version | KIT010

Designed for fully autonomous sumo competition.

The Autonomous Version is equipped with:

5 ? Diffuse Opponent Sensors with detection range up to approximately 80 cm

2 ? Edge Detection Line Sensors

7-Mode Tactical DIP Switch

Start Module + Remote

The opponent sensors allow the robot to detect competitors from multiple directions, while the edge sensors detect the Dohyo boundary and help prevent the robot from driving outside the competition area.

The 7-mode tactical system allows different strategies or starting movements to be selected before a match.

Competition Spec ? RC Version | KIT011

Designed for manually controlled RC sumo competition.

The RC Version includes:

1 ? 6-Channel DumboRC Controller

RC Receiver System

Manual directional and movement control

This configuration gives the operator direct control over the robot, making driving skill, positioning, timing and attack strategy important elements during competition.

Competition Spec ? Autonomous + RC Version | KIT012

The most versatile configuration in the MechaZUMO 1KG series.

This version combines the capabilities of both Autonomous and RC control in a single robot platform, making it suitable for users who participate in different competition formats or institutions requiring a flexible robotics training platform.

It combines the autonomous sensing and tactical system with the RC control system.
