With the All Japan Robot Sumo Tournament (AJRST) opening the 500g category to international competitors in 2024, the race to build the ultimate mini-sumo robot has intensified. While many compact robot kits are designed for autonomous operation, converting them for Radio Control (RC) use has traditionally required additional hardware, complex wiring, and custom programming.
Inspired by the proven design of the MDDRC10, the MDDRC5 delivers the same ease of integration and reliable motor control in a significantly smaller size. Designed for applications that demand high-current performance within strict size constraints, the MDDRC5 is well suited for 500g RC sumo robots, compact mobile platforms, and other space-limited robotics projects.
Why Choose MDDRC5?
- Plug-and-Play Simplicity: Skip the messy breadboards and complex Arduino coding. Connect your RC receiver directly to the MDDRC5 and start driving in seconds. Perfect for getting your robot battle-ready fast.
- Compact Size: Ideal for compact competition robots. In the 500g category, every millimetre and gram counts. With a footprint of 69×35.5mm, the MDDRC5 is significantly more compact than the MDDRC10, freeing up critical space for extra weights to dominate the Dohyo.
- High-Current Performance: Don’t let the size fool you. With 5A continuous and a massive 20A peak current per channel, this driver is built to handle high-current demands, aggressive acceleration and sudden direction changes during intense head-to-head combat.
- Precision Control & Alignment: Unlike basic drivers, the MDDRC5 features a Motor Alignment Potentiometer. Fine-tune your motors’ alignment to ensure your robot drives dead-straight, giving you superior accuracy during a charge.
- Future-Proof for Pros: Start as a beginner with RC PWM, then grow into a pro. The USB-C port allows you to update firmware or upload custom code, transforming the board into a fully programmable controller as your skills evolve.
