[Research and Development Transport Robot / AGV] Achieves a load capacity of approximately 40kg, a two-wheeled drive cart robot with a quiet structure using in-wheel motors.
The "Megalover Ver.3.0" is the successor to the research and development cart robot "Megalover Ver.2.1." It inherits numerous features such as a large chassis with a load capacity of approximately 40 kg, an aluminum chassis that is easy to modify and customize, compatibility with Arduino IDE for easier software development, and ROS1 support for flexible and advanced control. Additionally, by adopting a direct drive type in-wheel motor for the drive wheels, it achieves a significant noise reduction of about 20 dB compared to the previous model. While fully meeting the advanced functions and durability required in various automated transport and conveyance scenarios, it is also suitable for applications that demand high quietness, such as those involving voice recognition. ◆ ROS 2 compatible firmware has been released! 【Features】 ■ Quiet structure using in-wheel motors ■ Two-wheel drive cart robot with a load capacity of approximately 40 kg ■ Control possible via wired/wireless connection ■ Programmable with Arduino IDE ■ Easy to expand aluminum frame ■ Compatible with control via ROS1 and ROS2 ■ Standard equipped with an emergency stop switch, with adjustable installation position

In large research and development cart robots, the operational noise of the old model, Megarover Ver2.1, did not pose any special issues. However, when executing voice recognition or voice output with the equipment mounted on the cart robot, it is desirable for the operational noise to be as low as possible. Therefore, in the newly released Megarover Ver.3.0, we have adopted a new in-wheel motor for the drive wheels. As a result, compared to Megarover Ver2.1, our experimental data shows a noise reduction effect of approximately 20dB (within the audible range). The actual perceived operational noise can vary significantly depending on the operating environment, road conditions, load conditions, and operating program, but in our internal verification, we have achieved a level of quietness where "you wouldn't notice the Megarover Ver.3.0 approaching." *Please note that the same results may not be obtained under all operating conditions.

This product features a three-wheeled structure equipped with standard two-wheel drive wheels and a single caster. By adopting standard wheels, it ensures intuitive control ease and quiet operation, enabling specific research and development aimed at practical levels. The portable weight remains approximately 40 kg, unchanged from the previous model, and the maximum speed has been measured at 1.6 m/s. Research and development can be conducted with practical transportation applications in mind, unique to large autonomous control carts. *This product is not designed for passenger use.*

This product comes standard with an "emergency stop switch," which was previously an optional accessory in conventional models. Additionally, it is equipped with multiple pre-drilled holes for the emergency stop switch, allowing users to easily change the installation position after purchase. This enables the emergency stop switch to be placed in the optimal position according to the actual application, thereby enhancing safety during operation.
