Overview
CubeMars Driver Board V3.0 is a third-generation brushless motor controller integrated into the AK V3.0 series. It can be connected to a PC using the RUBIK LINK V3.0 interface tool for motor control, tuning, and firmware upgrades via CubeMars Tool V3.0 software. The drive board supports Servo mode and MIT mode, providing single-loop control for velocity, current, torque, brake, and position, as well as multi-loop control such as position-velocity loop control.
Key Features
- Supports Servo mode and MIT mode
- PC connection for tuning and firmware upgrades (RUBIK LINK V3.0 + CubeMars Tool V3.0)
- CAN communication: 1Mbps
- Available in two board sizes: Small Size and Big Size
- Board interfaces/structure identifiers: three-phase wires connection port, hardware version, connection port, mounting holes
Applications
- Humanoid robots
- Robotic arms
- Exoskeletons
- Quadruped robots
- AGV vehicles
- ARU robots
