Trigger-A3 Data Center
The TRIGGER-A3 is a versatile indoor and outdoor chassis using a tri-omni wheel structure. The triangular design allows for omnidirectional movement while achieving a minimal turning radius. Enlarged omni wheels enable movement in outdoor non-off-road scenarios. The non-recessed suspension supports a high center of gravity for attachments, balancing compactness and stability.
This chassis is particularly suitable for indoor and outdoor navigation, maneuvering in tight spaces, and turning. It can carry a robotic arm and serve as a base for semi-humanoid robots.
Trigger-A3 integrates an IMU for odometry fusion, achieving high precision in dead reckoning. Odom vs. motion capture comparison video:
