Trigger-A3

中文 | English

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:

Safety Instructions

Important Safety Information

  • It is strictly prohibited to use the device during charging.
  • Confirm the device's operating voltage, power, and installation parameters before use. Issues caused by exceeding these parameters are not covered under warranty.
  • Assess the IP rating, temperature, and suitability of the environment. Issues arising from harsh conditions are not covered under warranty.
  • This device does not provide collision, fall, or proximity warnings. Conduct safety evaluations for integrated products and ensure compliance with relevant regulations and certifications to avoid major safety hazards.
  • Read maintenance requirements to prevent irreversible damage from incorrect operations, such as battery over-discharge, low tire pressure causing hub damage, or lack of lubrication leading to axle wear.
  • For first-time use, place the device in a safe, open area without loads. Follow the operation instructions and test all functions. Contact customer service if issues arise.
  • In case of abnormalities or accidents, use the emergency stop or power off immediately to prevent further damage. Contact technical support and do not disassemble the device yourself. Note: Damage from unauthorized disassembly, modification, misuse, or force majeure events is not covered under warranty. The product is not liable for safety incidents with user-integrated devices. Users must conduct risk and reliability assessments.

Charger Usage Instructions

  • Lithium battery chargers provide different voltages depending on the number of cells: common specifications are 7 cells (29V), 6 cells (25V), and industry-standard 13 cells (54V). Choose the correct charger, preferably the one provided with the device. Contact customer service if needed.
  • Check that the charging voltage is correct; it is indicated on the device's nameplate.
  • Ensure charging is supervised; disconnect power when unattended.
  • Start charging after device alignment, and do not use the device while charging.
  • Keep the charger and device away from bedrooms, flammable materials, and ensure they remain dry.
  • The charger uses a 220V AC power input; ensure stable input voltage.
  • Do not exceed 8 hours of continuous charging. Stop immediately if the charger overheats.
