Maver-L4
Inspired by the open-source TidyBot++ design
The Maver-L4 is a open source four-wheel steering omnidirectional mobile chassis. This chassis uses the PCW-25 module, with a built-in IMU and attitude fusion module, enabling precise trajectory tracking. It adopts a aluminum frame structure, supporting custom size and removable battery design for easy replacement, designed for early development and prototype verification scenarios.
Maver-L4 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.
