Frequently Asked Questions
Get answers to common questions about this robot
Q1. How to troubleshoot RB-Y1?
Check system diagnostics via the onboard interface or SDK logs, verify sensor connections (IMU, LiDAR), ensure no self-collision alerts are active, and reboot if unresponsive. Consult error codes for specific issues.
Q2. How to set up RB-Y1?
Place RB-Y1 on a flat surface, connect power supply, establish Wi-Fi or Bluetooth connection, calibrate sensors through the SDK, and perform initial arm and wheel movement tests to confirm functionality.
Q3. What are RB-Y1's primary use-cases?
RB-Y1 is designed for industrial automation, complex manipulation tasks, AI research, teleoperation, and environments requiring agile mobile manipulation with dual arms and vertical torso adjustment.
Q4. How to operate RB-Y1?
Use the master-slave teaching mode or teleoperation via joystick, touchpad, or VR interface; control movement with omnidirectional Mecanum wheels; program tasks through the SDK or AI simulation environment.
Q5. How to maintain RB-Y1?
Regularly clean sensors and wheels, check mechanical joints for wear, update software, calibrate sensors periodically, and inspect power systems to ensure optimal performance and longevity.
Q6. What safety features does RB-Y1 have?
RB-Y1 includes self-collision prevention for arms, stable center-of-gravity control during movement, and emergency stop functions to ensure safe operation in dynamic environments.
Q7. How does RB-Y1 handle different surfaces?
Its omnidirectional Mecanum wheels provide smooth 360-degree movement on flat, indoor surfaces; vertical torso adjustment helps maintain balance on slight inclines or uneven floors.
Q8. How to clean RB-Y1?
Power off the robot, use a soft cloth to wipe the exterior and wheels, avoid moisture near electronic components, and gently clean sensors like LiDAR and cameras with appropriate lens wipes.
Q9. How does RB-Y1 navigate?
RB-Y1 uses omnidirectional Mecanum wheels for agile movement combined with sensor data from IMU and LiDAR, processed via its full-body 20-axis control system for precise positioning and obstacle avoidance.
Q10. What are common RB-Y1 problems?
Typical issues include sensor misalignment, communication dropouts over Wi-Fi/Bluetooth, joint calibration drift, and occasional software glitches requiring resets or updates.
Q11. How to reset RB-Y1?
Perform a soft reset via the control interface or SDK; if unresponsive, power cycle the robot by disconnecting and reconnecting the power supply to reboot all systems.
Q12. How to control RB-Y1?
Control RB-Y1 through master-slave teaching, teleoperation devices like joysticks or VR controllers, or programmatically via its SDK supporting motion commands and sensor integration.
Q13. How to connect RB-Y1 to Wi-Fi?
Access the robot’s network settings via the control panel or SDK, select the desired 2.4 GHz or 5 GHz Wi-Fi network, enter credentials, and confirm connection status before operation.
Q14. What is RB-Y1's warranty?
RB-Y1 typically comes with a one-year manufacturer warranty covering hardware defects and software support; extended service plans may be available through Rainbow Robotics.
Q15. How to update RB-Y1's software?
