QianEasy’s Smart Wheelchair Control is built for full autonomy: the chair plans a route, navigates indoor spaces, and avoids dynamic obstacles — powered by 3D sensing and closed-loop motion control. The story is the platform’s intelligence, not a lab demo with a person at a workstation.

Autonomous wheelchair sensor suite — Multi-sensor stack for auto navigation, planning, and avoidance.

Autonomy stack

We treat the wheelchair as a specialized autonomous mobile platform: map / localize, plan globally, replan locally, and execute smooth, safe trajectories under real corridor constraints.

Core capabilities

Auto navigation — localize and drive toward destinations in mapped indoor spaces
Auto path planning — global routes plus local replanning around people and clutter
Auto obstacle avoidance — real-time 3D perception with soft braking and clearance keeping
Closed-loop control — comfort-tuned accel / turn profiles with safety watchdogs

Fully autonomous smart wheelchair — Product-first: an autonomous wheelchair navigating a real indoor corridor.

Technology highlights

Perception	TOF / array LiDAR / camera fusion for geometry and free space
Planning	Global path + local dynamic replanning
Control	Closed-loop drive with speed / torque limits
Safety	Watchdogs, e-stop path, fail-safe stop on sensor loss
Integration	Powered wheelchair / mobility base with drive interface
