Motor Function
Passive Running Wheel Data Acquisition System (BA-RW01): head fixed above the wheel with voluntary limb stepping — optical-encoder capture of displacement, speed, and direction. Open, unobstructed design for video and multimodal sync with electrophysiology, optogenetics, and eye tracking.
HARDWARE & SOFTWARE
Hardware platform and host software as one delivery — from wheel stepping and head fixation to live curves and TXT export, with an optional suite for fixed eye-tracking combo use.
Hardware
External-stepping unobstructed wheel + core animal fixation module + high-res optical encoder (ESP32 coupled). Supports cameras, reward/stimulus add-ons, and event-sync I/O.
Software
Solo mode focuses on live wheel kinematics and curves; with fixed eye tracking, a unified DAQ and cross-modal suite delivers publication-ready charts.
CAPABILITIES
Closed traditional wheels are scene-limited and occluding — poor fit for head-fixed implants. The passive design unites stable head fixation with high-precision stepping for multimodal neuroscience.
Mice step above the wheel with full-body video access — easy to add cameras, sensors, and behavior devices for synced behavioral and physiological data.
Stable fixation for electrode/fiber-implanted mice — meets stability and reproducibility needs for electrophysiology and opto/chemogenetics.
Add reward/stimulus modules for flexible interventions — replaceable parts for different models and customized designs.
MOTION CAPTURE
High-res optical sensing of wheel rotation — live conversion to core kinematics with dynamic host visualization.
Anterior–posterior displacement over time — wheel position evolution.
Cumulative and session distance — activity and endurance.
Live speed curves capture acceleration, slowing, and rate fluctuations.
Wheel rotation direction — preference and switching.
Effective movement duration for activity rhythm and bout structure.
Raw signals, computed metrics, and timestamps in standard TXT — manual download for secondary analysis.
SOFTWARE & MODULES
Two software tiers — from basic motor-function testing to advanced multimodal fusion.
Default for standalone wheel use: serial encoder DAQ for displacement, distance, speed, time, and direction; live displacement–time and speed–time curves; event-sync box for external triggers.
Enabled with fixed eye tracking: unified DAQ for wheel motion, eye video, and event marks; fuse pupil/gaze with speed/distance on one timeline for motor–cognition studies and publication-ready reports.
Explore fixed eye trackingPairs with fixed eye tracking — swap the interaction module for this wheel to quantify voluntary locomotion speed during eye assays.
Go to eye-tracking pageMulti-channel I/O for external triggers and control outputs — precise marks for optogenetic stimulation, injections, and more.
WORKFLOW
A standard path from platform setup to export — complete, reviewable acquisition end to end.
Integrate wheel, fixation, and control box — add camera or sync I/O as needed.
Seat the head-plate mouse and fine-tune the 5-axis mount.
DAQ software records trajectory, distance, speed, and more — curves refresh live.
Auto-process displacement/speed charts; all records land in standard TXT for download and deeper analysis.
APPLICATIONS
A motor-function platform usable while recording neural signals — for neuroscience, pharmacology, and behavior.
Quantify wheel locomotion under head fixation for disease mechanisms and drug intervention assessment.
Sync locomotion with neural or optical intervention signals on one platform — comparable across paradigms.
With fixed eye tracking, link pupil/gaze to wheel speed/distance for cognition–motor interaction.
Add reward/stimulus devices to compare locomotion outputs under different intervention conditions.
