Neurostar Drill and Injection Robot
Fully automated stereotaxic platform from Neurostar that combines computer-controlled cranial drilling with ultraprecise viral / drug injection — no tool exchange, no recalibration between drilling and injection. Autostop Drilling electrically detects skull penetration and halts movement instantly, protecting the brain. Atlas integration, automatic skull-tilt correction and stored protocols turn high-precision stereotaxic surgery into a reproducible, technician-friendly workflow.
What is the Neurostar Drill and Injection Robot?
The Drill & Microinjection Robot from Neurostar is a fully automated stereotaxic platform that combines computer-controlled cranial drilling and ultraprecise viral / drug injection in a single, uninterrupted workflow — no tool exchange, no recalibration between drilling and injection, and no tool exchange between subjects. Atlas integration, automatic head alignment, and submicron-precision motor control turn a multi-hour manual stereotaxic procedure into a reproducible, technician-friendly task.
The system’s headline upgrade is Autostop Drilling: an integrated electrical-impedance circuit detects the exact moment the drill bit penetrates the skull and immediately halts both rotation and DV advancement — protecting the underlying brain tissue from any over-penetration. Combined with stored protocol playback, the robot enables genuinely high-throughput multi-animal cohorts at AAV-level precision.
Key Features
- Computer-controlled stereotaxic frame: Full software navigation of XYZ axes with atlas integration and stored target coordinates.
- Autostop Drilling: Electrical-impedance detection stops the drill the instant skull penetration is sensed — protects brain tissue from drill-bit damage.
- No tool exchange: Drill and injection are integrated into one workflow; load the syringe once and run successive animals without recalibration.
- Multisite injections: Pre-program multiple coordinates per animal and replay across the cohort.
- Atlas integration with size scaling: Software adapts the atlas to animal size and age, maintaining target precision across developmental stages.
- Alignment correction: Automatic skull-tilt correction — no manual leveling.
- Stored protocols: Define, save, and replay full experiments — reproducible targeting across operators and cohorts.
- Advanced drilling modes: Supports skull thinning, brain windowing, and contour drilling.

Why automated stereotaxic surgery matters
Stereotaxic AAV / viral-vector injection is one of the most reproducibility-critical procedures in modern neuroscience. Manual stereotaxic surgery introduces inter-operator variability at every step — bregma localization, skull leveling, drill depth, injection rate. The compound effect is the well-documented variability in viral expression locations across cohort animals, even within the same lab.
The Neurostar Drill and Injection Robot eliminates the human-error component at each of these steps. Bregma is localized by camera, skull tilt is auto-corrected, drilling is electrically gated to stop at penetration, and injection coordinates / rates are software-defined. The result is dramatically reduced inter-animal variability — a meaningful step toward the 3Rs principle of reduction, since fewer animals are needed to power the same statistical comparison.
Typical Use Cases
- AAV / viral vector stereotaxic injection across large cohorts (optogenetics, chemogenetics, calcium-imaging tracers).
- Multi-site neural-circuit injections in a single animal.
- High-throughput pharmacology and toxicology stereotaxic studies.
- Cranial window creation with automatic breakthrough detection.
- Teaching programs training new stereotaxic surgeons — reproducible technique on day one.
