Technical Architecture
A deeper look into Helixa's system design, control logic, and safety architecture.
System Architecture Overview
Helixa is architected as a modular, layered system that separates concerns across three primary functional domains. This separation enables independent development, testing, and optimization of each subsystem while maintaining tight integration through well-defined interfaces and data contracts.
The architecture follows a sense-plan-act paradigm common in autonomous systems, with each layer operating at different temporal and spatial resolutions. Data flows unidirectionally from sensors through processing pipelines to actuators, with feedback loops at multiple hierarchical levels ensuring robust closed-loop control.
Three-Layer Architecture
Perception Layer

Bidirectional Data Flow
Operator Interface

Core Subsystems
Computer Vision System
Real-time 3D reconstruction and feature extraction
Hardware Components
- Dual 1920×1080 CMOS cameras with global shutter
- Synchronized capture at 60 fps with hardware triggering
- Calibrated stereo baseline of 120mm for optimal depth range
- Structured LED lighting for consistent illumination
Processing Pipeline
- GPU-accelerated image preprocessing and rectification
- Semi-global block matching for dense depth maps
- Point cloud generation with outlier filtering
- Feature extraction for texture and geometry analysis
Data Flow
Raw image data flows from cameras through a dedicated image processing unit where distortion correction, stereo rectification, and disparity computation occur. The resulting depth maps are fused with encoder data to produce accurate 3D point clouds in the robot's coordinate frame. These point clouds are then segmented and analyzed to extract relevant features such as surface normals, curvature, and texture characteristics. This processed geometric information is passed to the decision layer at 60 Hz with typical end-to-end latency under 50ms.
Precision Mechanical System
High-accuracy motion control and force regulation
Mechanical Design
- 6-DOF articulated arm with 400×400×300mm workspace
- Precision ball screw drives with anti-backlash nuts
- High-stiffness aluminum frame with vibration damping
- Quick-change tool interface for multiple end effectors
Actuation & Sensing
- Brushless DC servo motors with 0.1° resolution encoders
- 6-axis force/torque sensor at tool interface (0.01N resolution)
- Absolute position encoders for power-cycle recovery
- Temperature sensors for thermal compensation
Data Flow
Position encoder data is sampled at 1 kHz and fed into forward kinematics calculations to determine end-effector pose. Force sensor measurements are simultaneously acquired and filtered to remove high-frequency noise. These measurements are combined with vision-derived position estimates in an Extended Kalman Filter to produce optimal state estimates. The decision layer uses these estimates to compute desired trajectories, which are then converted to joint-space commands via inverse kinematics. Motor controllers execute these commands using cascaded position-velocity-current control loops running at 1 kHz.
Adaptive Control System
Real-time parameter adjustment and learning
Control Architecture
- Hierarchical control with three temporal layers (10/100/1000 Hz)
- Model-based feedforward with feedback compensation
- Adaptive gain scheduling based on operating conditions
- Disturbance observer for external force rejection
Learning Mechanisms
- Online parameter estimation for system identification
- Iterative learning control for repeated task improvement
- Experience database for similar-condition retrieval
- Operator feedback integration for preference learning
Data Flow
The adaptive control system receives state estimates from the perception layer and desired trajectories from the planning layer. It computes control errors and evaluates performance metrics in real-time. When operating conditions change (detected through sensor data analysis), the system adjusts control parameters to maintain optimal performance. Historical performance data is logged and analyzed offline to identify systematic patterns. These patterns inform updates to the control models and parameter lookup tables, which are deployed in subsequent operations. This creates a continuous improvement loop where system performance gradually improves with accumulated experience.

Safety Architecture
Safety is implemented through multiple independent layers, each providing protection against different failure modes. This defense-in-depth approach ensures that no single point of failure can result in unsafe operation. Each layer operates independently and can trigger protective actions without requiring coordination with other layers.
Layer 1: Hardware Safety
Independent hardware watchdog circuit monitors system heartbeat and can trigger emergency stop through dedicated safety-rated relays. This layer operates completely independently of software and provides protection against processor failures, software crashes, or communication loss.
Redundant Sensing
- • Dual position encoders with cross-checking
- • Redundant force sensors with voting logic
- • Independent limit switches at workspace boundaries
Force Limits
- • Mechanical force limiters prevent excessive loads
- • Current limiters protect motors from overload
- • Thermal cutoffs prevent component overheating
Layer 2: Real-Time Monitoring
Continuous evaluation of sensor data against safety envelopes at 1000 Hz. Position limits, velocity constraints, and force thresholds are enforced in real-time. Any violation triggers immediate motion cessation and operator alert with detailed diagnostic information.
Monitored Parameters
Layer 3: Predictive Safety
Forward simulation predicts system behavior over the next 100ms using current state and planned trajectory. If predicted trajectory violates safety constraints, motion is modified or halted preemptively. This reduces reliance on reactive safety measures and provides smoother, more predictable behavior.
Prediction Horizon
The system maintains a rolling 100ms prediction window, updated at 100 Hz. This provides sufficient time to decelerate safely while maintaining responsive control. Prediction accuracy is continuously validated against actual outcomes to detect model errors.
Layer 4: Operator Override Hierarchy
Human operator maintains supervisory control with ability to pause, adjust, or override system at any time. Emergency stop buttons provide immediate physical intervention capability. Operator commands take precedence over autonomous operation while respecting fundamental safety constraints.
Emergency Stop Logic
- • Immediate power cutoff to all actuators
- • State preservation for safe restart
- • Diagnostic logging of pre-stop conditions
- • Requires manual reset and safety checklist
Override Hierarchy
- • Emergency stop: Highest priority, immediate action
- • Pause: Controlled deceleration, state preserved
- • Parameter adjustment: Real-time tuning
- • Mode selection: Switch between operation modes
Safety Validation & Testing
The safety architecture undergoes rigorous testing including fault injection, boundary condition testing, and long-duration stress testing. Each safety layer is validated independently and in combination to ensure no single point of failure can compromise safety. Testing protocols include:
Fault Injection
Simulated sensor failures, communication loss, and processor faults to verify protective responses
Boundary Testing
Operation at and beyond safety limits to verify constraint enforcement and graceful degradation
Stress Testing
Extended operation under worst-case conditions to identify latent failure modes
