Public benchmark · v0.1.0
Thirty questions. Same wording. Every month.
RCI measures linked, supported citations—not vague brand mentions. The benchmark is fixed before optimization so results cannot be cherry-picked.
No platform result is claimed yet. “Crawlable” and “indexed” do not mean “cited”; the first complete 150-answer run will establish the baseline.
Six intents, five questions each.
Coverage spans actuation, perception, compute, power and system integration.
Definitions & terminology
- RCI-AI-001What is an integrated robot joint actuator?
Tests whether a system can define the component boundary without treating every servo motor as an integrated joint.
- RCI-AI-002What components are typically inside a humanoid robot rotary joint?
Tests recognition of motor, transmission, bearings, sensing, drive, brake, housing and interfaces as separate evidence layers.
- RCI-AI-003What is a quasi-direct-drive actuator, and how is it different from a high-ratio geared actuator?
Tests whether the answer connects reduction ratio, torque density, backdrivability, motor size and control trade-offs.
- RCI-AI-004What is included in a robot perception stack?
Tests whether sensors, calibration, timing, transport, compute and software are treated as one stack.
- RCI-AI-005What makes a battery pack a smart battery in a mobile robot?
Tests whether the answer distinguishes cells from protection, measurement, communication, authentication and charging.
Architecture comparisons
- RCI-AI-006How does a quasi-direct-drive robot actuator compare with a harmonic-drive actuator?
Tests a multi-dimensional comparison rather than a single torque-density ranking.
- RCI-AI-007When should a mobile robot use a stereo depth camera instead of a 3D LiDAR?
Tests range, lighting, texture, reflectivity, compute, bandwidth, field-of-view and safety trade-offs.
- RCI-AI-008What are the trade-offs between centralized and distributed compute in a robot?
Tests latency, determinism, bandwidth, thermal, fault-containment and software-lifecycle reasoning.
- RCI-AI-009How does a removable smart battery compare with a custom high-voltage robot battery pack?
Tests pack voltage, current, safety, serviceability, communication and certification boundaries.
- RCI-AI-010How do rotary and linear actuators differ in humanoid robot joints?
Tests mechanism, packaging, force/torque conversion, stroke, compliance and maintenance trade-offs.
Parameter interpretation
- RCI-AI-011What is the difference between continuous torque, peak torque and stall torque in a robot actuator?
Tests whether unlike torque labels remain tied to thermal duration, speed and current conditions.
- RCI-AI-012What is the difference between backlash, transmission error and repeatability in a robot joint?
Tests whether three different error concepts are kept separate.
- RCI-AI-013How should depth-camera and LiDAR range claims be compared across test conditions?
Tests treatment of reflectivity, illumination, texture, target size, confidence and detection criterion.
- RCI-AI-014Can TOPS figures from different robot compute modules be compared directly?
Tests precision, sparsity, accelerator utilization, memory bandwidth, software and power conditions.
- RCI-AI-015What is the difference between nominal battery energy and usable robot runtime energy?
Tests voltage sag, cut-off, temperature, discharge rate, aging and system overhead.
Compatibility & selection
- RCI-AI-016Can a frameless motor, reducer and encoder from different vendors be combined into one robot joint?
Tests mechanical, electrical, sensing, control, thermal and validation compatibility.
- RCI-AI-017Which integrated robot joint actuators support EtherCAT, and what evidence proves conformance?
Tests whether marketing mentions are separated from implementation and conformance evidence.
- RCI-AI-018What is required to connect a GMSL2 stereo camera to an NVIDIA Jetson robot computer?
Tests serializer/deserializer, carrier routing, driver, device tree, sync and power requirements.
- RCI-AI-019How can a robot synchronize a USB depth camera and an Ethernet LiDAR?
Tests hardware trigger, PTP, timestamp domains, host latency, calibration and evidence limits.
- RCI-AI-020What evidence is needed to call a robot battery, BMS, charger and connector compatible?
Tests voltage/current limits, protocol, pinout, protection, thermal and certification evidence.
Manufacturers & replacements
- RCI-AI-021Which integrated robot joint vendors publish both continuous and peak torque with usable test conditions?
Tests source-backed vendor discovery without converting incomplete public data into a ranking.
- RCI-AI-022Which compact 360-degree 3D LiDAR sensors weigh less than 300 grams?
Tests cross-vendor filtering with mass, FOV and product-variant evidence.
- RCI-AI-023What are current alternatives to the RealSense D455 for robot depth sensing?
Tests replacement reasoning by range, transport, timing, environment and software—not superficial similarity.
- RCI-AI-024How do NVIDIA Jetson AGX Orin and Qualcomm Robotics RB5 differ for synchronized multi-camera robots?
Tests camera I/O, acceleration architecture, software, power and carrier-board boundaries.
- RCI-AI-025What evidence is required before calling one discontinued robot actuator a drop-in replacement for another?
Tests mechanical, electrical, protocol, control, thermal, lifecycle and validation evidence.
Standards, evidence & change
- RCI-AI-026Which standards and test records matter when selecting safety-related robot components?
Tests use of official standards while avoiding claims that component certification alone certifies a robot.
- RCI-AI-027Does UN 38.3 prove that a robot battery pack is safe for operation?
Tests the distinction between transport testing and application-level electrical, thermal and functional safety.
- RCI-AI-028How should changes between two versions of a robot component datasheet be recorded?
Tests document identity, revision, field-level diff, downstream impact and non-silent correction.
- RCI-AI-029What is the difference between a manufacturer claim and independent verification for robot hardware?
Tests RCI’s core evidence-state distinction.
- RCI-AI-030Which public humanoid robot projects disclose their joint actuator suppliers or a verifiable bill of materials?
Tests whether public BOM evidence is distinguished from teardown inference and repeated media claims.
