Sensor Selection Calculator

Describe the robot and its environment; get candidate sensor types and combinations with the reasoning, the trade-offs, the integration problems and the datasheet items to check.

Preliminary engineering guidance. The tool ranks sensor types using class-level tendencies (what a LiDAR, a stereo camera or a GNSS receiver typically does). It does not rank products and contains no product specifications. Verify every candidate against its datasheet and test it in your own environment.

Assumptions and limitations

  • Every rating is a class-level tendency written from general engineering knowledge, for example “active-infrared depth cameras are degraded by direct sunlight” or “radar keeps working in fog and rain”. Individual products differ widely and some contradict the tendency.
  • Range limits are order-of-magnitude classes (metres, tens of metres, hundreds of metres), accuracy and rate are coarse classes. They exist to flag obvious mismatches, not to certify a sensor.
  • The role of each sensor in each application (core, common, niche, not typical) is engineering judgement about common practice, not a survey of products or papers.
  • Scoring: role weight, plus adjustments for the conditions you tick, range, accuracy, rate, budget, compute and power. The score orders options inside a function group. Differences of a few points are not meaningful.
  • The tool does not know your mechanical constraints, regulations, safety requirements or supply situation. Redundancy and functional-safety needs are out of scope; see Module 18.
  • Combinations are common starting points. They still need synchronisation and calibrated extrinsics; see Modules 6 and 7.
