Match devices P ground-penetrating radar, Q tactile sensor, R global navigation satellite system and S digital inclinometer with applications 1 spatial positioning, 2 borehole-deviation measurement, 3 robotic arm and 4 locating subsurface features.
Radar reflections locate subsurface interfaces (P–4). A tactile sensor gives contact feedback to a robotic arm (Q–3). Satellite navigation provides position (R–1). A digital inclinometer measures inclination and thus borehole deviation (S–2). These four matches give B.
