What sensors are actually equipped before a robot gets called 'autonomous'

"Autonomous" on a spec sheet is a claim about software sitting on top of a specific, checkable parts list, and the list is shorter than the word implies on more than one AGIBOT platform.

LiDAR and RGB-D are the Ultra-tier option on two AGIBOT lines, not the standard one.

The X2 Basic ships with neither, by AGIBOT's own listing; the X2 Ultra adds 3D LiDAR, an RGB-D camera, front and rear cameras and touch sensors to the same body. The base A3 ships with two RGB cameras, GPS and UWB positioning and no LiDAR or RGB-D at all; the A3 Ultra adds LiDAR, RGB-D and GPS-RTK to that same camera pair. Buying "the A3" or "the X2" without checking which trim is on the order is the most common way a spec sheet's autonomy claim and the crate that actually arrives disagree.

The two platforms with no stripped-down variant carry the fullest suites as standard.

The A2 Ultra is sold in one configuration, and it is the richest sensor line AGIBOT publishes: LiDAR, RGB-D, a fisheye camera, stereo cameras, a microphone array, force and torque sensing and an IMU. The G2 is the other single-configuration platform, and its own listing is dual LiDAR, RGB-D, RGB cameras, an 8-channel microphone array, ultrasonic sensing and fingertip visuo-tactile sensing. Neither is sold as a bare version, so the sensor question for these two is answered before the order is placed rather than at the trim level.

The quadrupeds' camera and LiDAR specs trade off against each other, and the two D1 models make different trades.

The D1 Max carries twin 192-line LiDAR reaching 120 m across a 360-by-90-degree field, alongside GNSS-RTK, ultrasonic sensing to 5 m and four auxiliary lights, plus two FPV cameras at 8 megapixels with a comparatively narrow field of view. The D1 MaxPro halves the LiDAR line count to a single 96-line unit but states an accuracy figure the D1 Max's own listing does not, 1.5 cm, and swaps the D1 Max's narrower cameras for two wide-angle 2-megapixel units instead. Neither spec sheet is simply better than the other: one buys resolution and range certainty, the other buys a wider field of view and a stated accuracy number, and which trade matters depends on whether the job is spotting a small defect or covering a wide approach.

LiDAR and depth sensing are what let a platform find something nobody showed it, not what let it move.

A platform with neither, like the X2 Basic, still executes a taught sequence precisely and repeatably at a fixed position; what it does not do is locate a part whose position varies or a route nobody mapped by hand. That is the actual line the sensor list draws, and it is a cheaper question to ask before an order than after a robot arrives unable to do the one thing a proposal assumed it could.

Ask for the sensor line item by item, by platform and by trim, before "autonomous" or "AI-powered" gets treated as a specification on its own. On this range it names a parts list, and the list is not the same on every SKU that shares a platform's name.
