The lightest Orbbec stereo depth camera in our catalog is the Orbbec Gemini 305 at 68 g — a good fit for a small robot gripper. orbbec.comorbbec.com ↗“Orbbec Gemini 305 | 68 g”
Why it fits a gripper mount:

One caveat: of the 12 Orbbec stereo depth cameras in the catalog, 11 list a weight and 1 does not, so the Gemini 305 is the lightest among those with a stated weight — I couldn't verify the weight of that one unlisted product. Also note the Gemini 335/336 offer 1080p RGB if you need higher color resolution at the gripper, and the 305g/335Lg variants add GMSL2 for longer, more robust cabling if your gripper sits far from the compute unit.
