Technical articles on 3D multi-line LiDAR navigation chassis, mobile robot selection, and humanoid robot chassis.
Start with four hard metrics: payload, runtime, localization accuracy and avoidance dimension. Full Tbot lineup of 7 structures in one table — N5-3D/OW-3D/X2/S series/X series/ACK15/MW, matched by scenario, plus three common misconceptions.
Read more →Field notes from the hardest commercial cleaning scenario: wheel stops, speed bumps, sunken manholes, hanging ducts, dense pillars. Tbot-Clean-U75 carries a single 3D multi-line LiDAR — point-cloud avoidance, edge cleaning, night operation; 15° slope, 2cm obstacle, 56cm aisle.
Read more →A new option for workshop transport: single top-mounted inverted 3D multi-line LiDAR, point-cloud avoidance for low objects, overhead objects and cliff-drop protection. 500×200mm-800×200mm, 100-300kg, built for cart docking and narrow aisles.

Read more →Industry insight: sensors from stacking to convergence, from showcase to delivery, from bipedal-first to wheeled-first. A single 3D multi-line LiDAR benefits reliability, compute, cost and maintenance — why our full lineup stays single-LiDAR.
Read more →Developer tutorial: power-up and e-stop checks, 3D point-cloud mapping, localization and navigation, region-based avoidance, simulation to real robot. Open ROS interface — reuse your upper logic, change models without changing the framework.
Read more →Expo review: many humanoids but diverging chassis, sensor convergence, scenario delivery as the main theme. The robot is the "face", the chassis is the "substance" — a single 3D multi-line LiDAR is becoming the mainstream for the next generation.
Read more →Company news: partnership with large robot contract manufacturers, standardized lines and strict QC; professional after-sales team with real-time response. Years of Tbot R&D + university research transfer + deep factory cooperation + pro after-sales — a four-segment loop.
Read more →A 350K-view Zhihu debate on "why are we obsessed with humanoid robots": storytelling for funding, engineering reality and emotional value. A wheeled chassis first solves standing stable, running long and affordable repair — one 3D multi-line LiDAR handles spatial perception: low, suspended and drop-off obstacles in one view.
Read more →Zhihu debate on choosing commercial cleaning manufacturers: labor shortage, hygiene standards and scaled deployment are consensus. The real watershed is the navigation architecture — parking stop bars, potholes, suspended pipes, edges and steps: one 3D multi-line LiDAR vs 15+ stacked sensors.
Read more →Three hot Zhihu questions: which SLAM for home vacuums? how do they avoid obstacles precisely? LDS vs ToF navigation? Top consensus — navigation is mature, avoidance is the hard part; area-array ToF multipath is unsolvable, single-line LDS has a height blind zone. Commercial cleaning robots have no dilemma: one 3D multi-line LiDAR, point-wise ranging resists multipath, vertical FOV sees low obstacles — SLAM+avoidance+mapping in one.
Read more →A viral Zhihu article maps cleaning robot navigation into five generations. We agree with the arc but disagree on the endpoint: Gen-4 LiDAR+stereo+ToF+ultrasonic is a patch, not the end state. One 3D multi-line LiDAR already covers all four. VLA is the manipulator layer, not navigation.
Read more →The Zhihu debate "LiDAR vs pure vision" is an outdoor L3 car argument. For indoor mobile robot chassis, the engineering optimum has converged: one 3D multi-line LiDAR does localization, obstacle avoidance, mapping and cliff detection — sensors cut from 4-5 to 1.
Read more →Omni-wheels are not "better wheels" — they are a different motion paradigm. Compared with differential and Mecanum, why is Tbot-OW-3D + a single 3D multi-line LiDAR one of the best indoor precision-mobility choices for humanoids? ±10mm docking, no jockeying in narrow spaces, sensors cut from 4-5 to 1.
Read more →A single multi-line LiDAR achieves spatial 3D obstacle avoidance, eliminating the need for single-line LiDAR, depth cameras, ultrasonic sensors, and anti-cliff sensors. Why are more humanoid robot makers choosing 3D multi-line? How does it compare to traditional single-line solutions?
Read more →Underground parking, supermarkets, campuses, factories—cleaning robots must detect pits, cables, water pipes, parking stops, and edge-following. Why is single-line LiDAR insufficient? Tbot-Clean-H1/U1/X1 navigation kit analysis.
Read more →Full Tbot chassis comparison: N5-3D 6-wheel mid-drive differential, X2 front-drive 4-wheel, S5/S8/S12 rectangular, X4/X100 4WD, ACK15 Ackermann, MW Mecanum, OW omni-wheel—100-500kg payload, choose the right structure for your use case.
