SLAMTEC RPLIDAR A1M8 360° laser scanner: base outline, 4 mounting holes, scanning head and motor

What are the SLAMTEC RPLIDAR A1M8 dimensions and mounting-hole positions? · Modern device · basis: SLAMTEC's official RPLIDAR A1M8 2D drawing, with the base outline, hole depths and under-plate parts taken from SLAMTEC's official 3D model.

Also called: RPLIDAR A1M8, SLAMTEC RPLIDAR A1, rplidar a1, slamtec rplidar a1m8 a1 series 360-degree scanning lidar, RPLIDAR A1 mounting hole pattern, RPLIDAR A1 dimensions, SLAMTEC A1 2D lidar

Exact dimensions. Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. Mating features

Notes

  • Upright, lowest point (motor connector) at 0, top of the scanning head at 51.0. Base plate from 21.0 to 26.5 (5.5 thick); the rotating disc is Ø70.28 and the head Ø70.0.
  • The head axis sits 35.14 from the head end of the 96.74 base; the Ø32 drive motor hangs below the plate, flush with the opposite end.
  • Four Ø3.0 mounting holes through the base plate, each with a Ø5.0 × 2.0 counterbore at the plate top: 70.0 apart along the length, 56.0 apart across at the head end and 40.0 apart across at the motor end.
  • Measured from the head axis, the head-end holes sit 28.0 toward the head end and the motor-end holes 42.0 toward the motor end.
  • Modelled: base plate outline, holes, skirt and PCB under the plate (down to 15.0), motor and its connector, pulley, rotating disc and head. Not modelled: drive belt, plate ribs, head window and the loose cable.
  • All dimensions are exact nominal millimetres, true size, with no tolerance added.
