Modified stair climbing rover to carry a robotic arm. Mounting is in the lower frame, servos are rotated 90°, covers and frame have cutouts for the robotic arm. The ESP32 CAM with external antenna is mounted in the top cover, through which everything is controlled and the camera FPV. Arms are modified for versions without servos. The wheels are so fixed and turning is by skid. The discs are modified to avoid the need for motor mounts. Custom printed TPE tires for maximum grip, low material consumption and no supports.
All missing stl files are unchanged in the original models.
