These tiny gearmotors are available in a range of gear ratios. All of the micro metal gearmotors have the same physical dimensions, so one version can be easily swapped for another if your design requirements change.
This gearmotor is a miniature (0.94" x 0.39" x 0.47"), high-power brushed DC motor with 100:1 metal gearbox, similar to Sanyo’s popular 12 mm gearmotors. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft.
This complete inspection robot package includes Dewalt Battery Mount, 2 Dewalt Batteries and a charger, RunCam2 camera and high power LED lights. It records in HD 1080p. Designed for inspecting hard to reach areas such as crawlspaces and attics.
