HD2 Treaded Robot
Standard HD2 Treaded Robot Features:
• Wheels supported with inner and outer race sealed ball bearings (the wheels are NOT cantilevered or direct driven from the gear motor shaft).
• Wheels are driven with powerful 52mm diameter gear motors with heavy duty #35 chains.
• The treads and four powerful motors allow this robot to ascend/descend stairs and go over most terrain.
• Robot is enclosed and can be sealed making it water tight.
• Chassis is made from aircraft grade aluminum. The design uses all laser cut parts with mortise and tenon design for precise alignment and
mating of the parts. The frame is ribbed and gusseted making it very rigid. Welded construction using TIG and MIG for a solid chassis.
• The robot is completely symmetric and invertible.
• It is about 38 inches long and 20 inches wide by about 9 1/2" high (tread height). There is a very large center cavity for batteries, electronics,
cameras, computers, etc. Wider chassis are also available (~26” wide).
• Weight is about 60lbs with standard motors and no batteries.
• The bottom cover is flanged and all the holes are laser cut and then hand tapped for a perfect fit and seal.
• Custom Treads with aggressive All Terrain pattern. Positive traction. The composite rubber and UHMW wheels with timed teeth that match
the cutout pattern on the treads.
• NiMH Battery power options from 4-20Ahrs
• Videos are available of the Treaded ATR on our HD2 support page (http://www.superdroidrobots.com/HD2.htm).
HD2 Motor and Gearing Options:
• A large selection of motors with or without
encoders.
• The robot is geared with a 1:3 reduction (gear
motor to drive wheels). The OD of the wheels
with the tread is about 9.4 inches, so with the
recommended Type 02 IG52 290 RPM
motors ground speed is about 4 ft/sec.
• Custom gearing can be requested resulting in
speeds up to 6ft/sec.
• With two 10000mAHr NiMH batteries, the
robot handles additional weight without
issues. See our support page for a video of
the HD2 carrying a 50lb weight around.
• The HD2 can also be set up with four Type
02 IG52 103 RPM motors or Type 04 136
RPM motors and it’s virtually unstoppable.
See our support page for a video of the HD2
pulling an F250 Truck.

1. The current draw is approximate average. Higher inrush spikes, etc will be experienced.
2. The robot weighs about 60lbs with motors. The weight of the batteries, sensors, controllers, aux
equipment, cargo, etc should be added to this to get the gross weight. The robot itself is designed to carry
even more weight, but since its skid steering, turning in deep grass, carpet etc will be difficult with heavier
loads. If using on smooth surfaces, dirt or other low friction surfaces, pivot turning with heavier loads can
be achieved.
