The Bulldog is a tracked tactical support robot built for the jobs where distance matters. It gives teams a way to look, listen, move objects, open doors, and check hazardous areas without sending a person in first.
It keeps the balance that made the Bulldog one of our best-known tactical robots: enough size and weight to do useful work, enough traction to handle stairs and mixed surfaces, and a removable arm that can be installed or taken off as the mission calls for it.
Robot
| Length | 28 inches |
| Width | 18.5 inches |
| Ground Clearance | 2.75 inches |
| Weight | ~60 pounds |
| Speed | 3+ MPH |
| Runtime | Up to 8 hours depending on package |
| Chassis | Weather-resistant tracked chassis with aluminum construction |
| Origin | Made in the U.S. |
The removable 6-axis arm is what turns the Bulldog from a mobile camera into a useful tool. It can reach, inspect, push, pull, grab, carry, and help open doors while the operator stays behind cover or outside the hazard area.
When low clearance matters, the arm can be removed. With the arm installed, the Bulldog can work handles and knobs, look over furniture, move suspicious items, and get a camera or gripper into places a fixed camera cannot reach.
6-Axis Arm and Gator Grip
| Vertical Reach | 60 inches from the ground |
| Horizontal Reach | 49 inches from the base of the arm |
| Door Work | Opens flat, round, and bar-style door handles and knobs |
| Payload | Lift and carry up to 10 pounds with the arm extended |
| Grip Force | Up to 10 pounds of force between the jaws |
| Gripper | Gator Grip with easy-replace grip inserts |
| Controls | Streamlined arm controls with preset stow position |
The Bulldog arm can be controlled in three ways. Different jobs call for different precision: command the gripper, hold it while driving, or move each joint directly.
Bulldog Lite includes Joint mode only. Standard Bulldog and Bulldog Pro add Gripper control and Hold, plus primary clash avoidance to help avoid obvious arm, gripper, and body conflicts.
Control Modes
| Gripper control | Move the gripper where you need it while the arm joints follow (Bulldog and Pro) |
| Hold | Keep the gripper fixed while driving the chassis (Bulldog and Pro) |
| Joint | Direct control of each arm axis (all packages) |
| Clash avoidance | Helps avoid obvious arm, gripper, and body conflicts (Bulldog and Pro) |
Good camera coverage changes how a robot is used. The Bulldog can be configured with drive cameras, arm cameras, gripper views, and a rotating pan-tilt-zoom camera so the operator is not guessing what the robot is about to hit, grab, or drive over.
Cameras and Recording
| Drive Cameras | Front, rear, and downward views |
| Arm Cameras | 360° view of the arm and gripper area |
| Gripper View | Close view inside the gripper that rotates with the gripper |
| PTZ View | 10x+ zoom with 360° rotate, pan, and tilt capability |
| Night Work | IR lighting for day and night vision on front and rear views |
The Bulldog is designed to move through practical indoor and outdoor environments: typical residential and commercial flooring, fabric, stairs, thresholds, mixed surfaces, and other places where wheels are a poor fit.
The tracked chassis can ascend and descend stairs without flipper arms or a special stair mode. It also keeps a tight turning radius, which matters when the robot is inside a hallway, room, or confined approach path.
Drive and Power
| Tracks | Goat Traction tracks with easy-replace design |
| Stairs | Ascends and descends stairs without flipper arms or stair mode |
| Turning | Tight turning radius for indoor maneuvering |
| Robot Batteries | High-power Lithium-Ion batteries |
| Charging | Easy charge from a standard 120V outlet |
The OCU is built for real control, not just a touch screen. It gives the operator physical thumb sticks, push buttons, indicator lights, a mic, speaker, power switch, antennas, and a 10-inch display for camera feeds.
Operators can view one, or all 4 feeds on the controller, talk and listen from a distance, record video, take snapshots, and connect external devices using USB, audio, HDMI, or Ethernet.
OCU and Range
| Screen | 10-inch display |
| OCU Runtime | ~8 hours |
| OCU Size | 13.25 inches long, 6.25 inches tall, 2.25 inches deep |
| OCU Weight | About 3.5 pounds |
| Wireless Range | Up to 1,100 feet line of sight |
| Through Walls | Up to about 385 feet through two brick walls |
| Tether | 328-foot suggested maximum when using a wired tether, cable not included |
These robots are built to order. Current lead time is shown on quote, and expedited delivery may be available depending on the build queue and configuration.
If you are still working through the package options, we can ship a Bulldog to your facility for a self-guided demo. You get the robot, the OCU, and the camera setup you would expect on a standard evaluation unit.
The demo runs for two days on your site. Your team drives it through your doorways, stairs, and hallways while we stay off-site. Setup notes are included, and we are available by phone if something does not look right when the robot arrives.
A tactical robot has to do more than drive a camera into a room. The Bulldog gives operators a way to see, communicate, manipulate objects, and make contact with the environment before people move closer.
It is large enough to climb stairs, work doors, and carry useful tools, while still being manageable for teams that need a transportable robot for patrol, response, training, and standby work.
We have shipped Bulldog-family robots for more than fifteen years, and units from the early builds are still running well. That history drove how we designed this generation. We looked at what failed in the field, what tied teams to factory service, and what made parts hard to find five or ten years down the road.
The current Bulldog is modular. Most repairs can happen on site, in your shop or bay, without sending the robot back for factory work. Routine assembly and disassembly are meant for someone with basic mechanical skills, not a specialist electrical or mechanical technician. Wiring is plug-and-play. There is no soldering in the service process.
