GPK-32 Inspection Robot

The GPK-32 is our most popular inspection robot. It can be used to inspect any tight space that is safe for a robot to operate in, but is most commonly used by home inspectors for crawlspace inspections. As such, it has been tailored for that environment, but customers have found many other uses for the robot that we never originally imagined. It has been used to look for leaks under vehicles, to inspect train cars, and to run cables under the floors of large buildings. Below you will find an overview of the robot, as well as answers for most questions about using it, and help with troubleshooting issues you might encounter.

Basic Detail

Dimensions (L x W x H)	12.5” x 10” x 7.25”	Small enough to fit in many confined areas.
Camera	RunCam 2 HD 1080P	The camera is fully controllable from the robot’s controller and captures HD photos and video on a Micro SD card making it easy to transfer photos and video to your computer for use in reports.
Control	2.4GHz Wireless RC	The robot and camera are easy to operate with the RC controller. The left joystick tilts the camera up and down, and the right joystick moves the robot.
Video Transmission	5.8GHz Analog Low Latency	A live feed from the robot’s camera will be displayed on the monitor attached to the controller. This is an analog video signal that will have no noticeable delay, and good range, but will not be a crystal-clear HD image.
Range	Up to 500 Feet Line of Sight	The maximum range is line of sight and will drop as obstacles are introduced. It is sufficient for most crawlspaces, but if the signal degrades you can simply move around closer to the robot either from above or outside the structure.
Camera Movement	Tilt ≈ -20° to 75°	The camera tilts to look down right in front of the robot and up to see almost directly above the robot. The camera itself does not pan, but the robot is skid steer so it can turn on a dime in tight spaces to see to the sides.
Lights	≈ 400 Lumens	The lights work well in confined spaces and in a very large dark space it lights up to about 10 feet in front of the robot.

Frequently Asked Questions

Question: Can the robot take photos?

Answer: Yes. The camera is set up to begin recording automatically when the robot turns on, and you can take pictures while the robot is recording without interrupting the video. You can also stop the recording and switch the camera over to photo mode to take higher resolution pictures, all from the remote control.

Question: What is the run time?

Answer: The robot comes with two DeWalt batteries. Each fully charged battery will run the robot for about two hours, and charging each DeWalt battery takes about 30 minutes.

Question: What is the range?

Answer: The maximum line of of sight range is about 500ft. This will obviously go down as obstructions are placed between the controller and the robot. The range is generally sufficient to reach the far side of a crawlspace from the outside, but if you begin to loose the connection you can move closer to the robot either from above by being inside the house, or by moving around the exterior to the other side of the house. Strong WiFi signals, or any other signal in the 5.8GHz range can cause additional inference in the video feed.

Question: Is there a warranty?

Answer: Yes.

• SuperDroid Robots will repair any manufacturing defects for 1 year after shipment.
• Damage from abuse or neglect will not be covered.
• Any shipping costs are the responsibility of the purchaser.
• Unlimited technical support.
• Consumable items will not be covered by the warranty. Consumable items include, but are not limited to treads/tracks, bearings, wheels, and batteries.

Question: How to use the Micro SD card?

Answer:

Micro SD card slot location

The robot comes with a 16GB Micro SD card, and an adapter so that you can plug it into your computer. The small card goes into the camera with the metal contacts facing up. The Micro SD card slot on the camera is small and hard to see when you are not used it. Make sure that the robot is turned off, and tilt the camera all the way down. If you are outside with the robot on the ground, then it helps to lift the back of the robot up off of the ground and rest it against yourself so that the nose of the robot is facing the ground. Unplug the camera to get the wire out of the way, and carefully slide the card into the slot show in the picture. The slot is inside the large opening, just under the top right edge. Once the card is started in the right place, push it in the rest of the way until you hear/feel it click into place. To remove the card you must push it in so that it clicks to unlock and then it will come right out.

Question: What to do if my video monitor needs to be charged before I'm done inspecting

Answer: The video monitor has about a 2 hour runtime, just like the robot. Unlike the robot, it does not have an external battery that can be swapped out when it goes dead. Simply keeping it charged between jobs works well for most people, but another great solution is This product. The provided link is an adapter that will use one of your DeWalt batteries to provide power to the monitor. This allows the monitor to be used more contentiously through mobile charging.

Question: Why does the GPK-32 not use a GoPro camera?

Answer: The GoPro is a very popular, and very good camera, but it does not meet all of our requirements. The very first version of this robot did use the GoPro, but the biggest problem is the connection method. The only way to connect to the GoPro camera to see the video feed from the robot and have control of the camera is by using the WiFi on the camera to connect to a phone or tablet. This does have some benefits, but it has more drawbacks for most users. The range is extremely limited. You must stay very close to the robot in order to maintain the video feed. There is also a delay in the video feed that means when you move the robot, you don't see that movement immediately on screen.

Question: Is an inspection robot the right tool for me?

Answer: The thing to remember is that inspection robots are tools. They can not replace a skilled inspector. Buying an inspection robot does not mean that you will never crawl under a house again. There will be times that you get the robot stuck and must retrieve it, or can not reach an area with the robot. Inspection robots are simply tools to help you do your job. They will not be the right tool in every situation, or for every person, but when used properly they can absolutely help you do your job more safely, easily, and quickly.

Troubleshooting

The controller is beeping, and won't connect to the robot.

Controller switch and joystick positions while turning on and connecting to the robot

Every time you turn on the controller, before it will connect to the robot, the four switches across the top of the controller must be in the up position, and the left joystick must be pulled all the way down towards you. Do not touch the right joystick during this process.

The robot moves on its own right after turning it on

This relates to the issue above. Be sure not to touch the right joystick when turning on the remote control. Each time the controller is turned on it checks the position of the right joystick and uses the position at startup as its zero point. It does this to prevent creep from getting into the stick over time as it wears, which is good, but it means that if you are touching the right joystick when it connects it will take that as the new zero point and when you let go it will register that the stick is being moved which will make the robot move. Basically, if you turn on the robot with the right joystick held all the way down it will stay still as long as you hold the stick there but as soon as you let go the stick will return to center and the robot will start driving forward by itself.

The video feed isn't clear

The video being transmitted from the robot to the monitor is analog so it will always have bits of interference, but the range is greatly increased from that provided by a WiFi connection. It is also very low latency so that you are seeing the robot move in real time, rather than with the delay you get from a WiFi connection. The most important thing is to be sure the antennas on the monitor are pointing straight up so that they match the orientation of the antenna on the robot. Once you find the most comfortable position to hold the controller, adjust the antennas on the monitor to be pointed straight up. If you are experiencing excessive interference while not very far from the robot, it is likely that something in the area is either blocking the signal or another signal is interfering with it. There isn't a whole lot you can do about a competing signal in the area, but if it is a block then moving to a different location to get a different angle to the robot can help. Sometimes the video feed will begin to go out, but come back once you are past whatever is interfering with the signal.

The video feed is snowy with no picture

If we are sure that the robot and camera have turned on properly but the feed is still all snow, even right next to the robot, then it is most likely that either the band or channel on the monitor have been changed. We want the monitor to be set to "Band:R CH:8". Follow the steps below to get the monitor set back to the right place.

Step 1: Turn on the robot and the monitor.

Step 2: Tap the ">/CH" button once. This will cause band and channel to turn red in the upper left corner of the monitor.

Step 3: Quickly tap the "</BAND" button while the text is still red until the upper left reads "BAND:R" (if the text turns white before this step, tap the ">/CH" button once again to turn the text red once more).

Step 4: Tap the ">/CH" button until the upper left reads "CH:8"

The monitor screen is turned on, but is just black with no image or snow

The most likely cause of this is the monitor having accidentally been put in the wrong mode. The button just to the left of the power button (with a sideways U-turn arrow under it) is the Mode/Return button. Tapping it will cycle between "Video" and "RF". We want the monitor to be on "RF". Tap the button until you see a box in the upper left corner that says "RF".

The robot is getting stuck, or rolling over

The GPK-32 is not indestructible or unstoppable. You can absolutely get it stuck. The biggest thing to keep in mind for not getting stuck is route selection. You should pay attention to what you are driving on, and driving over. The easiest way to get stuck is to high center the robot. This happens when you drive onto something that lifts the body of the robot slightly so that the tracks are no longer making good contact with the ground. A good example is a small pipe running on the ground. If you drive over that pipe at 90 degrees there will be no problem, but if you drive onto that pipe and then turn to drive down the length of the pipe, the robot will be balanced on the pipe with the tracks no longer having good traction. Once you end up in that position with no traction, there is very little change of getting unstuck because there is no way to impart enough force to the robot. Some customer have tied a paracord line to the handle of the robot so that they can impart force to the robot to get unstuck, but this solution means you have to be aware of a line that is dragging behind you and take care not to tangle yourself. The best solution is to pay attention to the terrain and avoid situations where you are likely to get stuck.
