Follow me robot using bluetooth-based position estimation Abstract: Human-Following robots are being actively researched for their immense potential to carry out mundane tasks like load carrying and monitoring of target individual through interaction and collaboration.

The recent advancements in vision and sensor technologies have helped in creating more user-friendly robots that are able to coexist with humans by leveraging the sensors for human detection, human movement estimation, collision avoidance, and obstacle avoidance. But most of these sensors are suitable only for Line of Sight following of human. In the case of loss of sight of the target, most of them fail to re-acquire their target. In this paper, we are proposing a novel method to develop a human following robot using Bluetooth and Inertial Measurement Unit IMU on Smartphones which can work under high interference environment and can reacquire the target when lost.

The proposed method leverages IMU sensors on the smartphone to estimate the direction of human movement while estimating the distance traveled from the RSSI of the Bluetooth. Thus, the Follow Me robot which estimates the position of target human and direction of heading and effectively track the person was implemented using Smartphone on a differential drive robot. Article :. DOI: Need Help?Pages: [1]. I'm planning on building a robot that is controlled via Bluetooth, but also is able to follow the user without as much disturbance.

However, GPS lacks its ability of tracking indoors and IR Beacons have to be in a direct line-of-sight between the robot and user. In some posts that I have found, people made their own ultrasonic beacons where the user carries the beacon and the robot detects the origin of the beacon signal and follows it. And is there an easier alternative to building a robot that follows the user indoors and can be in a small crowd of people? I have the obstacle avoidance figured out, but I need help with the following Thanks!

Let me know any suggestions or answers to my questions. Any help that can be provided will be awesome! If any further clarification is needed let me know. SMM2 Jr. It's built on failure. It's built on frustration. Sometimes its built on catastrophe. I want to build a similar robot that works indoors but mustn't have a line-of-sight with the person at all times. Well, to do something like that the robot must have at least 2 methods of locating you.

So, if the robot cannot follow you using beacons, then it must have another way to find you. This may require the robot to have even more knowledge if you want it to follow you when line of sight isn't possible and not using GPS if you want it to work indoors. Now, we have to figure out that second way Quote from: SMM2 on Jul 13,pm.

This guy built almost exactly what I want to build, however he doesn't explain how he modified the ultrasonic sensor. I'm trying to build this robot on a budget, so I'm thinking of using HC-SR04 ultrasonic modules and possibly a nrf24l01 module for the wireless communication. Will I need an arduino board for the beacon? The guy in the video didn't seem to have one. I feel like I sort of understand this, but the coding and modification of the sensors seems a bit foreign to me.

Thanks for any of your help!!! Does anyone have any idea on how I would build this with a cheaper setup? In the video, the robot sends a wireless message to the ultrasonic transmitter module on the wearertelling it to emit a ping.Add the following snippet to your HTML:.

We use an Arduino to build an autonomous "follow me" cooler that connects to a smartphone via Bluetooth and uses GPS to navigate. Project tutorial by Hacker Shack. In this project, we use an Arduino Uno to build an autonomous "follow me" cooler. The robot cooler connects to a smartphone via Bluetooth and uses GPS to navigate. All the electronics will be contained in the base so that other objects can be carried as well.

We created two videos about the build process for this project. In this first video, Davis explains how to build the base. Standing the boards up on end to create a box helped keep the cooler in place while the base was moving.

We measured the MDF to be about 1 inch larger on each side than the dimensions of the bottom of the cooler. In this case, the cooler was The extra space allowed the 1x3" boards to be nailed on top of the MDF. Our jigsaw worked well to cut this piece. The 1x3" planks were cut to the same length as the depth of the base, but we made them about 2 inches shorter on the width so that they could align with the edges of the MDF.

The planks were attached to the MDF with a few small nails. In order to house the electronics, we made a small box using the same process as the base platform albeit using some 1x2" planks instead of 1x3". We eyeballed the dimensions here, but it turned out to be about 11x9". The electronics box was nailed to the bottom of our platform after we cut a hole in the MDF with our jigsaw. Finally, we added the components for the drive system. The wheels used a couple 3D printed brackets 3D parts provided below to mount our high torque 12v motors.

A 3D printed connector was attached to a metal hub to mount the wheel on the motor shafts. A simple swivel wheel was used on the back of the platform. It was attached with another 3D printed bracket.

The electronics were installed in the box cutout under the platform. We used an Arduino Uno and a 5v battery to power the sensors, Bluetooth, and control logic. A 3s LiPo battery was used to power the motors. A HC Bluetooth module was mounted at the front of the platform for better range. For more information on how we connected the wires, see the diagrams provided in the schematics section below. The motors were powered by drilling holes through the platform and attaching them the LN motor driver board.

The 3s LiPo was connected as the main power source and we tied the ground together with the Arduino power source for control logic. The following image shows what everything looked like once it was connected in the electronics box.

The motorized lid wasn't included in either of our build videos, so we posted some supplemental instructions on how to add it. Our cooler lid had a couple notches that kept the lid snapped shut when it closed. Our servo wasn't strong enough to lift the lid when it was snapped shut, so we used a small Dremel tool to sand down the notches. We used a MGR high torque servo power the lid. We 3d printed a hinged arm to connect the servo horn to the top of the cooler.

In order to keep it in place, we used some gorilla glue. The servo was mounted on the side of the cooler with a piece of 3M double sided outdoor mounting tape. A hole was drilled on the back of the cooler to feed the servo wires through.Don't ad-block us - support your favorite websites.

I've searched out the forums and have found people wanting to do similar things, but the only information was based around IR or cameras.

I'll detail what i want to do for you all: in my pocket i have something putting out a signal on the ground somewhere else, there is a robot doing its usual obstacle avoidance, honing in on the signal. Doesn't SEEM that complex.

Commanderbob Robot Overlord Posts: Helpful? I don't know if you can tell which way the signal is coming from. You would probably need three receivers to compare the different signal strengths and then calculate the direction.

There may be a much easier way to do this, I don't know, just throwing this idea out. Embedded Micro. I'd be interested in hooking up a webcam and using roborealm. Do you have any tutorials about that on the site here? These directly hook up to a microcontroller and do onboard processing for you. If it were an analog camera one could do it using the figure shown on the rollette.

Looks like the analog camera is simply being sent to the computer. No processing. The schematics are a bit grainy, so I might have missed something.

I had the additional interest of getting the webcam data through the serial connection as well to save me a comm. Oscillation Jr.

Member Posts: 8 Helpful? On other websites and robot kits ive seen people use different sensors that you angle towards the front and it follows a moving object, then if it gets to close it drives backwards. However i've only seen this and read about it so i don't know how you'd go about it.

It just means you wouldnt need to have some sort of signal in your pocket all the time. Quote from: Oscillation on June 25,AM. The magazine Robot also had a previous article on a robot called Follow-me. Quote from: ceruleanplains on June 25,AM. Following robot, I did a similar project back in year it was called Follow-Me Robot by using IR beacon transmitter held by user and 2 receiver on the robot platform, it worked quite well, but not good enought compare to Shadow Caddy.

I have four drones quadcopters and hexcoptersbecause I love everything that flies, but the th flight isn't so interesting and starts to be boring, so I decided that I will build my own drone with some extra feutures. I like to program Arduino and design circuits and gadgets so I started to build it. This drone can be connected to an Android smartphone that sends its GPS data to the drone, that compares to its own GPS signal, then starts to follow phone, so if I move on the street the drone follows me.

Of course has many failings yet, because I wasn't able to make a proffesional filming drone, but follows the phone, makes a video and also has a ultrasonic distance sensor to avoid the obstacles in the air. I think this is pretty much features from a homemade drone.

As soon as possible I will load up a video about a flight, but it is hard to make good quality records with an always moving drone. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. The drone is almost fully automatically, you don't have to control it, because follows your phone that is usually in your bike, The ultrasonic sensor helps to bypass trees, buildings and other obstacles and the GPS gives a very accurate position data, but let's see what do we have in total:.

So that is all that the first version can do, of course I want to develop it. During the summer I want to hack my bigger drone with this software. I asked two good friends of me to walk in the front of the drone, while I was under the drone, to save it if falls down.

But the test succeeded, and as you can see the drone still is not very stable, but worked. The left guy in a yellow T-shirt held the phone, that transmitted the GPS data. The video quality with this camera is not the best, but I didn't find low weight p cameras. For this project you need some new and unusual parts. I designed from low wieght and recycled parts to reduce the cost, and succeded I got very good materials for the frame.

But let's see what we need! I bought the Crius brand of the flight controller from Amazon. I bought these proppellers with motors from the Amazon. You just have to put the motor in its hole, and attach the props to the gearing. Now you have to solder all cables from the motors to the LD motor driver IC. Look at the pictures, they say much more, you have to connect black and blue wires to the GND and positive wires to the Outputsjust like me.

The LD can drive these motors, but I recommend to use some power transistors because this chip cannot handle all the four motors at high power more than 2 Ampers.

After this cut 15 cm straws these will hold the motors in place. I used extra strong straws that I got from a local bakery and cafe. Put these straws gently on the motors's gearings. Please pain attention on the second picture, that shows how equip the proppelers. Use some hot glue and super glue to suit all four propellers then check the connections. It is very important that the proppelers have to be by the same distance from each other.

Take four female-female jumper wires and cut the in half. Then solder them to remaining pins of the IC.Thank you so much community you have been always helpful! Best Answer 5 years ago. Tough question.

There are multiple ways of approach. I used this kind of tracking to make a robot play football once. The transmitter sends out a click and the sensors will carefully listen to this click. By determining which one would hear the click first the robot can figure out which is is closer. The user would carry a radio transmitter. The robot would have a Directional Receiver or 2 listening for the broadcast.

Ive seen a project where someone created a Directional Wi-Fi tracker by placing a WiFi module in a servo-rotated metal tube created out of tin-cans! The big problem is that you would need to figure out a way to measure the signal strength It is tricky, but it would make a epic Instructable if somebody does this.

Have been working on same problem until I found this an hour. I had a friend ask a similar question of me the other day. I'm sure you could do something with GPS modules as they can have a pretty decent location resolution. You and your bot would each have one and be connected through a pair of bluetooth modules as well, and then the bot would calculate speed, direction and distance to catch up.

If nothing happens, download the GitHub extension for Visual Studio and try again. While in GPS Streaming mode, the cooler will follow you by streaming coordinates from your phone. In GPS Waypoint mode, you can send a predetermined set of coordinates that the cooler will travel to. Disclaimer: When testing the cooler, we noticed that the GPS coordinates streamed from Blynk were often inaccurate. While it works for some locations, it doesn't for others.

If you want high precision, we highly suggest creating your own Android app to stream GPS coordinates. Open the directory and click the cooler. The Arduino IDE should open with all of the files in that directory. You'll need to configure a few variable definitions for the code to work with your configuration. The most notable is the char auth[] variable. Replace the auth string inside the quotes with the auth token generated by your Blynk app. These pins can be changed by adjusting the following variables in CoolerDefinitions.

Make sure that the following pins are connected to PWM ports we had no available PWM ports left when everything was attached :. In order for our servo-driven lid to work, we had to fine tune the start and stop angle so that we could get the right leverage on the lid. They can be given a value between 0 and Once you have everything configured property, verify and upload the code to your Arduino.

If you are outside, it will take a few seconds for the GPS to acquire a satellite lock. Once it does, it will begin flashing.
