Distributed mobile robotics DMR involves teams of networked robots navigating in a physical space to achieve tasks in a coordinated fashion. A major challenge in DMR is to program the ensemble of robots with formal guarantees and high assurance of correct operation.

This paper makes three central contributions: 1 We present a novel and provably correct decentralized asynchronous motion planner that can perform on-the-fly collision-free planning for dynamically generated tasks. Moreover, the motion planner is the first to take into account the fact that distributed robots may have clocks that are only synchronized up to a tolerance, i.

Using our abstraction-based verification approach we were able to find, within a few minutes, bugs which could not be found by performing random simulation for several hours. Our verified decentralized motion-planner scales efficiently for large number of robots upto robots and workspace sizes upto a x grid.

We present simulation videos for various configurations by varying the number of robots in the system and the grid size.

The orange blocks in the workspace represent static obstacles and green blocks represent potential goal locations for the robot. During simulation tasks represented as taskId, goalLocation are randomly generated and sent to the robot. Each robot on receiving a task request, dynamically computes the path using the multi-robot motion planner implemented in Drona.

The simulator uses ROS and Rviz. In this simulation, there are two robots that are assigned a task to go to a particular green location. The path on the left is shorter than the part on the right for both the robots.

We conduct a series of experiments for different values of delta. You could see that the drones keep sufficient distance among themselves and being conservative with respect to delta. This demo demonstrate that our motion-planner considers time-synchronization error and in the presence of that computes the optimal path. During this mission the drone is executing the generated code from drona framework.

The task planner is continuously sending the next location in the grid to be surveyed and the drone visits that location and waits may be takes an image : When the mission-completed message is sent by the task-planner the drone dynamically computes path to the home location and returns.

The Dorna object has a default configuration. You can initialize the Dorna object with your own custom configuration file:. After initialization step, we need to establish a communication link between the Dorna object and the robot controller box.

First, plug your USB cable into your laptop and the controller box. The first thing to do is to make sure that your firmware is up to date. You should see a successful status code 0and a message: "firmware updated". Now we need to set the absolute machine coordinates to a known position. This is known as the homing process.

Each joint j0, j1, j2, j3 and j4 is either homed 1or not homed 0. Note that the homing status of j3 and j4 are coupled to each other. This means, they are both either homed, or not homed, and homing one of them also home the other one. You can check the coordinates of this position with the.

After a successful connection, the robot is ready to receive and execute commands. Each command is a JSON object with three main keys:.

Each Dorna object has a queue submission queue which is responsible for holding submitted commands. Commands in the submission queue will be sent to the robot one by one. For more detail on commands, visit the wiki. Note that we can group multiple commands together as an JSON array, and feed them all to the submission queue, instead of sending them one by one. This command moves the robot to the given point in space. During a move command, the robot moves from an initial point start pointto the end point.

The end point positions can be given either in the joint coordinate system or the Cartesian coordinate system format. This command stops the program and waits for the inputs to match the input pattern. If the pattern appeared then the program proceeds. Note that this command only takes one input as a parameter. This command is able to set outputs, mode of inputs and outputs, laser and servo. This command suspends execution for the given number of seconds.

The number of seconds is the value assigned to the "prm" key. The Dorna object runs multiple threads in the background.

Return a JSON object with two keys "status" and "message" :. Notice : The connection process can take few seconds.

During the connection process, the connection status of the robot is 1 connecting. If the connection process is successful then the connection status of the robot changes to 2 connected.

Otherwise, if the connection process is not successful for any reason, then the connection status changes to 0 disconnect. Return Return the robot status via. Completely terminate the Dorna object. After a successful connection, the robot is ready to receive and execute commands. Each command is a JSON object with three main keys for more information on the list of available commands, visit the commands page :.

Each Dorna object has a queue submission queue which is responsible for holding submitted commands. Commands in the submission queue will be sent to the robot one by one. After submitting commands, the API assign additional keys to each command, in addition to the initial keys. The keys and the value assigned to them are including the initial keys :.

First, a command is submitted, and it goes into a submission queue and waits there for its turn state 0. The robot takes, processes and executes the command state 1.

Dorna API Quick Start

Finally, when the execution of a command is over then the command process is done state 2. Use this method to submit commands to the submission queue. Notice : We can group multiple commands together as an arrayand feed them all to the submission queue, instead of sending them one by one. The main benefit of sending multiple commands especially for the "move" command at once, is that the robot can plan all the motions ahead of time and execute a better smoother motion.

If the submission is successful then it will return a JSON array with the list of submitted commands via. Otherwise, it will return a JSON object explaining the error. Flush and return every all the commands from the submission queue. Notice that the. Return a JSON array with the list of all commands in the submission queue commands with state 0.

Stop all the motions, and flush every commands from the submission queue and the robot commands with state 0 and 1. A JSON object that contains multiple keys. If a value assigned to a key is nullthen the status of that key is unknown. Return the current position of the robot in a JSON array format. The potion can be returned either in the joint coordinate system or the Cartesian coordinate system xyz coordinate system.

The space variable specifies the coordinate system of the returned position. If the input space is not set then by default space is equal to "joint". The length of the returned array depends on the number of axes in the robot.The blue curved arrows define the positive rotary direction for the associated joint. So, at any moment the position of the robot and its geometry can be uniquely identified by the values of the five joints J0, J1, J2, J3, J4.

We can also define the XYZ Cartesian coordinate system for the robot. After fixing the origin, we set X,Y axis in a manner that they form the bottom plane, while Z axis forms the height. Another important concept in the robot is the position of the tip of the toolhead of the robot head. We use two different coordinate systems to identify this position.

As we mentioned earlier given the values of the five joints as a tuple we can uniquely identify the position of the head of the robot.

In this system, X,Y and Z represent the position of the head of the robot in the Cartesian coordinate system and. You can install and operation Dorna either on the ground or to the ceiling. You can attach different toolheads to the head of Dorna using any combination of the 9 different tapped holes on the head of Dorna.

Screw size of can be used for attaching toolheads to Dorna. We recommend at least using two screws to securely attach the toolhead. Please note that:.

After you have installed the downloaded file, launch the application. You will be redirected to a web browser where Dorna software is launched as a web app. After USB connection is successfully established between the robot and the software, the robot needs to be homed. The term homing in this context means setting the absolute robot coordinates to a known coordinate. The homing of the robot is achieved one axis at a time and during the process the robot searches for the known position of homing sensors.

There are four homing buttons, one for each joint 1, joint 2 and joint 3, and one for joints joint 3 and Joint 4 together. Homing usually takes few seconds, during this period, any interrupts such as jogging or running a script will terminate the homing process. The robot is homed if all the joints are homed. In this case, a green dot appears on the top left side of the homing icon. Then follow the homing steps again. In this case, we need to calibrate the device and assign the true values to each joint.

This is specially important if you plan to work with Dorna in X-Y-Z coordinates as the offset will introduce an error to the X, Y, Z values. From now on, the robot joints will show the true value based on the calibration accuracy. The calibration needs to be done only once.

The result of the calibration is saved in a config file inside the software folder and whenever the robot is homed, the calibration values are applied. In Dorna software you can update the length of the toolhead tool length based on the toolhead that you are using. The correct length of the toolhead is specially important if you work in X-Y-Z coordinate system, and you are interested in X, Y, Z values of the tip of the toolhead.

The tool length is calculated in inch, and it is the length between the center of J3 joint and the end of the toolhead. Jerk is the rate of change in acceleration which is the third derivative of position as a function of time. Dorna uses a constant jerk motion profile. When a joint starts from zero speed, it uses a constant jerk to accelerate up to a max speed.

Then the speed is constant until a deceleration is needed.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
