Setting up Dorna
Does Dorna require a specific AC voltage to work?
Dorna can work with 110V to 230V AC power outlets. You do not need to adjustment for it to work.
How can I install Dorna on a surface?
Make sure you choose a flat and firm surface for safe and vibration free operation of Dorna. There are four 1/4″ (6.35mm) installation holes on the bottom of Dorna which are 2.5″ (63.5mm) apart. Use four 1/4-20 or similar metric sized screws and nuts to secure the arm to the surface.
Can I operate Dorna upside down?
Yes. You can operate Dorna in an upside down position. Make sure the installation is secure. Before powering the robot off, make the clearance needed for the arm as the motors do not hold their position when power is off.
Do I need to place the arm in a specific position before turning it on?
You need to place the arm in a resting position. Please see the help page for more details.
Is a computer needed for operating Dorna?
Yes. Dorna needs a computer connection for proper functioning. The connection is through USB cable. You can operate Dorna using Mac OS, Windows, or Linux using either Dorna software or Dorna API.
Can Dorna be operated wirelessly?
Yes. Using a low cost Raspberry Pi computer, you can remotely control Dorna over a wifi network. For details of implementation you can refer to the tutorials section.
Software and API
Do I need to know any programming language to work with Dorna?
No knowledge of programming of any specific language is needed to work with Dorna. To make a program using Dorna software, you can add commands one by one using the interactive command interface, by filling in your desired parameters. You can also test
What is the difference between Dorna software and Dorna API? Which one should I use?
Dorna Python API is the underlying software that talks to Dorna microcontroller and send commands and receive responses from it. We have made Dorna API completely open source and available for public usage. If you know Python language you can easily download the API and start programming Dorna by just relying on the API. With the API you have access to all the resources available to a Python user including loops, if-else conditions, data structure, and a wire range of other libraries for different applications. Dorna software, is a user web interface built on top of the Python API which makes the interaction and programming of Dorna much simpler. You do not need to know any programming language to work with the software. The software provide a jogging interface which lets the user move the robot to desired locations and save them as part of a program. Most configuration values of the robot are also available in GUI platform for user to adjust. Furthermore, the software, provides a graphical representation of the robot which can be used as a simulator or as a visual guide for programming the arm. As a summary, both Python API and Dorna software are great ways to interact and program the robot. Depending on the application and your level of familiarity with Python you can choose to work with the API or the software.
