Hi Hernán, not for now, since my main goal is to make possible to program behaviors for the drone using the language LRP (Live Robot Programming). However, since I am using a spiral development method, I may consider it in a further stage. Thanks for the suggestion! Caro About LRP: http://pleiad.

Re: [Pharo-users] New project: AR.Drone communication API in Pharo

Hi Krish Thanks for all your comments. About the #initialize method, I think you are right, and some code refactoring would solve it. Also, about the #takeOff method, maybe the comments are not so explicative, but it just sends the take off command until the drone is actually flying. In practice,

Hi Alex, I read your comment after I posted a response. I don't have so much experience to ROS, and none to PhaROS. But, are you saying that using Gazebo with the API would be somehow straight forward? 2016-04-10 12:15 GMT-03:00 Alexandre Bergel : > Hi Hernan, > > Gazebo uses ROS somehow, so yes.

Re: [Pharo-users] New project: AR.Drone communication API in Pharo

Hi Stef, All communications with the AR.Drone are done via exchage of UDP and TCP packages between the drone's firmware and the client. Packages are sent by a Wifi network, which is managed by the drone's firmware. In addition to this, the firmware automates the flight manouvers (take off, roll, pi

Gazebo/PlayerStage define a common API to control robots. This API is also implement in the Gazebo simulation engine. Please have a look to my PlayerST code. Sent from my iPhone > On 12 avr. 2016, at 06:04, Carolina Hernández wrote: > > Hi Alex, > I read your comment after I posted a response
