Here are the schedule of our ROS workshop series during the first three months of 2017!
Venue: Hongo, Tokyo
In the previous post we introduced one of the many new features that were added to MoveIt! with its first update in 2017. Next feature we want to mention is the “stop motion”, which we’ve received many questions from our NEXTAGE users about.
Other than situations where you need to stop robots to move for the safety reasons, there can be many cases you want to stop/cancel/halt your robot for your application. The standard way to achieve this in MoveIt! had been lacking, which is finally organized this time (lead by a student at GSoC project by the way).
It works well with Pepper robot on simulation. You see the arm stops as soon as the “stop” button on RViz was clicked.
This nice feature, however, does not YET work with the NEXTAGE Open. Don’t worry much, there’s a work going on already and we confirmed a patch submitted from a community member solves the issue on simulation! We just need to test the patch on the real NEXTAGE Open robot, and this is where we need a help from the robot owners. If you think you can help us testing with your own robot, please contact TORK at info[a_t]opensource-robotics.tokyo.jp or joint the discussion at the ticket for this issue on Github so that we’ll communicate with you. Thank you for your understanding toward opensource!
New version of MoveIt! binary 0.7.6 is just released for ROS Indigo, first time in 2017 (for sure!) and first release since June 2016. This version comes with some long-wanted features (along with bug fixes of course) that we’re trying out using NEXTAGE simulator.
1. Changing trajectory velocity and acceleration during runtime
Changing the speed of the trajectory during runtime has been one of FAQs from NEXTAGE users who use MoveIt!, let alone many MoveIt! users on the globe. Now through MoveIt! RViz plugin you can conveniently configure that on the fly on the spinboxes added.
To configure that programmatically, see this tutorial that explains chainging MotionPlanRequest topic would do the work.
TORK is very actively contributing the development and maintenance of MoveIt!.
ROS device driver for force-torque sensor Dynpick, one that TORK joins its maintenance, has been known to work for a discontinued product only so far. Now someone in the opensource community just confirmed that the package works with a product that’s still available!
And as always, may the power of opensource be with you. Happy holidays!
