Robot cannot move along a planning path with IK

Hello, Recently, I am learning Inverse kinematics with Vrep. I try to learning it by imitating motionPlanningAndGraspingDemo.ttt & motionPlanningServerDemo.ttt . But my robot can not move all the time. I carefully check those differences between my project and the former Demo. I have spend several d...

restart the simulation when collision happens

Hello, what I want to do is when collision happens, restart the simulation, so I judge if there is collision I first stop the simulation and then start the simulation, the relative code is: res1, _ = simReadCollision(collisionHandle) if (res1 == 1) then res1 = 0 print("Collision!") simStopSimulation...

Re: the body and wheels of model are separated after collision

Thank you, the demo works successfully now. Actually what I ultimately want to do is to reset the position of the robot through remote API. But simGetObjectsInTree, simResetDynamicObject and other relative functions seem not to have remote API form. Do you have more suggestion? Thanks.

the body and wheels of model are separated after collision

I build a robot model based on pioneer p3dx.ttm, then I program to judge if there is collision between the robot and obstacles(left_wall, right_wall) in the scene and if there is then the robot will be set to the original position. But when I run the simulation, the wheels of the robot model don't r...

How to calculate the coordinate by depth, resolution and perspective angle

Hi, coppelia Recently, I try to use depth sensor to calculate a world position of a pixel. I see the sensor is different from real camera. I am not sure if the method that is used to calculate a position by perspective angel and depth is right. camXHalfAngle = camXAngleInDegrees * 0.5 * math.pi/180 ...

Re: how to connect between Vrep3.4 and ROs(kinetic)

Sorry, the instructions shipped with V-REP 3.4.0 are now outdated. Saxon is not used anymore now, and xsltproc is used instead, so you will need to sudo apt-get install xsltproc . Also you don't need to install v_repStubsGen somewhere in the $PYTHONPATH anymore, as now it is included in the plugin'...

how to connect between Vrep3.4 and ROs(kinetic)

I found some information about the problem, like "http://analuciacruz.me/articles/RosInterface_kinetic/" , "https://github.com/lagadic/vrep_ros_bridge.git". (1) For vrep_ros_bridge, can it still be installed on ubuntu16.04 with Vrep3.4 and ROs(kinetic) ? (2) For RosInterface , I always meet mistakes...
