an environment that only has end-effector

Hello,

I want to know how to build an environment that only has end-effector and target object and no manipulator body.

The way I can think of it is to make the arm invisible, but I want to directly control the 6 degrees of freedom of the end-effector, not the joints of the arm.


Thanks

Does anybody know where to get a Jaco2 7DOF robot

Does anybody know where to get a Jaco2 7DOF robot model in V-rep?
I tried to get it from kinova-ros package in urdf, but I failed.

How to set object velocity based on current position

Hello, I want my manipulator to work in task space with velocity xd = f(x), that means the velocity is based on the end effector's current position which is known as SEDS, a dynamic system based method. Method 1: if I use IK based method, then I need to set ikTarget velocity xd = f(x), I find sim.rm...

A two-wheeled robot cannot run in a straight line

Dear forum: I am controlling my two-wheeled robot to self-balance and run in a straight line. But, though the same torque is applied to two joints, they gain different speeds and cannot run in a straight line. what should I do to make it work? Thanks

Dear forum : I have a question. My robot works in Newton simulation environment and has a large mass body(70kg), two active wheels, and two passive wheels. The passive wheels are very small and light(0.1kg). I found that when I use light wheels, the wheels will sink below the ground. however, when I...

Different time step have different result

Hi ,I am working on a task about two-wheeled robot platform balance problem and I have two problems. First, I want the robot fall down without any control,just start the simulation when I use step time dt=0.5,need 4 seconds real time to touch the floor, but change the real time dt=5ms,less than 1s i...
