How can I use joint to realize a bend movement ?

[jianye]

hello,

i want to know how can i use the JOINT to realize a bend movement ?

i want build a person model that it can bend forwards about 15 degree and after that it bends back.
I set the joint as the motor and I use the function sim.setJointPosition(), but unfortunately it didn't work.
I have seen the model walking_Bill but i don't know how this function is realized.

Which Function should I also use or do you have a similar model that i can learn from ?

Hello,

if the joint in motor mode you should use sim.setJointTargetPosition rather than sim.setJointPosition.

hello,

Thank you for your reply.

i set the joint in Inverse kinematics Mode, and i don't how to let joint to form a bend movement.

Can you give me some advice? Or do you have similar model?

Hello Jian,

this really depends on what kind of model you have ... is it dynamically enabled? Is it controlled via IK? Or is it a static model where you can instantly adjust joints?

Cheers

Why would you want to manually move a joint in IK mode?

hello,

i am sorry that i didn't explain my problem clearly.

in fact i want to control joint via IK. I want to accomplish the function like Walking Bill.ttm in Vrep that the body can forwards bend.

thank you

Walking Bill.ttm moves only by pure forward kinematics, using sim.setObjectPosition and sim.setJointPosition.
