# Controlling the robot with joystick values [closed]

I struggling days with this problem :

I have joystick values 0~FF for each axis. So the higher this value, the faster the axis moves. I am trying to find a way to control a robot with these values.

For instance:

The 1. axis of the robot should move 50 cm into z-direction. For this experiment there is not any feedback system from the robot. So we dont know how much the robot has moved with each joystick values. Will there be a solution for this given circumstance?

At first, I tried to solve this problem with a simulation model. After building a robot model, I could calculate the desired joint angle value changes for each axis with a IK solver. Then again, the problem is to convert the calculated joint angle value changes into joystick values. Since the robot is controlled with this values.

• how do you control the robot now? .... it seems that your question has nothing to do with a joystick, and it has everything to do with controlling a robot Nov 3 '18 at 23:32
• Right now, I am controlling the robot with my joystick. And I want to replace this joysitck with my laptop. My question here is how I can controll the robot with these joystick values.

• that does not clearly explain how you are controlling the robot ..... how is the joystick connected? Nov 4 '18 at 17:02
• How many joints in your robot arm, and what is the arrangement?

• How is your system currently providing feedback on whether you have moved 50cm in the right direction or not? Pretty much every robotic system needs a feedback mechanism, and I'm would guess that you are the feedback mechanism. Nov 5 '18 at 18:09
