The robot in my scene costs about 1 to 2 seconds every step when it moves via joint command. The operating mechanism of my code is redis-b0-lua, the vrep lua sc...

How to send message quickly?

The API "sim.getVisionSensorDepthBuffer" return a table, when I set the visionsensor's resolution X/Y as 640/480, It seems too large to transmit via b0 or process locally.

How can I do with the table real time?

Waiting for you reply.
And thanks for you reply before.

Your sincerely,

I am developing an environment using vision sensor. But I cannot send the image information got by sim.getVisionSensorImage out via b0. My vision sensor's resolution X/Y is 640/480. Is it too large to transport? It will succeed when the parameter is 32/32. What method can I use to do with this probl...
