We have an application of Robotic platform.
We have laser range finder to take map and detect obstacles and encoder to take reading of motors by combining we calculate x,y, z location of robot into the perticular area.
We have indoor robot application. Now we are facing a problem where we have limited range of sensor laser (ladar ) that is 5.6 mtrs. and have little difference between two motor rpms. We want to reduce this error and make robot more effective in localization.
I heard about the sensor Gyroscope-IMU. I have basic questions regarding the same as below.
1. How it helps to find a position of a Robot?
2. We use PIC controller to drive a motor and PIC is connected to our main board where Robot software is loaded and LADAR is connected. How can we implement IMU to fuse with these two sensors?
3. How much it is effective? and which is the best module available in the market?
Hope to get some idea about it.
Thanks a lot in advance.
