Errors when using fingertip_pressure

No Data From Sensors

Use rostopic to check if the sensors are properly publishing data.

rostopic echo pressure/r_gripper_motor

If the data for pressure contains only "0" or "-1" values, then the tip sensors are not properly hooked up. You'll need to check your connections.

No Data Displayed By Visual Tools

The visual tools in this package always look for messages on the right gripper motor. If you are looking for data from the left gripper, you will have to remap the topics.

You can check if the topic is properly remapped by running "rosnode info" on the viewer, or "rostopic info" on the topic.
