Need Help With Ping))) Sensor and Gripper!!!!!!

HassanDude

Alright so my plan is fairly simple:

Starts with a remote
Boebot spins in a circle
Finds an object with the Ping))) Sensor
Goes to object
Picks it up with a gripper
Brings it back (by following a line)

So I've got the basic idea done, but I'm still confused about the Ping Sensor and gripper part. How do I get the sensor to pick up the object? And I have no idea how to code the gripper.

Can someone please help me with this?

Thank you!

First, the object would need to be fairly tall so that it extends upwards into the range of the Ping (higher than the gripper). Also, the ping has a fairly large angle of detection, so you may get a return off of it even when not pointing directly at it. You would need to turn the bot slowly and find where it appears closest. This may still not be very accurate and you may need to check again once you drive closer to it.

The Gripper is easy to use, you simply rotate a gripper to open and close it very similar to controlling the drive servos of your bot.

You have a nice plan of action, the next step is to get the equipment and begin testing to understand the operation and nuances of the devices, test some theories and begin working on the code to make it work.

There was someone else here trying to do the same thing perhaps you could search for that thread and get some ideas. He had some video on youtube about it.
