Sensor and Sensitivity

hairygael's picture
Hello everyone! It's been months since I didn't log in to MRL shoutbox.
 
If I log it's because I need a little help on something that is frustrating me since last night.
I am designing a new hand with much better sensors and sensitivity. AH3503+ micro magnet 2x1mm

More progress for Fred

  So this is where Fred-X's belly is today. I am building a leg (left), so that I can measure the correct length for his new dolly. I have all the parts for the dolly, but I want fredto appear to be standing normally. The pipe on which his weight will be supported must bethe correct length, so once his leg is complete, I will remove his head and arms and covers etc and assemble the middle section and one leg  then measure the correct pipe length.

The dual motor controller is based around the Arduino Nano using PWM output to control up to two DC motors and one standard type servo.

where to go next? (not MRL, only my robot)

Hi

Working on teaching my bot to move in front of an optical tag I run into the problem that seeing no tag at the current location - where to go to check from another spot in the room for the tag?

Hello fellow MRLians

Today I received a query from one of our newer members, but was unable to reply directly.
It occured to me, if one user has the question, then others may as well.

Below is the query and my attempt to answer it.

Fred's progress

Monday March 13 2018:

 I have nearly completed Fred's torso. All of the mechanical parts have been fitted and assembled. His servo sensor pots have been fitted and have extended wires to mate to the servos. Auxilary motors are prepped, tested and wired. They are ready to add to the servos. I have the servos in house and can modify them as soon as I get enough time to work on them.
