Robot Arm Projects

Our robot arm project started in 2018.

We are now creating small robotic arms as a test project to animate the arms of a teddy bear.

The First Version.

It used three servos, but it was too noisy.

The Second Version.

To reduce noise I tried using stepper motors, but it didn't work well due to heat buildup. After 3 weeks it stopped running so we decided to use servos again.

The Third Version (Top Video)

Using five servos.

Installation was just about completed, but we discovered that the cable broke after only one day of operation. So now we use strong stainless steel cables.

Beyerdynamic T5p Cable Replacement Solution

We decided to add MMCX female connectors to our T5p headphones to allow for easy cable replacement / upgrade with any MMCX male cables. First, remove the original cables. MMCX female connectors I got these connectors in Japan, but I was able to find them on Google too. Push in the connector into the 3D printed parts. You can download the files for the parts we 3D printed here . The parts were a perfect fit when printed on our 3D printer, but it may defer depending on the 3D printer. Then I cut the original cable to create two short cables and soldered them onto the connectors. The middle prong is for the red wire, and then as for the outside prongs, you can pick one for the ground. After they're connected, you can secure them in place with some hot glue. In the picture below, the cover parts are put on, but those can not be on when you insert the part into the headphones in the next step. Then insert this part from the outs...

NFC + Timesheet App

We're now using NFC technology with our timesheet system! We have implemented the NFC technology into our timesheet system making it easier and simpler for our friends in the office to log in and logout of the system. Using this new system, we no longer have to go on our computer and open the web app to start logging the time anytime, because we can just open our iPhone app and scan the NFC tag on the office entrance on our way in in the morning. The video below is of our NFC implemented system in our office that is already in use.

Adjustable Monitor Mount for the Leap Motion Controller

We worked on a new casing for the Leap Motion Controller. We thought, "What if we were to put the Leap Motion Controller on the monitor, with a secure mount?" Check out the pictures below for the result. Concept Art Actual Case: We settled for flat surface due to client's request. Two screws are holding the case from behind. These screws allows you to adjust the arm to desired length so that this case will fit most models. The mount is pretty tight and it cannot be removed that easily. Perhaps for the public kiosk use?
