Robot prototype
I finally received my Speakjet from Sparkfun so I spent some time carefully soldering that together so I can get my bot speaking. Not as simple as I had hoped. I’m still building and testing the components to make sure they will all fit and work inside the robot. I prototyped a few different sets of eyes based on the input of my classmates. One option is to mount the LEDs externally in plastic caps and another is to enclose the LEDs in little fabric “dumplings” to stitch inside the head. Both options create a different effect so I’ll keep testing. Ultimately, I think I’ll commit to mounting the LED heart inside the robot – it gives off a nice glow behind the printed black fabric. The pulse sensor is still giving me a little trouble so I need to work on the mounting situation in the robot arm. After that… code, code, code…and more code.

Mike, if you are getting to much light “bleeding” from the eyes you can: 1) put a higher resistor on the LED so it’s more dim OR 2) make the dumpling smaller or 3) explore a way to stop light bleeding from the edges like a different dumpling material….?

Thanks Yury. Hope you are feeling better. After testing about 15 different eye configurations, I finally committed to using the clear caps on the outside with a higher transistor rating to dim the LEDs a bit. Using the LED dumplings inside the head produced a cool effect but after some user testing people preffered the look of the externally mounted eyes. I’m now trying to make a similar decision about internally or externally mounting the heart LEDs. I’ll bring my prototypes to class on Monday.
