Teleteddy in the making
To make each Teleteddy, I wired 7 force sensitive resistors (FSRs) throughout the bear (1 in each leg, foot, ear, and another one in the tag on the rear of the bear). All of these FSRs were connected to an Arduino Uno. In addition, we wired a Flora RGB LED to each FSR (excluding the one in the tag) and we also strung 4 Flora’s next to each other to be placed where the teddy’s heart is. We also use Zigbee radios for the wireless interconnect.
To place the electronics in the bear, we had to open them up, remove the stuffing, and gently place all the wiring within the bear. After the wiring is placed within the bear, most of the stuffing is re-added. (Note: an inside-out teddy bear looks pretty creepy)
For this project, we were constrained to use the Arduino UNO which would not fit inside the bear so we left it hanging on the outside.
To enable a “game mode” between the connected bears, we placed an FSR where the bear’s tag is.
