The Formica Swarm Robots were introduced at 25c3 (Scalable Swarm Robotics, Google Video). Besides the PCBs the parts are all very common and therefore cheap and relatively easy to get.
- burned a voltagecontroller by mixing up GND and Vcharge
- motors are running!
- All Parts arrived!!
- Recommendation: Before soldering a Formica Robot I reccomend soldering somthing with less smd parts, e.g. a moodlamp.
- Instructions Hardware short - list of components, …
- Instruction Hardware detailed - elaborated instruction with pictures
- smd soldering - some notes
- Communication, programming via IR (also mutual updates)
- Other components: Reflectivity sensor, status LED, IR sensors also used as brightness sensors
- Independent charging with the cunducting feet/antennas
- Motors as used in mobile phones (fast…)
- one charge of the battery equals about 30 active minutes
- size ca. 30*30*20mm
- available for µc3 members: 25€/Piece
Building some robots and a charger. Some changes on the charger (less bouncing off).
Changes to the original PCB
- Replacing of the original charging contacts with screw terminals
- introducing a way to measure the voltage (voltage divider)
- Changing the size of the PCB to make room for the battery, the screw terminals
- Material for the wheels: friction fit, d=3.5mm
- Programming with the ez430…
Price calculation with sources
The robots will be available for 25€ /piece.
- Putting the robots together
- Comfortable way to flash them
- Charging station
