The B.E.A.M robot concept was coined by Mark Tilden which inspired me to build this robot.
This robot is based on a circuit design created by Manfred Schaffran.
I've simply shrunk it down as small as I can to create this little B.E.A.M robot.
It's self sufficient and light seeking, so it can be left to it's own adventures.
Step 1: The Circuit
Step 2: Part List
4x 1000uf TANT SMT cap (T495X108K006AT)
2x TLC555 IC
2x BSR14 (2N222 transistors)
2x SMT Photodiodes (BPW34S)
Solar cell (Powerfilm)
2x Hubsan quadcopter motors
Step 3: How It Works
The solar cell charges the caps and the power turns on one of the 555's motors depending on what photodiode has the most light on it, effectively making the robot light seeking!
