Robot Nao is based on a 500 MHz AMD Geode CPU running Linux and implementing dsPIC Microcontrollers for motor control. Programmable in C, C++, Urbi and Python. Ethernet (in the back of the head) and WiFi are supported on board.
High level control and simulation via Aldebaran Choregraphe, Microsoft Robotics Studio, and other software.
The Johnson Bar or J-Bar is probably my favorite tool ever, it has been said that its mother was a hand truck and that its father was a lever. The Johnson Bar provides both a lever and a fulcrum in a convenient wheelie package. I suggest the 7 foot length for maximum leverage.
R is for Resistor C is for Capacitor L is for Inductor D is for Diode F is for Fuse Y is for Crystal... Wait, what!?
In another case of not being able to google find something if you don't know what it is called; if you are trying to figure out if Q3 is a transistor or a diode or an IC, then you need to look at its reference designator.
This looks like it would be useful when you need to connect your waterproof ground robot or AUV to the network for upgrades. There is no retention clip on the waterproof side, it is held in by the screw cover. I may end up using this one as a cisco style serial port.
This battery provides a drop in replacement for a regular 9 Volt battery and only weighs 23 grams when empty.
One downside however is that lithium polymer batteries are slightly temperamental. If the batter puffs up or appears bloated you should stop charging and properly recycle the battery as it is dead. You should only use a charger designed for lithium Polymer batteries, and preferably one with a built in cell balancer.
These cells are bloated and are now a fire hazard as lithium tends to react violently with air.
So each cell in the battery provides 3.7V and 380mAh but somehow the battery provides 9V and 450mAh. This is the power of Revolution Technology!
Actual specs are closer 8.4V peak voltage and 380mAh. I think the revolution has problems accurately rounding. On the upside your microcontroller's voltage regulator won't care that it is not getting 9 Volts.
I tried using wire wrap receptacles for an Arduino daughterboard and found that the insertion force was way too high for reliable usage. The alternative I found is Samtech Part numbers ESQ-108-14-T-S and ESQ-106-14-T-S. Unfortunately, only Arrow seems to stock them. Perhaps I'll carry them when I get the online store up and running.
These connectors work much better then the wirewrap sockets.
