Legs and wheels
I've been a bit busy recently doing stuff over at www.914pcbots.com as I've established admin rights (for now...). Hopefuly whiteboxrobotics will deliver the first shipment of robots soon and then we'll have a full blown fan site. There are already 100's of registered users although most are 'lurking' for now. From the stats is looks like there are around 300 visits a day so it will be good once the product is available.
On top of that I've been thinking about creating a new android called 'Android X' as it will be the tenth and also matches the Website name of XRobots. Android 9 will probably be ok but I usualy get bored at this point in development and have better ideas.
I'd quite like to use actuators/motors on all the joints instead of having passive ankles because that's the hardest thing to work with. I'd also like propper knees again rather than my on-going parallel mechanism that I've used since android 3. I quite like the balsa wood construction but next time I'll use RE/RS540 motors and make my own gearboxes out of plastic gears, using skateboard wheel bearings for the output shafts. It will look a bit like the RoboOne robots that use R/C style servos but scaled up to about 4 feet / 1.5m tall.
