techpod 2.0 progress blog
This is my official blog for the progress on the techpod 2.0 . I have posted some design pictures here . this is the first try at a frame for it .clearance between camera and dome look great no problem getting 180 deg of travel on both axis . the only problem is the servo proves be to wobbly by itself so I'm going to whip up a solution . I have the new design just gotta go cut it out in the CNC . will post the results . you can learn more about the techpod and purchase the 1.0 version at evuas.com .

Can you give us some specs? Camera, servo (360deg or?) Source for dome and its size?

@ ken
sony fcb-ex11d , servos = hitec hs-5055mg . dome is 4 inch acrylic .360 would be nice but aside from custom actuators there is really not any choice . sure you can mechanically get 360 from these servos but you will also half you resolution . resolution is very important due to high zoom .

What kind of vibration do you see with the thin member that connects the camera to the body? Have you thought about turning that into a torque box or using stringers to reinforce it?

problem is 360 degree servos like you show don't have any positioning the stick only controls the speed of the rotation, not the position .

front revamped to include "swash plate" and stabilizers to keep the whole thing stable .

Please don't be fooled by continuous servos, its very very easy to modify a standard servo for continuous rotation! don't pay crooks to ridicule you!
also, nice pan tilt thing u got going on! i'm working on one too, making it able to point at any GPS location you give it. in fact i've done more code than i have hardware :D
love the techpod!

What kind of interface do you use between the camera and computer?
