I've finally managed to model something that I came up with when I was 5 years old!
The robot's general design was to basically have a camera in a small or dangerous place, be it a robotic exploration of a planet or spying Soviet militarists. It's basically a tiny Autobot; it can be its quadrupedal form or retract into a ball when asleep or threatened. This particular model has many interesting features. This extremely expensive yet sturdy machine's mechanical prototypes started as the size of a baseball before it's pea-sized consumer products. When retracted into spherical form, its reinforced steel is strong enough to withstand 4000 kg of weight. At this form it is also waterproof to depths of 30m. It's heatproof shielding can stand about 900 degrees F. It's tiny camera is about 4 megapixels of colored (or cheaper colorless) footage of 10 frames per second as well as a simple microphone. The camera can rotate 70 degrees vertically both ways. Horizontal rtation is done by the legs. When expanded, it unfolds its geared internal carbon legs. which allows it to walk at about 1 cm per second, moving one leg at a time. Unfortunately, the mechanics of the legs cannot lift any more than 3 times ti robot's weight, so it cannot break its fall. So it's built sock-resistant of up to 5 m. Since it's about the size of an airsoft BB, there isn't enough room for any AI inside the machine. So it gets its thinking and power from a satellite. The satellite can process information to and from the Spheroid so it can tell it to retract if the Spheroid records danger to the satellite. Its almost seamless retraction makes it nearly impossible to be pried open. Internal locks keep enemies with tools from unscrewing to side caps off. All this is why the spheroid can cost up to US$2 Million per unit in addition to software to communicate with the satellite, which still needs permission from the government, an precision construction of each individual Spheroid.
Early concepts had segments of the shell as part of the legs, which caused the Spheroid to jam upon retraction if the legs were scratched. They also had a tiny gun to shoot a small, hot, painful spark to buy time for an escape, but would lead to the robot's overheating, and time was spent getting the gun charged --- which also drained energy.
