[Please read carefully before buying]

Robot parameters:​

Mobile phone: Android5.0 or above, screen resolution of 1080P or above (currently mainstream mobile phone basically reach, temporarily do not support s).​

Communication mode: Connect the same router or robot to the hot spot of the phone (the phone should have Bluetooth function at the same time)​

Communication distance: ① The hotspot mode depends on the iFi power of the mobile phone, and the non-blocking router mode depends on WiFi about 30-50m​

Coverage area: in the office building with good coverage, distance can be ignored if the network is unobstructed.​

Battery and endurance: the battery is 3.7V lithium battery, the capacity is 200mAH, a charge continuous use time of about half an hour​

Driving speed: 5cm per second (adjustable)​

Light brightness: stepless adjustable.​

Body material: plastic, metal, PCB​

Exterior dimensions: length 56MMx width 45MMx height 61MM.​

Accessories: robot + data cable + charging & communication board + packaging box.​

I actually have one of these things. It gets you thinking about how much transport we actually need. The top speed is pretty good considering how tiny the panel is.

How steep a "hill" will it go up?

 

[amberwolf]

FWIW, most of these tiny things I'm finding by looking for stuff for the Snuggles the Wolf robotics project, just checking out what kinds of really tiny actuators are out there that I might be able to use for subtle facial expressions.

(since the head still has to be huggable and kinda squishable, it can't be made the typical way for such things, so I'm looking at all these little things and other stuff including just plain magnets and coils, and NiTi wire, etc., to see what my weird brain comes up with later; might take weeks or months but ideas will pop out that might be adaptable to reality).

What? you don;t want to have a teddy ruxpin horror story told of your creation?

For anyone who is confused about what I am going on about, you need to look this stuff up for yourself, I am *NOT* gonna be responsible for your nightmares.
