Making a 4-Legged Robot Ball

This is the build video of 4B, a robot i started working on last year but had to stop because of the other projects that I had. This robot has 4-legs with a total of 12DOF, and what's special about it is that it can fold in a 6cm diameter ball!

What I'd suggest is modifying the protection circuit to allot for a slightly higher current draw for 4B to fully function. And to still protect the battery.

this would be interesting to revist and add "morphing" legs ...using the same tech used to make morphing wing trailing edge ...it would allow each leg to "stretch"

[@sidyajv]

Superb

[@JoeErndtSEO]

Hello can you explain the math you used to figure out the acceptable weight? You mentioned the length of the leg and the torque of the motor. What is the formula? Do you have any reference you could share as I am trying to figure out what motors will be best for a project. Thanks

Yes it was (I graduated in 2016) I 'm glad you liked the montage, its an honour to be compared to a neistat edit

The surge current of the servos might be exceeding the limits of the battery.
