| And in this case, I think it would be parallel to the shin and
| foot. The "thigh" would be the thing that has the name of the
| school, the knee would be where that meets up with the long
| orange bit, the ankle is the joint where the two bars meet,
| then foot, and toe.
|
| Birds are weird. Or we're weird and birds are normal.

| motor. This reduces the torque required to move each section of
| the leg, which in turn allows for smaller motors to be used,
| which further drives down the torque requirement.

| The battery is good for about 20-30km range which really
| surprised me. So for this robot maybe not as efficient as 2
| wheels but I would guess it wouldn't be hard to get a range of
| 10-20km quite easily with today's current battery tech.

| Ostrich's top speed is ~40mph, easily beats Usain Bolt :)

|
| Seems like it all works out.

| Pretty amazing stuff, even if it's still slower than my grandma

| Are you sure? https://world-masters-athletics.com/wp-
| content/uploads/2022/..., page 18 shows a 60 year old female
| competitor clocking 23.15s over 100m, so I would think most 60+
| year old women would be slower than that, and the median
| grandma that runs the 100m faster than this robot would be
| slower than this robot.

|
| Everything is software bound.
|
| *edit, I think it just runs like a grad student.
