humanoid robot
Humanoids can communicate in a manner that supports the
natural communication modalities of humans. Examples include:
facial expression.
byrun Byrun is a dynamic humanoid robot able to walk , run, jump, with facial
expressions, voice & gestures.
Technologies used in byrun
Parallel electro- pneumatic actuation.
Expressive head.
Bi-articulated limbs.
Tactile pneumatic hands.
Custom built BLDC motors.
Precision encoders.
Energy storage via muscles.
Ground contact sensing.
Series –elastic actuators.
Design principles
Byrun has a bio-mimetically driven design rationale. Namely,
to emulate human movement and dynamics.
Byrun’s proportions, joint locations and actuation ranges are
as closely matched to a human model as possible
Kinematics
Bi-articulate actuation: motors and pneumatic muscles that affect two
degrees of freedom simultaneously.
. In the legs the actuator linkage mimics the action of human muscle pair
rectus femoris and biceps femoris.
Series & parallel elastic elements :These are used to sense force energy,
counter gravity loads which can reduce power consumption and required
maximum output power
Multiple Actuation Types: the human body has at least four muscle types,
with skeletal muscle dividing broadly into two variants, fast and slow
twitch.
motion of byrun
Walking is not merely a
means of locomotion.
It can also act as
multivariate signaling
device.
We envision a robot who
can spring optimistically
into action, run across a
room.
Expression Byrun is not just a mobile set of limbs, a robot who can read your facial
expressions and body language, and modify their own.
Projective head technology: Byrun’s head shape has designed to be
androgynous - combined with our projective head technology, Byrun can
take on the appearance of anyone
Actuators in byrun robot
Brushless dc motors.
Brushed dc motors.
Ball screws .
Pneumatic muscles.

Using MapleSim, Byrun's designers and engineers have developed a
biologically analogous leg design which will give Byrun the ability to
walk, run, jump and hop
advantages of byrun robot
Human interaction.
Human work becomes easy.
Can run , jump, hop
disadvantages
Technologies are complex.
Cost is high.
Controlling could be corrupted.
Applications Security purpose.
Terminator biped.
Receptionist.
Entertainment
conclusion
Byrun are setting a new standard for robots.
Byrun will make a great platform for others to
build on.
Byrun can perform something never seen before
