Humanoid/Bipad Robot

 The Humanoid/Biped BRAT Robot

humanoid robot is a robot with its body shape built to resemble the human body. The design may be for functional purposes, such as interacting with human tools and environments, for experimental purposes, such as the study of al locomotion, or for other purposes. In general, humanoid robots have a torso, a head, two arms, and two legs, though some forms of humanoid robots may model only part of the body, for example, from the waist up. Some humanoid robot also have heads designed to replicate human facial features such as eyes and mouths. Androids are humanoid robots built to aesthetically resemble humans.



 The Lynxmotion  Biped BRAT
BRAT stands for Bipedal Robotic Articulating Transport. The robot is a 6 servo biped walker featuring three degrees of freedom (DOF) per leg. The robot can walk forward or backwards and turn in place left or right with variable speed. It can even do lots of Robo-One style acrobatic moves. Our combo kits include everything needed to make an operational robot, however the chassis and servos are available separately for those who want to use their own electronics.
The Mechanics
The robot is made exclusively from brushed, or black anodized aluminum servo brackets from our Servo Erector Set. It also includes an electronics carrier made from ultra-tough laser-cut Lexan.

The Servos
We are providing the walker with Hitec HS-422 servos. Due to the robot’s light weight, these servos work well.




The Lynxmotion Biped Pete


The Lynxmotion Pete humanoid biped robot is a 22 DoF R/C servo based biped walker with gripper hands as the default configuration. This enables Pete to walk forward or backwards, turn in place left or right with variable speed. The leg design is similar to that of a human.Several versions of Pete are available:

  • Hardware only: this includes only the brackets and hardware; no electronics or servos are included.
  • No electronics: this includes the complete frame and servos
  • No software: this includes the complete frame, servos and SSC-32 servo servo controller

Pete has five degrees of freedom per leg, five degrees of freedom per arm and two degrees of freedom in the head. It is important to note that at this time, Pete is a research platform and requires that the user create their own walking algorithm and complete the electronics for either remote controlled or autonomous functionality. 

The Mechanics
The robot is made from black anodized aluminum servo brackets (the images shown at right with brushed brackets are prototypes) and ultra-tough laser-cut Lexan structural components. Since the kit is based on the Servo Erector Set (S.E.S.), the parts can be easily used (in conjunction with a few other parts sold separately) to make a variety of other robots such as quadrupeds, hexapods, robot arms and more.

The Servos
The complete kit includes a variety of servos:

  • 14x Hitec HS-645 high-torque servos for the foot, ankle, knee, hip, “waist” and 2DoF shoulder.
  • 6x Hitec HS-422 servos for the wrist, gripper, neck and head and elbow
