4. PORTFOLIO
DELTA ROBOT
This delta robot is made by NTUST Medical Robot
Laboratory Students for Delta Robot Competition
held in National Taiwan University in 2014. This
robot is actuated with 3 HIWIN AC motors to
move the end effector in 3D space, and
controlled using ARM STM32 Microcontroller. The
competition goal were to do the stamping as
many as the robot can, and also pick an object,
and move it along the trajectory which is decided
by the competition rule. This robot won the 1st
place of freshman category. The honor is posted
in front of Electrical and Electronic Engineering
building in NTUST.
TEEN-SIZE HUMANOID
The goal for the project was to create the teen
size humanoid robot which be able to walk, fall
down and stand up. This robot also can play
soccer. To achieve this goal, vision detection is
utilized to recognize the ball, and also make
decision about where to move the detected ball.
My part was to utilize the locomotion control so
that robot can walk. We used LIPM concept for
Hip trajectory and also maintain the robotβs
CoG(center of gravity). AHRS sensor was used
for robot walking stabilization, and also fall
detection to perform stand up procedure.
EXOSKELETON
My part of this project will be the leg control
using Regressor Free Adaptive Impedance
control as the compliance control, so that
the robot will be able to adapt based on
patient leg movement, and also Disturbance
observer to estimate external torque and
amplify it for the passive power assisted
exoskeleton.

3. ACCELEROMETER + GYROSCOPE +
MAGNETOMETER outputs will be
calculated using Direction Cosine
Matrix to reject noise and drift from
those sensors and forming 9 x 9
orientation matrix so the roll pitch
and yaw output could be obtained.
4. PID output will be the input for
brushless DC motors
5. Attitude data will be sent through
xbee for analyzing

HOW IT WORKS
ACTIVE-ASSISTED EXOSKELETON
1. Exoskeleton will move based on the certain
trajectory, and the patient leg will follow the
movement.
2. The motor position and velocity will be sent
through serial communication from the motor
to microcontroller and control it using
ADAPTIVE CONTROL to follow the trajectory.
3. This control requires NO ACCELERATION
FEEDBACK and SYSTEM DYNAMIC
PASSIVE-ASSISTED EXOSKELETON
1. Position and Velocity from the motor will be red
as the input to measure external torque using
DISTURBANCE OBSERVER
2. The system will amplify the torque estimated to
assist the patient movement
3. Gravity compensation is needed to get rid of
gravity effect

on the competition rule
2. Air gripper is used to grab
objects and move it to
certain position
3. Delta robot inverse kinematic
is used to get the desired
rotational position for 3 main
actuators
4. We used default PID position
control from motor driver
5. Communication from
microcontroller to AC Servo
motor driver is based on
pulse counter for desired
rotational position and pulse
frequency for the desired
speed.

HOW IT WORKS
1. LIPM is used to create the hip trajectory when
the robot perform omni-directional movement
2. Besides LIPM we also create foot trajectory.
Together with LIPM trajectory output, we
calculate the robot inverse kinematic to get
motor rotational position of Robotβs leg.
3. MX-106 dynamixel motor has its own PID control
for motor rotational position control.
4. Gyroscope is used to read and use PD control
stabilize the robot walking.
5. Using DCM algorithm, we calculate the robot
orientations and use them to detect whether the
robot falls down or still walking and perform
safety fall then stand up procedure if the robot
falls.
6. Using DCM, we can know robot position relative
to north direction, and we will use that
orientation to define the goalpost in soccer
competition.
