Research Experience
Final year project - Toward Robotic Dentistry: a Teleoperated Compact Robotic Manipulator
09/2018-present
Description: On top of the works of another FYP group last academic year and my RA project, a new version of prototype with expanded capabilities and specified functions to get closer to realistic applications has been developed.
Methodologies:
Actuation: steel threads were used as the actuators of robotic arm, so that motors could be detached from the arm structure and arranged somewhere else
Structural configuration: the link lengths and joint angle range were designed that were similar to human arm, which is asymmetric, in order that the robotic arm would theoretically be able to cover the working spaces of a real human arm
Control scheme: a haptic device was utilized as signal input equipment; inverse kinematics was solved by a personal computer; haptic device, PC and motor control board communicated through series port.
Prototyping: PLA 3D-printing was utilized on most of the parts; two parts carrying heavy load were ordered from external manufacturer, made with aluminum
Major deliverable:
A 6-DOF robotic manipulator prototype was built.
A paper based on this project has been submitted to IEEE-CYBER for review: Yufu Tao#, Tianyi Zhang#, Wenyutian Xu#, Ho-Yin Tsang, Jing Li, Zheng Wang*, “A Compact Asymmetrical Manipulator for Robotic Dentistry” (# co-first author, * corresponding author)
RA Experience-Research on a Dentistry Robotic Arm 06/2018-08/2018
Description: designed prototypes of a mechanism providing a double-eyed view with simple devices available on e-commerce websites
Duties:
Used SolidWorks to design the supporting structures which integrated purchased devices to provide a closeup view of inside mouths for the robotic arm operators, and created the prototype with 3D printer
Modified the prototype model to improve its structural stiffness
Robomaster 2018 Robotic Competition 07/2018
Description: designed a “hero” robot (fetch bullets, sort and supply bullets to its cannons, aim and shoot, move on the battle field, withstand crashes and strikes from four ground directions), and earned the 2nd Prize in International Regional Competition and 3rd Prize in Wild Card Competition
Duties:
Designed the overall layout of robot vehicle and assigned spaces on the robot vehicle to different sub-systems
Devised mechanical structures of the sub-systems (bullet box fetching sub-system, bullet sorting and supplying sub-system, chassis) on SolidWorks and tested prototypes
Improved sub-systems and integrated all sub-systems to form the whole robot vehicle based on the designs of chassis
Generated engineering drawings, manually processed parts and assembled them
Conducted the operator training sessions and made further slight and necessary modifications according to feedbacks from operators
Provided maintenance and on-site repairments to handle the battle damages
