1. Design of a Hexapod Robot
Abstract:
This paper introduces a new hexapod legged robot that can autonomously adapt to
a variety of terrain; its wheel leg designs specially to make it have a good obstacle
surmounting capacity. This robot uses the modularized design method, using the interrupt
to detect the position of the wheel leg, PWM to control motor speed, Bus to control
motor, gait program to control the robot motion, wireless data transmission to control the
robot's gait, host computer to real-time monitor the robot status. The host computer or
user handheld devices can regulate the state of the robot, at the same time the host
computer can monitor the state of the robot. Finally, the principle demonstrator verifies
the feasibility of the software design and hardware design method, thus ensuring the
validity and reliability of the robot design.
Existing System:
There are many places cannot be reached by wheeled or crawler walking
mechanism that are widely used now, but the multi-legged animals in these place move
freely. Wheeled mechanisms used nowadays cannot move on irregular terrains.
Proposed System:
The hexapod robot has the control module and the robot body. The host computer
and the handheld control device constitute the control module. The robot body has the
moving mechanism and the control circuit. We can use the host computer or hand-held
control device to complete controlling the moving of the robot. It can control the robot
moving forward, moving backward and turning around. The robot has the six same
eccentric legs. Each leg is drove by the same geared motor. The robot is controlled
through Zigbee from remote PC. The robot is characterized by: the symmetric simple
mechanical structure, high reliability, good stability, more obstacle surmounting capacity.
The eccentric-type legs have more flexible than the traditional rod-shaped legs, more
adaptable to the ground. It not only can move on the smooth hard surface but also can
move on the grass, sand, and gravel ground.
