WEEK 5: STUDIO WORK

DATE: 14/08/08
TIME: 11.00-12.30PM
VENUE: C25-5051
Attendance: Absent: Yusof

1. Concept 1:
a. No extra mounting on the middle of the motor. Best to have 2 point restriction on the wheel only.
b. No oscillating due to suspension spring.
Ideal (additional )
c. Rack and pinion usage to replace the middle suspension mounting
d. Try to apply the concept used for arcade game motor simulator

2. Concept 2
a. Same problem with concept 1. Cannot use suspension due to oscillation.
b. Replace spring to actuators. 2 actuators used for roll. Remove spring.
c. Realize concept cannot be yaw. Motor tire need to be mounted on the platform. The platform is mounted onto another platform with bearing and shaft to allow yaw motion.
d. Yaw motion use wire and motor.

3. Concept 3
a. If suspension is replace with actuators, motor wont needed for yaw motion. Need a shaft in the middle of the platform for stability.

4. Concept 4
a. No mounting in the middle of motor. Change the fixed middle point to the front shaft.

Job separation
1. Fahmi and Yusof: Find a motor picture and label the dimension of the motorcycle. Honda C70
2. Hsiao Ling: Draw motor use solidwork. Find an example of motor solidwork online.
3. Kim Heng and Yap: concept re-evaluate and research
