| 1 |
Add side rollers to guide
the vehicle on track |
| 2 |
Ensure that the vehicle
must be stable and all wheels are well aligned |
| 3 |
Reduce friction on all
moving parts |
| 4 |
Gears must be properly
meshed |
| 5 |
Chassis of the vehicle
should be in aerodynamic design to reduce air resistance |
| 6 |
Use rubber bands or a
section of a balloon as tyres
of the driving wheels to improve grip on the floor surface |
| 7 |
Must be easy to maintain,
for examples: changing of batteries, replacing damaged parts, etc. |

Overall vehicle size must
be within specifications if you are entering a competition |

 Practical
Hands-on tips to make a better model & improve the performance of your
model.
|
|
!! |
Before you start to assemble
your models, identify all the parts from your kit set. Do not use the wrong parts.
|
|
1. |
To glue wood, paper or textile, use only good quality
glue. (for example, our PVA white glue).
Apply evenly on the surface. |
|
2. |
You only need to use a small amount of PVA white glue to
join materials together. |
|
3. |
To stick plastic sheet and wood, use thin double-sided
tape |
|
4. |
For some models, the gear or pulley must be tightly fitted to
the dowel so that the gear of pulley will turn when the axle turns.
(Ask for adult help, apply a small amount of super glue to
the pulley or gear.)
|
|
5.
|
To help ease dowel in to the centre of a tight wheel, use
sand paper to sand the edge of the dowel.
|
|
6.
|
If plastic wheel (e.g. for Moon Rover, etc.) is too loose,
use transparent tape to tape around the plastic tubing and push in to the plastic
wheel.
|
|
7.
|
Wooden wheel must be tightly fitted to the dowel so that
the wheel will turn when the axle turns. Use PVA glue to stick the dowel to
the wheel if the wheel is too loose.
|
|
8. |
Do not push the wheels too close to the model frame. This
will increase the friction and reduce the speed of the motor. |
|
9.
|
Use hot glue or epoxy to strengthen your models.
|
|
10. |
Add rubber band on the wheel to improve the grip on the
floor. |
|
11. |
To avoid short circuit, tape all exposed wires with
insulation tape (or normal transparent tape). |
|
12. |
Do not let the switch remain on when the motor is not
running or the model is not moving. |
|
13. |
Use alkaline batteries for more power. |
|
14. |
To increase the speed of your motor, connect it to 4.5V
supply. Most of our motors can operate up to 4.5V (3 normal 1.5V batteries
connected in series). |
|
15. |
For Light Chaser Robot, change gear ratio to faster speed
and supply to 6V (4 AA size batteries).
The respond and speed of this robot will become faster. |
|
16. |
For Line Orbiter Robot, try to increase supply to 4.5V (3
AA size batteries) to increase the moving speed.
(Note : this robot cannot move too fast, otherwise it will go out of
control) |
|
17. |
The best way to improve your
model making skills is to attend our Dr. Dino
Hands-on workshops. |
