Introduction
The HAN-AR have two model based development tools, HANcoder and HANtune, that they would like to promote. In order to do this a new demonstration model was required. This is what the project team Highway Surfer has created. The model will showcase the abilities of the tools and will act as an eye catcher at tech fairs and conferences that the HAN-AR attends. With the help of this document people who are interested in recreating this project or start their own projects will be able to see what the steps involved are, the materials required and the capabilities of the tools, HANcoder and HANtune.
This project was started with the help a template. This template can be downloaded from the following link:
On this wikipage, you can find the building process for the mechanical parts, the wiring and other processes for the electronics, and the logic for building the software algorithm. To make it easy for the consumer, we have an easy to understand order list with relevant links.
Materials Required
In the Appendix, a detailed order list has been attached. However, a simple list is added in each subchapter to tender to specific parts.

HANcoder and HANtune are available at OpenMBD. (On the website is a download manual for all the software.)
Mechanical
For the mechanical design the dimensions can be found in the CAD 2D drawings, which can be downloaded from the website [link here]. When all the parts are cut, they can be assembled. In the exploded views in this document the exact order of assembly is explained.
Conveyor belt base
Housing
To build the housing of the conveyor belt you need following items:
- 3x multiplex plates of 1220x610mm with a thickness of 5,5 [mm].
- Blueprints of the individual panels for the dimensions.
- Saw or something to cut the wood.
- Bolts(m5)
- L-profile(3000x20x20 [mm])
- Measuring tape
- Wood drill
Cutting
To get the right dimensions for this DEMO a LaserPro X500 was used which can be seen in figure 1.
The Solid Works drawings of all the wooden parts are send to a device that runs 'Corel Draw X8' which can be seen in figure 2.
The process can be seen in Figure 3. We chose this option to get a cleaner finish. Of course, there are other ways to get the panels to the right dimensions.
L-profile’s and drilling
The following L-profiles need to be cut- 2x540mm 5 holes per plane
- 4x100mm 2 holes per plane
- 2x460mm 3 holes per plane
- 10x50mm 2 holes per plane
Some holes need to be drilled in the L-profiles to match the bolts, for this DEMO 5mm. Be aware that the holes in the two planes are not on top of each other, see figure 4.
Assembling
Place the plates with the L-profile against each other and mark the holes.
Do not forget witch L-profile you use, every profile is slightly different even with the best measurements.
Continue by drilling the marked holes in the wood and assemble the parts with bolts and nuts. Start from the bottom and work all the way up.
