Hi! Our names are Daniel and Brendan. We are taking an after school Lego class at Vina Danks Middle School in Ontario, California. We are building with Legos and programming them with the Logo software that comes with the Control Lab Lego kits. The kit had building instruction booklets for many different projects. We chose to do the wheelchair project and followed the step by step instructions in the booklet. We only had a few problems such as trying to find the correct parts such as the 4 x 4 parts. There were also small parts that we couldn't find like the 1 x 2. Those are really small but quite important. To solve this problem, we found the parts we needed in a spare parts box. The other problem was that the wheel kept on slipping so Brendan thought we should take the wheels off and used the gears that connected the main axle to the motor worm gear as the wheels. The teeth of the gears gave the wheelchair more traction and speed on the carpet. We were having a contest against the other two kids in our class, to see who could make the wheelchair and joystick the fastest. We won because they had to find many more parts than we had to. After building the wheelchair and joystick, we had to type in the program to make them work. You can see the procedures we typed below the picture of the wheelchair. That is what we did on the first two days of the project.
Link to the third day and the wheelchair with tank tracks.
Below is a picture of the Lego project and the procedures.
