The design of the buggy was good and unique in the fact that it was Lego with a acrylic base for reinforcement. It was suited for the task but could have been improved in the following ways:
1. The Lego could have been glued together to prevent breakages when the buggy was running.
2. The circuitry could have been built on strip board or PCB (printed circuit board) this would have reduced the size of the buggy, which would make it lighter.
3. The variable resistors could have been mounted on the top of the buggy in order to make tuning the circuitry to follow the lines easier.
4. A cover could have been built in order to cover all the electronic parts using Lego doors in order to access switches and battery compartments.
5. The trolley wheel could have had a better design as it did not suit its purpose and would not swivel as intended causing the buggy to deviate from its intended route.
Overall we believe the design was good and was easy to adapt due to the fact that it was Lego and if something didn’t fit it could be rearranged in order to fit it in, allowing from extensive development during testing.
The physical structure of the design seemed fine but there were obviously issues with the software, sensing or actuators. Any feedback on what went wrong here ?
