Budget 8 11 4

The maximum allocated budget from the Cambridge University Engineering Department (CUED) is £100 per student, giving £200 for the Robotic Unicycle. As expected, the project has now consumed this allowance and there is limited extra funding available from the Engineering Department.

Planned Expenditure

There remains a substantial number of components that are required for the Robotic Unicycle, mainly for the system electronics and control. The table below attempts to list these components but there may be changes to the plan as the project develops. An approximate date on which the components will be needed has also been shown to allow for some financial planning.
