Calculate physical speed constraints on the robot

[coderabbitai]

Description

We need to calculate the actual physical speed constraints of the robot by measuring performance on the real hardware.

Measurements needed

• Maximum linear velocity (currently MAX_SPEED in PhysicalConstants.kt)
• Maximum linear acceleration (currently MAX_ACCELERATION in PhysicalConstants.kt)
• Maximum angular velocity (recently increased from 180 to 360 degrees/second)
• Maximum angular acceleration

Background

Currently, some of these values may be theoretical rather than empirical. The PhysicalConstants.kt file contains a todo comment:

todo: should we calculate these values or see what they are in practice? (probably see)

This issue was requested by @Baconing in PR #21.

Suggested approach

1. Devise a testing methodology for each constraint
2. Perform measurements on the physical robot
3. Update PhysicalConstants.kt with the empirical values
4. Document the testing methodology for future reference
