Are there any constraints on the dimensions of the robot? I am currently using 4 of the 18" (45cm) C-Channels to form the outer boundaries of the robot, on the outside of which I will add 4 wheels? Would that be legal?

Friendly reminder: Almost all of the questions you have can be answered by going through the rule book for the game, including sizing for robots.
The max size a robot can be for inspection is 18" by 18" by 18". Be sure to check the rule book before posting questions next time.
From the Turning Point PDF rules, from R1:
<R1> Only one (1) robot will be allowed to compete per team in the VEX Robotics Competition. Though it is expected that teams will make changes to their robot at the competition, a team is limited to only one (1) robot. As such, a VEX robot, for the purposes of the VEX Robotics Competition, has the following subsystems:
Subsystem 1: Mobile robotic base including wheels, tracks, legs, or any other mechanism that allows the robot to navigate the majority of the flat playing field surface. For a stationary robot, the robotic base without wheels would be considered Subsystem 1.
Subsystem 2: Power and control system that includes a legal VEX battery, a legal VEX control system, and associated motors for the mobile robotic base.
Subsystem 3: Additional mechanisms (and associated motors) that allow manipulation of game objects or navigation of field obstacles.
Essentially anything that is on your robot is part of that limit.
@meng And including the zip ties and screws or nuts that might be sticking out...
I remember in Starstruck early season we had gone for a high hang and one of the zipties for routing wiring was sticking downwards (we had an elevator-style high hang), taking away the high hang status... I've hated size constraints ever since.
In addition to the points above about no parts being outside the cube, I would also note that you don't have 18" C-channel. 35 holes is 34 X 1/2" space between their centers. Then you have another 1/4" at each end. That's 17.5", which is handy since the smallest bending outward of any sort or smallest deviation from 90 degrees at the corners would make an 18"x18" theoretical, horizontal square be illegal.
@TitansRoboticsB I don’t think you understood my question
Do my wheels count as part of the 18 by 18 by 18 limit
Your wheels are part of the robot, so yes they count as part of the 18 by 18 by 18 limit. NO part of your robot can extend outside of that limit at the start of the match. As others have mentioned, please obtain and read the Game Manual, that will answer a LOT of your questons.
