Conclusion

So far we can conclude that the system is able to maintain air pressure at the required range. The compressor is capable of supplying the pressure we need at a reasonable flow rate and the tank/flow loop is capable of holding more than enough pressure. The arm and fingers have yet to be fully tested but they are currently functional. The chassis is being built and would soon be ready for testing.
