Normalizing image data before training - GRU version
Testing image normalization when using a GRU.
Normalizing image data before training - LSTM version
Testing image normalization when using an LSTM.
Normalizing image data before training
I had completely forgotten to normalize the images I’m feeding into MaLPi’s network, so I thought I’d try to be a bit more formal about it than my usual.
Getting a Keras LSTM layer to work on MaLPi
Training on batch sizes and/or sequence lengths longer than one, while still being able to run one image at a time on the robot.
Experimenting with OpenAIs Baselines code
I forked Open AI’s baseline code and made a few changes. This was my first full run before I started playing around with the model architecture.
Single Battery
Eliminated a battery! (maybe)

State of the Hardware v2
I’m about to make large changes to MaLPi so I wanted to document the current state of the hardware.

Motors
What have I gotten myself into?!?! Motors and controllers and a breadboard, oh my!
Lego Chassis
Some progress on the hardware front.
Endurance Test
Test how long the PowerGen battery can run MaLPi on a single charge.
