Untethered Pneumatic Robot

Pneumatic rubber actuators have merits such as high compliance, simplicity of miniaturization and light-weight however they also have demerits such as need for compressors and air tubes. We have been developing compressor-less pneumatic actuators which are driven by reversible chemical reaction instead of using compressor. This robot has three bellows arm that can be actuated up and down using the reversible chemical reaction.

This is really great! Love that the video is in realtime (unlike many other 'famous' soft robots), and it can also be actuated repeatedly. Hope there's a Version 2 coming ;)

Waiting for the part where it suddenly attacks your face :P
