Many companies from different countries were there, exhibiting their products for various markets: Industrial, Military, Healthcare, Entertainment, Education, Security and F&B (Food and Beverages) mainly.
From what I see, South Korea, Japan, India, China, and Singapore are taking the lead in the Asian robotics markets, but some big "western" companies, like ABB or Universal Robots are also doing big business here in Asia.
One of the reasons of having a good growth in robotics development and adoption in Asia is due to the specific Government's grants for this purpose:
- Singapore: As I mentioned in my previous post, Singapore have its Industrial Transformation Programme (ITP) 
- South Korea will spend a total of 500 billion won (US$428 million) in the coming three years to foster the rapidly growing drone industry 
- Japan announced their well known Japan's Robot Strategy in 2015 
- China made robotics a focal point of its recent “Made in China 2025” Plan, and has set national goals of producing 100,000 industrial robots a year and having 150 robots in operation for every 10,000 employees by 2020 
Here you could see a small video I recorded as a summary of the companies and products exhibited in this past AREX 2016
