Can you believe a vision system in the size of an insect??

Insects are quite good at not running into things but even if they bump or run into things they are good at surviving. Bees make it more easy and convenient as they fly up to a small hole or gap, wander back and forth a little bit to collect visual information about where the edges of the gap are, and then push themselves through the gaps. It’s not fast but it’s reliable and doesn’t take much to execute. The basic motive is to recover a minimum amount of information that will be enough to complete the task that is assigned.

For detecting the gap, an optical-flow technique is used. It takes a picture first then moves a little bit, and then again takes another picture. It then identifies similar features in each picture, and the far away features behind the gap will appear to be the closer than before. The maximum speed that can be achieved by the passing through the gap was 2.5 m/ s. It was primarily constrained by the rolling shutter camera but again, this method wouldn't be good for high-performance drones so it has been coupled with the monocular camera
So pull up your sock guys cause its time for you can construct a quadcopter using your Expert level kit.
Impact of Local Restrictions - Partial, night, and complete lockdowns in certain parts of India.
As local governments across cities and states are taking action to stem the rapid rise in cases of Covid-19, certain restrictions are being put in place that impact delivery and warehouse operations also in certain Pin-codes.
Most of these impacts are small this time and we are working to ensure a smooth and delightful delivery experience for our customers, nevertheless there might be some delay in delivering orders in certain pin codes.
But most orders will be delivered in the stipulated time frame as we are working to further strengthen our backend logistics.
