I need to get the detailed mechanical design properly underway to ensure I haven't forgotten to order some critical parts.This blog covers design of the wheels and motor mounts.This video animates some of the CAD models to show their detail:www.youtu...

I finally have all four custom PCBs designed and on order so I can spend some time describing the system a bit better.The diagram below shows how all the electrical subsystems are connected in the GraffitiBot.Although this is a busy diagram with lots...

Reality struck. despite its 'formidable' looking track, my chasis cannot move properly on the grass.The video shows that it struggle to move on my garden grass. The motor driver is a ST L298 based motor driver.It is dual channel but limited to 2A per...

  Some component testing.....www.youtube.com/watch Electronic InterfacesThis blog describes the interface for all of the GraffitiBot sensors and actuators.The GraffitiBot beast includes 18 sensors, 10 motors, a mSD card, an LCD, a Blue...

I use a tracked chassis platform, which i ordered from Shenzen and it has arrived yesterday. Getting this shipped has gone through some drama. At first, the shipment is rejected by by forwarder, as it contains LiPo battery. I got to cancel the shipme...

This Sixth Sense design challenge is focused on sensors and this particular blog is focused on the TE Connectivity sensors that use a Wheatstone bridge architecture. Namely the FX1901 load cell and the KMT32B magnetic angle sensor.The FX1901 load cel...

I have just got a UPS update that my kit will reach on 26 Dec 18, right after Christmas. So i still can enjoy the Christmas holiday now. Anyway, the only update i have is i have decided to go for somewhat fail safe chain track chasis. It does comes w...

The past week has been about doing enough detailed design to get long lead time components on order.The parts kit from STMicroelectronics and TE Connectivity came in and I have been looking through the datasheets.Some parts I ordered have also come i...

We are back with a second blog post and this one is pretty interesting.Since our UAV Inspection system uses Quadcopter(s) to collect data, we decided on making a custom one for ourselves to meet our specific requirements. Quadcopters are infamou...

Hello everyone! Without wasting much time for the kit to arrive. Let me first give an introduction to what I do. I am member of Vjti Racing Team, Mumbai which is consist of 32 engineering enthusiast. My task is handling the entire electronic aspect o...

Title: Semi Automatic Fire Fighting RobotBy: sunnyiut Design Challenge: Sixth Sense Design ChallengeBlog number: 01 "Fire Fire Fire"!!!A serious issue. However, my project is not so serious to find a bullet-proof solution. Rather ...

GraffitiBot (Liquid Canvas Drawing (LCD) Robot)I wrote a proposal for this challenge back before the scope was relaxed to allow pre-existing RC robot platforms, so my design is still based on a fully autonomous robot built from scratch. This makes it...

Here is the venue of my weeding machineit is a bit undulating, with different types of weeds and other stuff i don't want to cut (carpet grass, flower, other edible plant). Hence the idea is to 'sixth sense' those objectsHere let's ta...
