Let's Make Robots!

Shipping LMR posters cost more than I thought. Please help.

Update: 301th July, 2013

Thanks to a few generous members of LMR half of the bill has been paid. I still have to pay a weeks pay but that is much better than 2. I still have another 350 posters that have not been shipped yet so I might have to find a cheaper shipping service and hope they do not get damaged in transit.

If you want to help LMR then please buy a poster or continue to donate money. Right now, all donated money will go towards paying for shipping cost.

Sneak preview of T'REX robot tank chassis prototype

 

Inspired by the Rip Saw tank, I have designed a new robot chassis called the T'REX tank chassis. I finally received all the parts for the prototype chassis. The entire chassis including gearboxes and tracks are all metal. The tracks have been anodized a gun metal grey colour.

Guangzhou Science Center robot competition

As an advisor to the Guangzhou Science Center I occasionally have to go there and do some work. This time I was one of their judges for a local robot competition. There were 2 categories, non-programmable robots for younger students and programmable robots for older students. All teams received a sheet of 2mm thick heavy duty cardboard for their chassis and a kit from DAGU that included:

A hexapod for my son to ride on - a big experiment

After seeing the weblink by bdk6 "inspiration for Hexapod builders" I was inspired. The video is of the "Mantis" turbo diesel all terrain hexapod.

Ok, I cannot afford to build a 2 tonne turbo diesel hexapod but I can build one big enough for my 8 year old son Shi Sen to ride on. My plan is to have almost the entire robot laser cut from 6mm plywood.

Updated preview of new re-configurable, all metal tank chassis

Update: Just did a motor test using a fully charged 3S LiPo. These motor / gearbox combos are very powerful and will need a Wild Thumper controller to handle the peak current.

No load current: 0.6A
Nominal load current: 3A
Stall current: 11A+ 

This is definitely going to be the tank version of Wild Thumper!

Advanced Robot Arm Project

This is a long term project to develop a robotic arm that is more advanced that traditional hobbyist arms using RC servos without being so expensive that only well funded universities can afford it. 

The first prototype gripper used standard RC servos while we experimented with the configuration as shown in the first video. Once I had a good gripper configuration I built a prototype arm for it as shown in the second video. This arm used a differential drive system with the goal being to keep the weight of the motors as close to the shoulder as possible.

My trip to Xinjiang China

My Company was invited to the city of Karamay in Xinjiang China to demonstrate our robots at a Science Festival. Xinjiang is in the North West corner of China and borders a number of other countries. We had a 5 hour flight from Guangzhou (formerly Cantong) to Urmaqi and then another 1 hour flight to Karamay Where we were met by a lovely lady who's English name was Jenny.
