This page shows Mechatronics Engineering bio-inspired robots, machines and smart products as designed and built by Frank and his students using a range of materials for the mechanical structure including low cost Cardboard Prototype Manufacturing. The cardboard robots are built using 1.5mm thick cardboard and just need cutting board, knife, rule and glue together with a precision eye for detail; technique lays the foundation for other manufacturing techiques such as 3d printing
|Frank has been awarded a USA patent 9,653,962. It is a completely new mechatronics machine that closely mimics biological muscle for dynamic agile animal robots…you can see it here at Technology Readiness Level 6, TRL6, see video clip below. Yes it’s noisy but it’s a prototype and the new design will be 100 times quieter. There are NO springs and there is NO stored energy in the system; it is a near-pure force producing device with thus near-zero output impedance, the first of its kind. You can programme a force-time signature thus controlling the force impulse, I(N-s)………..continued on right and up a bit…
|| …..Currently, maximum force is 1200N and minimum time of impulse is 0.05sec. Muscle actuator weighs 2.9kg-f. Moving system weighs 7.5kg-f. Yes that’s heavy but mass will be reduced 3 times and power will be increased 3 times for the new design coming soon.

It’s all about teaching students how to build robots that hit, throw and catapult ping pong balls accurately into a waste paper basket just like robot basketball.
The clip below gives you an idea of Frank’s style of teaching. There is a misleading idea in the narrative. When Frank says that “we teach the practical side of engineering at UNNC”, he means that “we”, in his Mechatronic Studio, teach with this style
Student paddle craft competition below at the University of Brunei Darussalam. Go to 4min 30sec for the competition. Boats made from cardboard and waterproofed with paint. Students had to program their boats to carry cargo weight from Brunei harbour to Malaysia Port Dickson harbour to Hong Kong harbour to Singapore harbour back to Brunei harbour in the shortest possible time. The more cargo weight you transport on your boat the more marks you get. The less time you take the more marks you get. Your total marks are equal to weight divided by time. This is an engineering project with a business twist in that it’s about transporting cargo efficiently. See the whole clip to see how fun-loving, innovative and creative these students are
|Engineering undergraduate students experimenting with paddle boat robots made from cardboard
|| Experimental skinny legged in-line leg hexapod with small servos
|Frank designs robots then design courses to teach students how to design robots. Here is Frank and his students assembling aluminium parts of a 3-wheeled robot that the students made in the workshop one week before
||…and here are the students doing programming and tests on the bench helped by my Taiwan colleague, Sean, who has a sense of humour
|Hexapod programmed to do outside epicyclic gear action. Imagine running a penny on the outside of your thumb and forefinger whose tips are touching forming a circle The penny is the robot
|| Frank’s Innovation and Design class 2007-8 project for 1st year University of Brunei Darussalam students in the engineering dept. This is Irnnie, Leong and Auzi having fun following the building of their Chateau Pomme de Terre potato shaping machine
|Compact hexapod with batteries inside the tubular body and range finder infra red whisker sensors
||Student project, Boby, Arland and Frank designed a first sight augmented reality hexapod gladiator sparring scenario. A bad guy robot comes to town saying he has waited long enough and takes a potshot in the central business district. The good robot on the right starts taking potshots at the bad guy robot with recoil, lights and sound. Eventually the bad guy robot receives 7 potshots and demises painfully then the good guy does a victory lap.

||Jumbo sized kinda Rubik Cube, but not really, fun project to use computer vision to place a coloured cube into place with all sides of Jumbo cube to have same colour. Each cube has a different colour on each of its six sides. The fork lift truck robot was a whole lot of fun building too
|Ping pong ball hitter with 10-ball magazine. Two out-of-phase driven servos are used to serve the ball into the tee. Only 6 balls basketed out of 10. Students have to figure out reasons for repeatability errors
||An experiment with a straight line pull back mechanism for a ping pong ball catapult robot…too complicated so abandoned in favour of simplified mechanism

This is Frank programming a CNC milling machine
A CNC (Computer Numerically Controlled) machine, is a high precision machine that you program to cut material, e.g. plastic, aluminium, into almost any shape you can imagine. The machine is a “subtractive” machine, i.e. it removes unwanted material from a block, as compared to an “additive machine”, e.g. a 3-d printer, that starts by building up a shape from nothing by adding tiny amounts of material to itself like bees when they build their hive. Both machines have their own advantages and disadvantages.
Dr. Francis Frank Nickols is an Associate Professor of Mechatronics and Control Engineering at University of Nottingham Ningbo China, UNNC. This is a British University in China, Zhejiang Province, city of Ningbo which is south of Shanghai on the eastern seaboard of China. Ningbo is a pleasant city with parks and canals everywhere and many people, including Frank, whizzing around on electric bikes. He was educated at Christ’s College, Cambridge University U.K. where he received a Bachelor degree in Engineering Science in 1978. Later he received a Masters degree in Electronic Systems Design from Cranfield University, U.K. and a Ph.D. degree in Mechatronics from University of Wales, College of Cardiff, U.K.
